Differential developmental effects and its potential mechanism of long-term exposure to TBBPA in two generations of marine medaka (Oryzias melastigma) during early life stages. JOURNAL OF HAZARDOUS MATERIALS 2025; 491:137961. [PMID: 40120263 DOI: 10.1016/j.jhazmat.2025.137961] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/10/2024] [Revised: 02/27/2025] [Accepted: 03/13/2025] [Indexed: 03/25/2025]
Abstract
Tetrabromobisphenol A (TBBPA), a most widely used brominated flame retardant, has been detected in worldwide aquatic environments. However, the effects and mechanisms of TBBPA at environmentally realistic levels have not been well characterized in aquatic organisms. This study aims to investigate the impact of TBBPA on developmental toxicity and endocrine system in two generations of marine medaka (Oryzias melastigma) during early life stages. The results revealed that the embryos under exposure to environmentally relevant concentrations of TBBPA (0, 5, 50, and 500 μg/L) resulted in accelerated hatching and growth development in F0 generation. Conversely, delayed hatching, decreased hatch rate, and growth inhibition were observed in the F1 generation. Moreover, TBBPA disrupted the levels of THs (thyroid hormones), GH (growth hormone), and IGF (insulin growth factor). The gene transcriptional profiling implies modified gene expressions in the HPT axis, GH/IGF axis, and endoplasmic reticulum stress. The molecular docking analysis confirmed the binding affinity of TBBPA to key endocrine-related proteins, which partially elucidates the mechanism of endocrine disruption and developmental abnormalities. Endoplasmic reticulum stress may explain the developmental differences between the two generations. This was the first study to explore the multigenerational developmental toxicity of TBBPA to marine fish, which is essential for ecological risk assessment of this emerging pollutant.

Sun H, Ye L, Yang M, Su G. High-resolution mass spectrometry recognized Tetrabromobisphenol A bis (2,3-dibromo-2-methylpropyl ether) (TBBPA-DBMPE) as a contaminant in sediment from a flame retardant manufacturing factory. WATER RESEARCH 2025; 283:123783. [PMID: 40373377 DOI: 10.1016/j.watres.2025.123783] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/14/2025] [Revised: 04/28/2025] [Accepted: 05/04/2025] [Indexed: 05/17/2025]
Abstract
Information on contamination status of tetrabromobisphenol, and triazine-based novel brominated flame retardants (NBFRs) in sediment environment is very rare. Here, by use of high performance liquid chromatography coupled with quadrupole orbitrap mass spectrometry (HPLC-Q-Orbitrap/MS), we developed an analytical method for determination of three tetrabromobisphenol, and two triazine-based FRs in sediment samples. By applying this method for analysis of n = 6 sediment samples from a flame retardant manufacturing factory, we observed that total concentrations of 6 NBFRs (∑6NBFRs) ranged from 7.46 to 1020 ng/g dry weight (dw), which were comparable to those (3.83-820 ng/g dw) of n = 11 sediment samples from e-waste recycling area. Both of them were statistically significantly (p < 0.001, one-way ANOVA) higher than those in n = 10 sediment samples from Taihu Lake (1.22-8.22 ng/g dw). With an aim to find novel tetrabromobisphenol, and triazine-based compounds, we further investigated the ionization characteristics and the fragmentation patterns in ionization source of six target NBFRs. We observed that debromination, ether bond breakage, and the breakage of inter-benzene ring C-C and C-S bonds were the main in-source fragmentation pathways for TBBPA/S derivatives. On the basis of the observed ionization characteristics and an in-house suspect screening list, we tentatively identified 71 NBFR formulas, of which ten TBBPA/S derivatives and one triazine-based BFRs were found for the first time in sediments. Among these NBFR formulas, tetrabromobisphenol A bis (2,3-dibromo-2-methylpropyl ether) (TBBPA-DBMPE) is high of concern due to its male reproductive toxicity according to a recent study, and fully confirmed by comparing unique LC and HRMS characteristics of sediment sample with authentic standard. The work probably provides an opportunity for the structural identification of unknown TBBPA/S derivatives in environmental samples, and reports the occurrence of TBBPA-DBMPE in real environment.

Abstract
Tetrabromobisphenol A (TBBPA), a brominated flame retardant extensively used in consumer electronics, has been classified as a persistent environmental contaminant. While TBBPA-induced mitochondrial dysfunction is implicated in apoptosis, the precise oxidative stress-mediated mechanisms remain incompletely characterized. In this study, using human liver cancer cells (HepG2) as an in vitro model, we systematically investigated TBBPA's mitochondrial toxicity and associated cell death pathways. In vitro assays demonstrated that 10 μM TBBPA induced approximately 50 % cell death and reduced cell viability. This treatment also markedly elevated intracellular reactive oxygen species (ROS) levels. A comprehensive analysis of mitochondrial function, including assessments of mitochondrial membrane potential (MMP), oxygen consumption rate (OCR), ATP production, respiratory chain complex activities, and mitochondrial autophagy markers (LC3B, PINK1, Parkin), revealed that TBBPA entry into cells resulted in mitochondrial dysfunction. Furthermore, Ferroptosis biomarkers quantification further revealed TBBPA-driven Fe2+ and malondialdehyde (MDA) accumulation, coupled with upregulated expression of ferroptosis-related proteins (GPX4, SLC7A11, COX-2, Beclin-1). These findings provide novel insights into the molecular pathways underlying TBBPA-induced cytotoxicity.

Abstract
Novel bisphenol S (BPS) derivatives are being increasingly utilized as substitutes to bisphenol A (BPA) and BPS in thermal receipts and other industrial or commercial products. In recent years, the environmental occurrence, human exposure, and toxicity of non-chlorinated and chlorinated BPS derivatives have been investigated in numerous studies. This review summarizes the state-of-art and new knowledge on these aspects and provides recommendations for future research directions. The environmental analysis showed that BPS derivatives have been widely detected in paper products, water, indoor dust, sediment, and municipal sewage sludge. Recent studies have also reported the presence of non-chlorinated BPS derivatives, such as benzenesulfonylbenzene (DDS) and 4-(4-propan-2-yloxyphenyl)sulfonylphenol (BPSIP), in human breast milk, urine, and the maternal-fetal-placental unit. Toxicological studies suggest that BPS derivatives may cause a series of toxic effects, including endocrine-disrupting effects, cytotoxicity, hepatotoxicity, developmental toxicity, and neurotoxicity, some of which have been shown to exhibit adverse effects similar to or even greater than those of BPS. Future studies should focus on elucidating environmental occurrences, half-lives, sources for human exposure, and potential transformation pathways of BPS derivatives, as well as their toxic effects and underlying mechanisms.

Abstract
Efficient ionization is essential for sensitive mass spectrometry (MS) analysis. Herein, a novel laser-assisted electrospray ionization (laser-assisted ESI) source was developed to efficiently ionize low-polar and thermal unstable compounds. By irradiating the electrospray nozzle with a simple and low-cost laser probe (450 nm, 500 mW), the sample droplets were stimulated with a laser beam as well as the high voltage of the electrospray, which significantly enhanced the ionization efficiency. In positive ionization mode, by further utilizing the reaction of Ag+ and tetrabromobisphenol A bis(allyl ether) (TBBPA-BAE), the established laser-assisted ESI strategy was able to efficiently ionize the low-polar and thermal unstable TBBPA-BAE. Specifically, a limit of detection (LOD) of 14 ng L-1, linear range of 0.1-10 μg L-1 (R2 > 0.99), and relative standard deviations (RSDs) of 2.5% (n = 7, intraday) and 6.2% (n = 3 per day for 5 days, interday) were achieved. In negative ionization mode, laser-assisted ESI also improved the detection sensitivity of tetrabromobisphenol A (TBBPA), achieving a LOD of 3.3 ng L-1, linear range of 0.01-10 μg L-1 (R2 > 0.99), and RSDs of 4.7% (n = 7, intraday) and 7.3% (n = 3 per day for 5 days, interday). Compared to extractive electrospray ionization mass spectrometry (EESI-MS) and ESI-MS, the LODs achieved with laser-assisted ESI-MS were 54 and 16 times lower for the detection of TBBPA-BAE and TBBPA, respectively. Notably, deep purification and preconcentration were not required to accurately detect TBBPA and TBBPA-BAE in river water and wastewater treatment plant effluent. The spiked recoveries were between 88.0% and 106.0%, demonstrating the high reliability and practicality of this method.

Abstract
As emerging pollutants, bisphenol A (BPA), tetrabromobisphenol A (TBBPA) and its analogs have become widespread in the coastal environment of China. To investigate the occurrence of these novel contaminants in Chinese marginal sea, 176 seawater and 88 sediment samples were collected from the Yellow Sea and East China Sea. In seawater and sediment, the detection rates of TBBPA are 83.9 % and 100 %, BPA and 20 analogs were within 1.7 %-93.7 % and 1.1 %-100 %, respectively. In seawater, the concentrations of TBBPA and analogs were significantly higher in winter than in summer. But in sediment, there were no significant seasonal differences. The distribution of targets in 28 sampling points of the Yellow River and Yangtze River showed that industrial point source emissions have a greater impact on concentration. Fugacity analysis showed that BPA tends to diffuse from seawater to sediment while the TBBPA did the opposite. The maximum hazard quotients (HQ) of TBBPA and its analogs for three aquatic organisms indicated that they have high ecological risks, especially for complex organisms. Five suspected metabolites were identified by non-targeted screening. This study provides novel insights into the pollution status, dispersal behavior, and ecological risk of TBBPA and its analogs in the marine environment.

Abstract
Tetrabromobisphenol A (TBBP-A) is an emerging pollutant that enters water resources and affects various marine organisms, such as fish. Consequently, numerous studies globally investigated TBBP-A concentrations in fish fillets of the current study were meta-analyze concentration of TBBP-A in fish fillets and estimate the associated health risks for consumers. The search encompassed international databases, including Science Direct, PubMed, Scopus, Embase, and Web of Science from January 1, 2005, to July 20, 2023. The ranking of countries based on the pooled (Mean) concentration of TBBP-A in fish was as follows: China (1.157 µg/kg-ww) > Czech Republic (1.027 µg/kg-ww) > France (0.500 µg/kg-ww) ∼ Switzerland (0.500 µg/kg-ww) > Netherlands (0.405 µg/kg-ww) > Germany (0.33 µg/kg-ww) > Sweden (0.165 µg/kg-ww)>UK (0.078 µg/kg-ww) > Belgium (0.065 µg/kg-ww) > South Korea (0.013 µg/kg-ww) ∼ Japan (0.013 µg/kg-ww) > Ireland (0.005 µg/kg-ww). The risk assessment showed that the carcinogenic and non-carcinogenic risks of TBBP-A in China and France are higher compared to other countries; however, within all countries, these risks were found to be within acceptable limits.

Abstract
Tetrabromobisphenol A (TBBPA)-debrominated products has attracted growing concern in recent years. The sequential anoxic-oxic incubation approaches were effective in dissipation of environments containing halogenated xenobiotics. However, few studies focused on the submerged soil-plant systems, which appear common in environment. The present study characterised the fate and metabolites of TBBPA-debrominated products such as tribromobisphenol A (TriBBPA), 2,2'-dibromobisphenol A (2,2'-DiBBPA), 2,6-bromobisphenol A (2,6-DiBBPA), and monobromobisphenol A (MoBBPA) in submerged soils with an anoxic-oxic interface, with or without rice seedlings. The dissipation and translocation of TriBBPA, 2,2'-DiBBPA, 2,6-DiBBPA, and MoBBPA were reported for the first time. 2,6-DiBBPA showed the highest dissipation rate (half-life 3-3.5 days) compared with the dissipation rates (half-life 6.4-15.7 days) of TBBPA, TriBBPA, 2,2'-DiBBPA, and MoBBPA, and the highest non-extractable residues (0.21-30.8%) in soil generally. The presence of rice seedlings accelerated the breakdown of TBBPA and the TBBPA-debrominated products into bisphenol A, thereby reducing their binding to the soil. Methyl ethers of the debromination products (i.e., diMeO-MoBBPA, and MeO-MoBBPA) in soil were revealed for the first time. The logarithms (-3.03-0.85) of the translocation factors were negatively correlated with the octanol-water partition coefficients in the planted soil, indicating the significance of hydrophobicity in their transport. These findings reveal the impact of the anoxic-oxic interface on the fate and metabolism of TBBPA and TBBPA-debrominated products, supporting environmental risk assessment.

Abstract
Tetrabromobisphenol A (TBBPA), a brominated flame retardant (BFR), has been implicated as the neurotoxic effects in mammalian. However, the exact mechanisms underlying TBBPA-induced neurotoxicity remain unclear. In the present study, Neuro-2a cells, a mouse neural crest-derived cell line, were used to examine the mechanism of TBBPA-induced neuronal cytotoxicity. TBBPA exposure caused alterations in cell viability and mitochondrial membrane potential (MMP) and induction of apoptotic events, such as increased apoptotic cell population and cleaved caspase-3, -7, -9, and poly (ADP-ribose) polymerase (PARP) protein expression). TBBPA exposure triggered CCAAT/enhancer-binding protein (C/EBP) homologous protein (CHOP) activation. Transfection with CHOP-specific small interfering RNA (siRNA) obviously prevented the expression of CHOP protein and markedly attenuated MMP loss, and caspase-3 and -7 activation in TBBPA-exposed Neuro-2a cells. In addition, TBBPA exposure significantly evoked the phosphorylation of c-Jun N-terminal kinase (JNK), extracellular-signal regulated kinase1/2 (ERK1/2), p38-mitogen-activated protein kinase (p38-MAPK), and AMP-activated protein kinase (AMPK)α proteins. Pretreatment of cells with pharmacological inhibitors of p38-MAPK (SB203580) and AMPK (compound C), but not inhibitors of JNK (SP600125) or ERK1/2 (PD98059), effectively prevented the increase in caspase-3 activity, MMP loss, and activated CHOP and cleaved caspase-3 and -7 protein expression in TBBPA-treated cells. Notably, transfection with either p38α-MAPK- or AMPKα1/2-specific siRNAs markedly attenuated the expression of CHOP, and cleaved caspase-3 and -7. Interestingly, transfection with each siRNA significantly reduced the TBBPA-induced phosphorylation of p38-MAPK and AMPKα proteins. Collectively, these findings suggest that CHOP activation-mediated mitochondria-dependent apoptosis contributes to TBBPA-induced neurotoxicity. An interdependent p38-MAPK and AMPKα signaling-regulated apoptotic pathway may provide new insights into the mechanism understanding TBBPA-elicited neurotoxicity.

Zhang X, Xu Z, Zhang Y, Wan H, Zhao H. Tetrabromobisphenol A biotransformation in aged soil: Mechanism analysis induced by root exudates during rhizoremediation of Helianthus annus. JOURNAL OF HAZARDOUS MATERIALS 2024; 480:136089. [PMID: 39405712 DOI: 10.1016/j.jhazmat.2024.136089] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/22/2024] [Revised: 10/01/2024] [Accepted: 10/05/2024] [Indexed: 12/01/2024]
Abstract
Rhizoremediation, recognized as a progressive strategy for the removal of organic pollutants in soil, prominently focused on the influence of root exudates-induced alterations within the rhizosphere on the bioavailability and transformation of pollutants. However, the influence of root exudates on the ultimate fate of tetrabromobisphenol A (TBBPA) in soil remains unclear. The current study embarked on a comprehensive examination of the biotransformation process and underlying mechanisms of TBBPA driven by root exudates of Helianthus annus in rhizospheric soil. The pot experiment underscored the constructive impact of root exudates on enhancing the TBBPA dissipation efficiency within lab-controlled, with the increments of 18.77 %∼38.64 %. The core bacterial players responsible for TBBPA biotransformation were identified, with the prominent genus being Saccharibacteria_genera_incertae_sedis, unclassified_Sphingomonadaceae, and Parcubacteria_genera_incertae_sedis. In rhizospheric soil, a comprehensive analysis disclosed the presence of 20 different biotransformation products of TBBPA. Notably, root exudates were found to predominantly drive the reductive debromination pathway. This study provided for the first concrete evidence that root exudates can promote the desorption of TBBPA from soils. The current study aimed to decipher the molecular mechanisms in biotransformation process of TBBPA mediated by root exudates, and also provided reference for the environmental behavior of organic pollutants induced by root exudates.

Abstract
Knowledge of the biotransformation of tetrabromobisphenol A (TBBPA) and its related contaminants by human gut microbiota (GM) remains unexplored. Here, TBBPA and its four analogs were incubated with mixed GM strains, and nine rhamnosylated or debrominated transformation products (TPs) were discovered. Remarkably, rhamnosylation was identified as a common and unique microbial transformation pathway for these contaminants, and six of the seven rhamnosylated TPs were reported for the first time. Additionally, a kinetic transformation study also showed a rapid and strong bioaccumulation of TBBPA and TPs by Clostridium manihotivorum. Genomic analysis and phylogenetic studies identified C1.1_02053 as the gene encoding the C. manihotivorum working rhamnosyltransferase (CmRT), showing elevated gene expression with higher TBBPA exposure. Molecular docking identified five critical amino acid residues in CmRT that catalyze TBBPA rhamnosylation, and molecular dynamics simulations further confirmed the stability of the CmRT-TBBPA complex. Dynamic metabolomics analysis showed microbial growth-dependent disturbing effects in C. manihotivorum upon TBBPA exposure, and key metabolic pathways related to rhamnosyltransferase showed changes closely related to the transformation process. These findings provide insights into the unique transformation of environmental contaminants by the GM and highlight the disturbing effects of exogenous chemicals on the GM, as well as the potential impacts on overall human health.

Abstract
The effect and underlying mechanism of tetrabromobisphenol A (TBBPA), a plastic additive, on biofilm formation of methicillin-resistant Staphylococcus aureus (MRSA USA300) remain unknown. This study first investigated the impact of different concentrations of TBBPA on the growth and biofilm formation of USA300. The results indicated that a low concentration (0.5 mg/L) of TBBPA promoted the growth and biofilm formation of USA300, whereas high concentrations (5 mg/L and 10 mg/L) of TBBPA had inhibitory effects. Further exploration revealed that the low concentration of TBBPA enhance biofilm formation by promoting the synthesis of extracellular proteins, release of extracellular DNA (eDNA), and production of staphyloxanthin. RTqPCR analysis demonstrated that the low concentration of TBBPA upregulated genes associated with extracellular protein synthesis (sarA, fnbA, fnbB, aur) and eDNA formation (atlA) and increased the expression of genes involved in staphyloxanthin biosynthesis (crtM), suggesting a potential mechanism for enhanced resistance of USA300 to adverse conditions. These findings shed light on how low concentrations of TBBPA facilitate biofilm formation in USA300 and highlight the indirect impact of plastic additives on pathogenic bacteria in terms of human health. In the future, in-depth studies about effects of plastic additives on pathogenicity of pathogenic bacteria should be conducted. CAPSULE: The protein and eDNA contents in biofilms of methicillin-resistant Staphylococcus aureus are increased by low concentrations of TBBPA.

Inventorization and ecological risk assessment of tetrabromobisphenol A and hexabromocyclododecane in sediments from Guangdong coastal area of South China Sea. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 938:173527.

Abstract
Brominated flame retardants (BFRs) exhibit excellent flame retardant properties and are widely used in various industries. Among the common BFRs, tetrabromobisphenol A (TBBPA) and hexabromocyclododecane (HBCDs) pose substantial ecological and human health risks due to their extensive application and long-range transport. This study established 131 sample collection sites along the coast of the South China Sea (SCS) in Guangdong Province to assess the concentration, distribution, inventory, and ecological risk of TBBPA and HBCDs in surface sediments. The concentrations of TBBPA in SCS sediments ranged from < limit of detection (LOD) to 80 μg/kg dry weight (dw), and those of HBCDs from < LOD to 18 μg/kg dw. The diastereoisomers of HBCDs (α-, β-, and γ-HBCD) in the sediment samples accounted for 36 %, 13 %, and 51 %, respectively. Human activities, particularly those associated with nearby electronic waste disassembly and textile and garment industries, considerably influenced the dispersion of TBBPA and HBCDs. The inventories of TBBPA and HBCDs in Guangdong Province's SCS were estimated to be 3.2 × 105 kg and 7.2 × 104 kg, respectively. The average risk quotient values ranged from <0.01 to 0.016, indicating a low to negligible environmental risk. This study provides deeper insights into the distribution and scientific significance of HBCDs and TBBPA in SCS sediment samples, elucidates the current state of BFR contamination, and offers recommendations for future research on environmental safety and human health in the region.

Metabolic activity of gut microbial enrichment cultures from different marine species and their transformation abilities to plastic additives. ENVIRONMENT INTERNATIONAL 2024; 190:108882.

Abstract
The role of the gut microbiota in host physiology has been previously elucidated for some marine organisms, but little information is available on their metabolic activity involved in transformation of environmental pollutants. This study assessed the metabolic profiles of the gut microbial cultures from grouper (Epinephelus coioides), green mussel (Perna viridis) and giant tiger prawn (Penaeus monodon) and investigated their transformation mechanisms to typical plastic additives. Community-level physiological profiling analysis confirmed the utilization profiles of the microbial cultures including carbon sources of carbohydrates, amines, carboxylic acids, phenolic compounds, polymers and amino acids, and the plastic additives of organophosphate flame retardants, tetrabromobisphenol A derivates and bisphenols. Using in vitro incubation, triphenyl phosphate (TPHP) was found to be rapidly metabolized into diphenyl phosphate by the gut microbiota as a representative ester-containing plastic additive, whereas the transformation of BPA (a representative phenol) was relatively slower. Interestingly, all three kinds of microbial cultures efficiently transformed the hepatic metabolite of BPA (BPA-G) back to BPA, thereby increasing its bioavailability in the body. The specific enzyme analysis confirmed the ability of the gut microbiota to perform the metabolic reactions. The results of 16S rRNA sequencing and network analysis revealed that the genera Escherichia-Shigella, Citrobacter, and Anaerospora were functional microbes, and their collaboration with fermentative microbes played pivotal roles in the transformation of the plastic additives. The structure-specific transformations by the gut microbiota and their distinct bioavailability deserve more attention in the future.

Abstract
Tetrabromobisphenol S (TBBPS) is a brominated flame retardants (BFRs). TBBPS is widely used as a new type of BFR to replace TBBPA. Here, we used gastric cells as a model for evaluating the effect of TBBPS on the toxicology of gastric cells. Biochemical assays such as indirect immunofluorescence, cell proliferation assay were performed to analyze the toxicological effects of TBBPS on gastric cells. Cell proliferation analysis showed that TBBPS caused inhibition of gastric cell proliferation, and TBBPS induced gastric cell death. Further analysis showed that TBBPS led to ferroptosis and senescence of gastric cells by detecting ferroptosis-related marker molecules. Further work showed that TBBPS treatment resulted in lowered ferritin expression alongside heightened transferrin levels, which may be a potential molecular mechanism for TBBPS-induced ferroptosis and senescence in gastric cells. Here, our team investigates the effects of TBBPS on gastric cells in an in vitro model, and found that TBBPS caused toxicological damage to gastric cells. This study indicates potential toxic effects of TBBPS on the gastric cells, thereby providing a basis for further research into the toxicology of TBBPS.

Abstract
Tetrabromobisphenol A (TBBPA), a widely-used brominated flame retardant, has been revealed to exert endocrine disrupting effects and induce adipogenesis. Given the high structural similarities of TBBPA analogues and their increasing exposure risks, their effects on lipid metabolism are necessary to be explored. Herein, 9 representative TBBPA analogues were screened for their interference on 3T3-L1 preadipocyte adipogenesis, differentiation of C3H10T1/2 mesenchymal stem cells (MSCs) to brown adipocytes, and lipid accumulation of HepG2 cells. TBBPA bis(2-hydroxyethyl ether) (TBBPA-BHEE), TBBPA mono(2-hydroxyethyl ether) (TBBPA-MHEE), TBBPA bis(glycidyl ether) (TBBPA-BGE), and TBBPA mono(glycidyl ether) (TBBPA-MGE) were found to induce adipogenesis in 3T3-L1 preadipocytes to different extends, as evidenced by the upregulated intracellular lipid generation and expressions of adipogenesis-related biomarkers. TBBPA-BHEE exhibited a stronger obesogenic effect than did TBBPA. In contrast, the test chemicals had a weak impact on the differentiation process of C3H10T1/2 MSCs to brown adipocytes. As for hepatic lipid formation test, only TBBPA mono(allyl ether) (TBBPA-MAE) was found to significantly promote triglyceride (TG) accumulation in HepG2 cells, and the effective exposure concentration of the chemical under oleic acid (OA) co-exposure was lower than that without OA co-exposure. Collectively, TBBPA analogues may perturb lipid metabolism in multiple tissues, which varies with the test tissues. The findings highlight the potential health risks of this kind of emerging chemicals in inducing obesity, non-alcoholic fatty liver disease (NAFLD) and other lipid metabolism disorders, especially under the conditions in conjunction with high-fat diets.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 948:174799. [PMID: 39019271 DOI: 10.1016/j.scitotenv.2024.174799] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/14/2024] [Revised: 06/30/2024] [Accepted: 07/12/2024] [Indexed: 07/19/2024]
Abstract
As widely used alternative brominated flame retardants, tetrabromobisphenol S (TBBPS) and its derivatives have attracted increasing amounts of attention in the field of environmental science. Previous studies have shown that TBBPS and its derivatives easily accumulate in environmental media and may cause risks to environmental safety and human health. Therefore, to explore the environmental behaviours of TBBPS and its derivatives, in this paper, we summarized relevant research on the distribution of these compounds in water, the atmosphere, soil and food/biota, as well as their transformation mechanisms (biological and nonbiological) and toxic effects. The summary results show that TBBPS and its derivatives have been detected in water, the atmosphere, soil, and food/biota globally, making them a ubiquitous pollutant. These compounds may be subject to adsorption, photolysis or biological degradation after being released into the environment, which in turn increases their ecological risk. TBBPS and its derivatives can cause a series of toxic effects, such as neurotoxicity, hepatotoxicity, cytotoxicity, thyrotoxicity, genotoxicity and phytotoxicity, to cells or living organisms in in vitro and in vivo exposure. Toxicological studies suggest that TBBPS as an alternative to TBBPA is not entirely environmentally friendly. Finally, we propose future directions for research on TBBPS and its derivatives, including the application of new technologies in studies on the migration, transformation, toxicology and human exposure risk assessment of TBBPS and its derivatives in the environment. This review provides useful information for obtaining a better understanding of the behaviour and potential toxic effects of TBBPS and its derivatives in the environment.

Abstract
Tetrabromobisphenol A (TBBPA) and its derivatives are widely used as brominated flame retardants. Because of their high production and wide environment distribution, TBBPA derivatives have increased considerable concern. Previous studies have primarily focused on TBBPA, with limited information available on its derivative. In this study, we investigated the uptake, biotransformation and physiological response of two derivatives, Tetrabromobisphenol A bis(allyl ether) (TBBPA BAE) and Tetrabromobisphenol A bis(2,3-dibromopropylether) (TBBPA BDBPE), in Helianthus annus (H. annus) through a short-term hydroponic assay. The results revealed that H. annus could absorb TBBPA BAE and TBBPA BDBPE from solution, with removal efficiencies of 98.33 ± 0.5% and 98.49 ± 1.56% after 10 days, respectively, which followed first-order kinetics. TBBPA BAE was absorbed, translocated and accumulated while TBBPA BDBPE couldn't be translocated upward due to its high hydrophobicity and low solubility. The concentrations of TBBPA derivatives in plants peaked within 72 h, and then decreased. We identified twelve metabolites resulting from ether bond breakage, debromination, and hydroxylation in H. annus. The high-level TBBPA BAE suppressed the growth and increased malondialdehyde (MDA) content of H. annus, while TBBPA BDBPE didn't pose a negative effect on H. annus. TBBPA BAE and TBBPA BDBPE increased the activity of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT), with higher levels of these enzymes activity found in high concentration treatments. Contrastingly, TBBPA BAE exhibited higher toxicity than TBBPA BDBPE, as indicated by greater antioxidant enzyme activity. The findings of this study develop better understanding of biotransformation mechanisms of TBBPA derivatives in plants, contributing to the assessment of the environmental and human health impacts of these contaminants.

One electron oxidation-induced degradation of brominated flame retardants in electroactive membrane filtration system: Vital role of dichlorine radical-mediated process.

Abstract
Reactive chlorine species (RCS) are inevitably generated in electrochemical oxidation process for treating high-salinity industrial wastewater, thereby resulting in the competition with coexisting hydroxyl radicals (•OH) for oxidizing recalcitrant organic compounds. Due to the low redox potentials compared to •OH, the role of RCS has been often overlooked. In this work, we developed an electroactive membrane filtration (EMF) system that had a high removal efficiency (99.1 ± 0.5 %) for tetrabromobisphenol S (TBBPS) at low energy consumption (1.45 kWh m-3). Electron spin resonance spectroscopy and molecular probing tests indicated the predominance of Cl2•-, of which steady-state concentration (2.2 ×10-10 M) was extremely higher than those of ClO• (6.7 ×10-13 M), •OH (0.95 ×10-13 M), and Cl• (2.39 ×10-15 M). The density functional theory (DFT) and intermediate product analysis highlighted that Cl2•- radicals had a higher electrophilic attack efficacy than •OH radicals for inducing changes in the electron density of the carbon atoms around phenolic hydroxyl groups, thus leading to the generation of transition state intermediates and accelerating the degradation of TBBPS. Our work demonstrates the vital role of Cl2•- radicals for pollutant degradation, highlighting the potential of this technology for cost-effective removal of recalcitrant organic compounds from water and wastewater.

Abstract
The widespread occurrence of emerging brominated flame retardant tetrabromobisphenol S (TBBPS) has become a major environmental concern. In this study, a nanoscale zero-valent iron (nZVI) impregnated organic montmorillonite composite (nZVI-OMT) was successfully prepared and utilized to degrade TBBPS in aqueous solution. The results show that the nZVI-OMT composite was very stable and reusable as the nZVI was well dispersed on the organic montmorillonite. Organic montmorillonite clay layers provide a strong support, facilitate well dispersion of the nZVI chains, and accelerate the overall TBBPS transformation with a degradation rate constant 5.5 times higher than that of the original nZVI. Four major intermediates, including tribromobisphenol S (tri-BBPS), dibromobisphenol S (di-BBPS), bromobisphenol S (BBPS), and bisphenol S (BPS), were detected by high-resolution mass spectrometry (HRMS), indicating sequential reductive debromination of TBBPS mediated by nZVI-OMT. The effective elimination of acute ecotoxicity predicted by toxicity analysis also suggests that the debromination process is a safe and viable option for the treatment of TBBPS. Our results have shown for the first time that TBBPS can be rapidly degraded by an nZVI-OMT composite, expanding the potential use of clay-supported nZVI composites as an environmentally friendly material for wastewater treatment and groundwater remediation.

Abstract
Tetrabromobisphenol A (TBBPA) and Perfluorooctane sulfonate (PFOS) are emerging contaminants which coexist in marine environments, posing significant risks to ecosystems and human health. The behavior of these contaminants in the presence of dissolved organic matter (DOM), specifically the co-contamination of TBBPA and PFOS, is not well understood. The bioaccumulation, distribution, elimination, and toxic effects of TBBPA and PFOS on thick-shell mussels (Mytilus unguiculatus V.), with the absence and presence of humic acid (HA), a typical DOM, were studied. The results showed that the uptake of TBBPA decreased and the uptake of PFOS increased when exposed to 1 mg/L HA. However, at higher concentrations of HA (5 and 25 mg/L), the opposite effect was observed. Combined exposure to HA, TBBPA, and PFOS resulted in oxidative stress in the digestive gland, with the severity of stress dependent on exposure time and HA dose. Histological analysis revealed a positive correlation between HA concentration and tissue damage caused by TBBPA and PFOS. This study provides insights into the influence of HA on the bioaccumulation-elimination patterns and toxicity of TBBPA and PFOS in marine bivalves, offering valuable data for ecological and health risk assessments of combined pollutants in aquatic environments rich in DOM.

Abstract
Tetrabromobisphenol A (TBBPA) and tetrabromobisphenol S (TBBPS) have been widely used as additives in various products; however, their residues damage human health mainly via dietary ingestion. The current detection techniques remain challenging in directly and sensitively identifying TBBPA and TBBPS from food samples. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) has great potential as an alternative tool for the analysis of low-mass environmental pollution. Herein, we successfully screened and optimized COOH-MNP-COOH as a novel MALDI matrix to enhance deprotonation for the analysis of TBBPA and TBBPS from animal-derived food samples in negative-ion mode. Notably, COOH-MNP-COOH was synthesized by a facile self-assembly strategy and characterized by TEM, FT-IR, UV-vis, and zeta potential analysis. Compared with conventional and control matrices, the COOH-MNP-COOH matrix exhibited excellent performance of TBBPA and TBBPS with high chemical stability, favorable reproducibility, remarkable salt and protein tolerance, and high sensitivity owing to abundant active groups, stronger UV-vis absorption at 355 nm, and better hydrophilicity and biocompatibility. TBBPA and TBBPS were detected with the assistance of an internal standard with limits of detection (LODs) of 300 and 200 pg/mL, respectively. Moreover, this method was applied to directly identify the residues of TBBPA and TBBPS in milk products, followed by basa catfish and meat. This research may provide a promising approach for the analysis of environmental pollutants in foodstuffs.

First insights into the bioaccumulation, biotransformation and trophic transfer of typical tetrabromobisphenol A (TBBPA) analogues along a simulated aquatic food chain. JOURNAL OF HAZARDOUS MATERIALS 2024; 465:133390. [PMID: 38163409 DOI: 10.1016/j.jhazmat.2023.133390] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Revised: 11/28/2023] [Accepted: 12/26/2023] [Indexed: 01/03/2024]
Abstract
Tetrabromobisphenol A (TBBPA) analogues have been investigated for their prevalent occurrence in environments and potential hazardous effects to humans and wildlife; however, there is still limited knowledge regarding their toxicokinetics and trophic transfer in aquatic food chains. Using a developed toxicokinetic model framework, we quantified the bioaccumulation, biotransformation and trophic transfer of tetrabromobisphenol S (TBBPS) and tetrabromobisphenol A di(allyl ether) (TBBPA-DAE) during trophic transfer from brine shrimp (Artemia salina) to zebrafish (Danio rerio). The results showed that the two TBBPA analogues could be readily accumulated by brine shrimp, and the estimated bioconcentration factor (BCF) value of TBBPS (5.68 L kg-1 ww) was higher than that of TBBPA-DAE (1.04 L kg-1 ww). The assimilation efficiency (AE) of TBBPA-DAE in zebrafish fed brine shrimp was calculated to be 16.3%, resulting in a low whole-body biomagnification factor (BMF) in fish (0.684 g g-1 ww). Based on the transformation products screened using ultra-high-performance liquid chromatograph-high resolution mass spectrometry (UPLC-HRMS), oxidative debromination and hydrolysis were identified as the major transformation pathways of TBBPS, while the biotransformation of TBBPA-DAE mainly took place through ether bond breaking and phase-II metabolism. Lower accumulation of TBBPA as a metabolite than its parent chemical was observed in both brine shrimp and zebrafish, with metabolite parent concentration factors (MPCFs) < 1. The investigated BCFs for shrimp of the two TBBPA analogues were only 3.77 × 10-10 - 5.59 × 10-3 times of the theoretical Kshrimp-water based on the polyparameter linear free energy relationships (pp-LFERs) model, and the BMF of TBBPA-DAE for fish was 0.299 times of the predicted Kshrimp-fish. Overall, these results indicated the potential of the trophic transfer in bioaccumulation of specific TBBPA analogues in higher trophic-level aquatic organisms and pointed out biotransformation as an important mechanism in regulating their bioaccumulation processes. ENVIRONMENTAL IMPLICATION: The internal concentration of a pollutant in the body determines its toxicity to organisms, while bioaccumulation and trophic transfer play important roles in elucidating its risks to ecosystems. Tetrabromobisphenol A (TBBPA) analogues have been extensively investigated for their adverse effects on humans and wildlife; however, there is still limited knowledge regarding their toxicokinetics and trophic transfer in aquatic food chains. This study investigated the bioaccumulation, biotransformation and trophic transfer of TBBPS and TBBPA-DAE in a simulated di-trophic food chain. This state-of-art study will provide a reference for further research on this kind of emerging pollutant in aquatic environments.

Abstract
Tetrabromobisphenol A (TBBPA) and tetrabromobisphenol S (TBBPS) are widely distributed brominated flame retardants. While TBBPA has been demonstrated to stimulate adipogenesis, TBBPS is also under suspicion for potentially inducing comparable effects. In this study, we conducted a non-targeted metabolomics to examine the metabolic changes in 3T3-L1 cells exposed to an environmentally relevant dose of TBBPA or TBBPS. Our findings revealed that 0.1 µM of both TBBPA and TBBPS promoted the adipogenesis of 3T3-L1 preadipocytes. Multivariate analysis showed significant increases in glycerophospholipids, sphingolipids, and steroids relative levels in 3T3-L1 cells exposed to TBBPA or TBBPS at the final stage of preadipocyte differentiation. Metabolites set composed of glycerophospholipids was found to be highly effective predictors of adipogenesis in 3T3-L1 cells exposed to TBBPA or TBBPS (revealed from the receiver operating characteristic curve with an area under curve > 0.90). The results from metabolite set enrichment analysis suggested both TBBPA and TBBPS exposures significantly perturbed steroid biosynthesis in adipocytes. Moreover, TBBPS additionally disrupted the sphingolipid metabolism in the adipocytes. Our study presents new insights into the obesogenic effects of TBBPS and provides valuable information about the metabolites associated with adipogenesis induced by TBBPA or TBBPS.

[PMID: 38369010 DOI: 10.1016/j.tox.2024.153759] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Revised: 02/13/2024] [Accepted: 02/15/2024] [Indexed: 02/20/2024]
Abstract
Tetrachlorobisphenol A (TCBPA) and Tetrabromobisphenol S (TBBPS) are organic compounds widely used in industrial production, including in plastic and textile manufacturing. Presently, residual TCBPA is commonly detected in the environment as well as in human and animal sera. Therefore, it is imperative to assess the potential toxicological effects of TCBPA on organismal health. A series of biochemical experiments, including indirect immunofluorescence, ELISA, Western blot, MTT, etc, were conducted to analyze the effects of TCBPA on vascular smooth muscle cells. In this study, the biological impact of TCBPA on arterial smooth muscle cells (ASMCs) was investigated. CCK8 and EdU assays demonstrated significant proliferation of ASMCs following TCBPA treatment. Furthermore, TCBPA induced an inflammatory response in smooth muscle cells, as evidenced by the upregulated expression of inflammatory cytokines including IL-6, IL-1β, and MCP1. Additionally, we observed that TCBPA triggered an oxidative stress response in ASMCs by measuring ROS levels. To elucidate the underlying molecular mechanism of TCBPA-induced ASMC proliferation, we found that NLRP3 was essential for this process. Further investigation revealed that NLRP3 activation was mediated by NF-κB (which was activated by ROS). In summary, our findings suggest that TCBPA promotes the proliferation of ASMCs through the ROS/NF-κB/NLRP3 signaling cascade. This work indicates that TCBPA may represent a potential risk factor for the development of atherosclerosis, highlighting the need for judicious control of TCBPA usage.

Abstract
In this study, a novel functionalized magnetic composite (MNCGC) for magnetic solid-phase extraction of bisphenols from environmental and food samples was developed, featuring a multistep synthesis with Fe3O4, chitosan, graphene oxide, and β-cyclodextrin, crosslinked by glutaraldehyde. Characterization confirmed its advantageous morphology, intact crystal structure of the magnetic core, specific surface area, and magnetization, enabling efficient adsorption and separation via an external magnetic field. The optimized MSPE-HPLC-FLD method demonstrated excellent sensitivity, linearity, and recovery rates exceeding 80% for bisphenol pollutants, validating the method's effectiveness in enriching and detecting trace levels of bisphenols in complex matrices. This approach offers a new avenue for analyzing multiple bisphenol residues, with successful application to environmental water and food samples, showing high recovery rates.

Abstract
Brominated flame retardants (BFRs) are a group of contaminants of emerging environmental concern. In this study, systematic exploration was carried out to investigate the degradation of tetrabromobisphenol S (TBBPS), a typical emerging BFRs, by thermally activated persulfate (PDS) oxidation. The removal of 5.0 μM TBBPS was 100% after 60 min oxidation treatment under 60°C. Increasing the temperature or initial PDS concentration facilitated the degradation efficiency of TBBPS. The quenching test indicated that TBBPS degradation occurred via the attack of both sulphate radicals and hydroxyl radicals. Natural organic matter (NOM) decreased the removal rate, however, complete disappearance of TBBPS could still be obtained. Six intermediate products were formed during reactions between TBBPS and radicals. Transformation pathways including debromination, β-Scission, and cross-coupling were proposed. Brominated disinfection by-products (DBPs) in situ formed during the degradation of TBBPS were also investigated, such as bromoform and dibromoacetic acid. The presence of NOM reduced the formation rates of brominated DBPs. Results reveal that although thermo-activated PDS is a promising method for TBBPS-contaminated water, it can lead to potential brominated DBPs risks, which should be paid more attention to when SO4•--based oxidation technology is applied.

Abstract
In recent years, there has been growing concern over the rising incidence of liver diseases, with increasing exposure to environmental toxins as a significant contributing factor. However, the mechanisms of liver injury induced by environmental pollutants are largely unclear. Here, using tetrabromobisphenol A (TBBPA), a widely used brominated flame retardant, as an example, environmental toxin-induced liver toxicity in mice is characterized via single-cell sequencing technology. Heterogeneous gene expression profiles after exposure to TBBPA in major cell types of the liver are demonstrated. In hepatocytes, pathway analysis of differentially expressed genes reveals the enhanced interferon response and diminished metabolic processes. The disrupted endothelial functions in TBBPA-treated cells are then shown. Moreover, the activation of M2-polarization in Kupffer cells, as well as activated effector T and B cells are unveiled in TBBPA-treated cells. Finally, ligand-receptor pair analysis shows that TBBPA disrupts cell-cell communication and induces an inflammatory microenvironment. Overall, the results reveal that TBBPA-induced dysfunction of hepatocytes and endothelial cells may then activate and recruit other immune cells such as Kuffer cells, and T/NK cells into the liver, further increasing inflammatory response and liver injury. Thus, the results provide novel insight into undesiring environmental pollutant-induced liver injury.

Abstract
Tetrabromobisphenol A (TBBPA), a ubiquitous brominated flame-retardant environmental pollutant, has been reported to cause reproductive toxicity by chronic exposure. However, the acute reproductive risk and mechanisms of TBBPA toxicity to individuals, especially at environmentally relevant levels, remains a topic of debate. In this study, Caenorhabditis elegans was used to investigate the reproductive toxicity of acute exposure to TBBPA at environmentally relevant doses. The reproductive end points (embryonic lethality ratio and brood size), oxidative stress, sperm activation, and molecular docking were evaluated. Results showed that, after 24 h of TBBPA treatment, even at the lowest concentration (1 μg/L), the embryonic lethality ratio of C. elegans increased significantly, from 1.63 % to 3.03 %. Furthermore, TBBPA induced oxidative stress with significantly increased expression of sod-3 in C. elegans, which further raised the level of reproductive toxicity through inhibiting the activation of sperm in nematodes. In addition, molecular docking suggested TBBPA might compete for the glucose-6-phosphate-binding site of glucose-6-phosphate 1-dehydrogenase, resulting in oxidative stress generation. Accordingly, our findings indicate that even acute exposure to environmental concentrations of TBBPA may induce reproductive toxicity through reducing sperm activation in nematodes.

Abstract
Tetrabromobisphenol A bis (allyl ether) (TBBPA-BAE) is an extensively used brominated flame retardant, which has raised considerable concern because of its neurotoxic and endocrine disruption effects on aquatic organisms. However, previous studies mainly focused on the parent compound before modification, tetrabromobisphenol A (TBBPA), and little information is available about the bioconcentration and biotransformation of TBBPA derivatives in fish. In this study, we investigated the tissue-specific uptake, elimination kinetic, and biotransformation of TBBPA-BAE in common carp (Cyprinus carpio). The fish were exposed to TBBPA-BAE at environmentally relevant concentrations (20 μg·L-1) for 28 days, followed by 14 days of depuration. The results showed TBBPA-BAE could rapidly accumulate in common carp. Among the seven tissues studied, the highest concentrations of TBBPA-BAE were observed in the liver (6.00 μg·g-1 wet weight [ww]) on day 24, while the longest residence time was observed in the kidney (t1/2 values of 18.7 days). Biotransformation of TBBPA-BAE was documented in the in vivo experiments, and 14 different phase I and phase II metabolites were identified in the liver. These findings suggest the biotransformation products of TBBPA-BAE should be considered for a comprehensive risk evaluation.

Abstract
Tetrabromobisphenol A-bis(2,3-dibromopropyl ether) (TBBPA-BDBPE), a widely used flame retardant, has been frequently detected in various environmental compartments, but its health hazard remains largely unknown. Here, we investigated the adverse effects of TBBPA-BDBPE (50 and 1000 μg/kg/day) on postnatal testis development in CD-1 mice and the underlying mechanism. Following the first week of maternal exposure, neonatal mice in the high-dose group exhibited reduced seminiferous tubule area, fewer Sertoli cells and germ cells, and damaged microtubules in Sertoli cells; even microtubule damage was also observed in the low-dose group. When exposure extended to adulthood, male offspring in the high-dose group presented more remarkable alterations in reproductive parameters, including reduced sperm count; in the low-dose group, microtubule damage was also observable, along with blood-testis barrier impairment. Further molecular docking analysis and tubulin polymerization assay indicated that TBBPA-BDBPE could interact with tubulin and disrupt its polymerization. Moreover, we observed attenuated microtubules in mouse Sertoli cells in vitro (TM4) following TBBPA-BDBPE treatment, suggesting that TBBPA-BDBPE impaired testis development possibly by interfering with tubulin dynamics. This study not only highlights the male reproductive hazard of TBBPA-BDBPE but also greatly improved the understanding of the molecular mechanism for male reproductive toxicity of chemicals.

Abstract
Tetrabromobisphenol A (TBBPA) is the most abundant brominated flame retardant and bisphenol A (BPA) is often identified as the metabolic product of TBBPA. Both of them are highly bioconcentrated and show serious biological toxicity. In this study, an analytical method was optimized to simultaneously determine TBBPA and BPA in plant samples. Moreover, the uptake and metabolism of TBBPA in maize were investigated through hydroponic exposure experiment. The whole analysis procedure included ultrasonic extraction, lipid removal, purification by solid-phase extraction cartridge, derivatization, and detection by GC/MS. Optimizations were conducted for each pretreatment step above. After improvement, methyl tert-butyl ether (MTBE) was chosen as the extraction solvent; the lipid removal was conducted by repartition between organic solvent and alkaline solution. The best suitable pH condition is 2-2.5 for the inorganic solvent before used for further purification by HLB and silica column with the optimized elute solvent of acetone and mixtures of acetone and hexane (1:1), respectively. The recoveries of TBBPA and BPA spiked in maize samples were 69±4% and 66±4% with the relative standard deviation less than 5%, respectively, for the entire treatment procedure. Limits of detections were 4.10 ng/g and 0.13 ng/g for TBBPA and BPA in plant samples, respectively. In the hydroponic exposure experiment (100 μg/L, 15 d), the concentrations of TBBPA in maize cultivated in pH 5.8 and pH 7.0 Hoagland solutions were 1.45 and 0.89 μg/g in roots and 8.45 and 6.34 ng/g in stems, while they were all below the detection limit for leaves, respectively. The distribution of TBBPA in different tissues was as the following order: root>>stem>leaf, illustrating the accumulation in the root and the translocation to the stem. The uptake variations under different pH conditions were attributed to the change of TBBPA species, now that it shows greater hydrophobicity at lower pH condition as a kind of ionic organic contaminant. Monobromobisphenol A and dibromobisphenol A were identified as metabolisms products of TBBPA in maize. The efficiency and simplicity of the method that we proposed characterize its potential application as a screening tool for environmental monitoring and contribute to a comprehensive study of the environmental behavior of TBBPA.

Tetrabromobisphenol A (TBBPA) and its derivatives are regarded as new contaminants, raising much attention on their environmental occurrence and fates. However, the sensitive detection of TBBPA and its main derivatives is still a great challenge. This study investigated a sensitive method for simultaneous detection of TBBPA and its ten derivatives using high-performance liquid chromatography coupled with triple quadrupole mass spectrometry (HPLC-MS/MS) with atmospheric pressure chemical ionization (APCI) source. The method exhibited much better performance than previously reported methods. Furthermore, it was successfully applied in determining complicated environmental samples, including sewage sludge, river water and vegetable samples with concentration range from undetected (n.d.) to 25.8 ng g-1 dry weight (dw). For sewage sludge, river water and vegetable samples, the spiking recoveries of TBBPA and its derivatives ranged from 69.6 ± 7.0% to 86.1 ± 12.9%, 69.5 ± 13.9% to 87.5 ± 6.6%, and 68.2 ± 5.6% to 80.2 ± 8.3%, respectively; the accuracy ranged from 94.9 ± 4.6% to 113 ± 5%, 91.9 ± 10.9% to 112 ± 7%, and 92.1 ± 5.1% to 106 ± 6%, and the method quantitative limits ranged from 0.00801 to 0.224 ng g-1 dw, 0.0104-0.253 ng L-1, and 0.00524-0.152 ng g-1 dw, respectively. Moreover, the present manuscript describes for the first time the simultaneous detection of TBBPA and ten derivatives from various environmental samples, providing fundamental work for further research on their environmental occurrences, behaviors and fates.

Abstract
Tetrabromobisphenol A (TBBPA), Tetrachlorobisphenol A (TCBPA), Tetrabromobisphenol S (TBBPS) and their derivatives as the most widely used halogenated flame retardants (HFR), had been employed in the manufacturing industry to raise fire safety. HFRs have been shown to be developmentally toxic to animals and also affect plant growth. However, little was known about the molecular mechanism responded by when plants were treated with these compounds. In this study, when Arabidopsis was exposed to four HFRs (TBBPA, TCBPA, TBBPS-MDHP, TBBPS), the stress of these compounds had different inhibitory effects on seed germination and plant growth. Transcriptome and metabolome analysis showed that all four HFRs could influence the expression of transmembrane transporters to affect ion transport, Phenylpropanoid biosynthesis, Plant-pathogen interaction, MAPK signalling pathway and other pathways. In addition, the effects of different kinds of HFR on plants also have variant characteristics. It is very fascinating that Arabidopsis shows the response of biotic stress after exposure to these kinds of compounds, including the immune mechanism. Overall, the findings of the mechanism recovered by methods of transcriptome and metabolome analysis supplied a vital insight into the molecular perspective for Arabidopsis response to HFRs stress.

Occurrence, spatial distributions, and temporal trends of bisphenol analogues in an E-waste dismantling area: Implications for risk assessment. THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 867:161498.

Abstract
The environmental occurrences of bisphenol analogues (BPs) have been extensively reported, whereas their concentration profile, spatial distribution, and temporal trend in e-waste dismantling area are still poorly understood. Herein, typical BPs (BPA, BPS, TBBPA, TBBPA-DHEE, and TBBPA-MHEE) were investigated in water, soil, and biological samples from three representative regions (FJT, JJP, and RIB) in e-waste recycling area in Taizhou, Zhejiang Province. Overall, the detection frequency of BPs in all samples was 100 %, confirming widespread presence of BPs in e-waste recycling area. Wherein, BPA was the predominant BPs in water (33.3 %) and soil samples (34.9 %), but TBBPA accounted for the largest proportion (41.3 %) in biological samples. In addition, the concentration of BPs in FJT was lower than that in JJP and RIB owing to the renovations on FJT by the local government in recent years, whereas the higher BPs level in RIB implied that elevated BPs contents was related to massive e-waste dismantling activities. From 2017 to 2021, a decreased trend of BPs concentration was observed in FJT, but aggravation of BPs levels in RIB was caused by the ongoing e-waste dismantling. The risk assessment revealed that the BPs in e-waste recycling area posed a low ecological and human health risk. Our finding could provide a valuable reference for the development of strict legislation systems related to e-waste management in China.

Abstract
Human serum albumin (HSA) was used as a model protein to explore the effects of brominated flame retardant (BFR) binding and the corona formation on polystyrene nanoplastics (PNs). Under physiological conditions, HSA helped to disperse PNs but promoted the formation of aggregates in the presence of tetrabromobisphenol A (TBBPA, ΔDh = 135 nm) and S (TBBPS, ΔDh = 256 nm) at pH 7. At pH 4, these aggregates became larger with fewer electrostatic repulsion effects (ΔDh = 920 and 691 nm for TBBPA and TBBPS, respectively). However, such promotion effects as well as BFR binding are different due to structural differences of tetrabromobisphenol A and S. Environmental kosmotropes efficiently stabilized the structure of HSA and inhibited BFR binding, while the chaotropes favored bioconjugated aggregate formation. Such effects were also verified in natural seawater. The newly gained knowledge may help us anticipate the behavior and fate of plastic particles and small molecular pollutants in both physiological and natural aqueous systems.

Abstract
Tetrabromobisphenol A (TBBPA), a non-degradable environmental pollutant, was discharge into the air during the manufacture, use and recycling of plastic products. Respiratory exposure is the main way to inhalation of TBBPA. However, the research on the damage of TBBPA to the respiratory system is still extremely few. The aim of this experiment was to explore the mechanism of TBBPA toxicity to the lungs. Forty C57BL/6 J mice randomly divided into 4 groups, and the experimental groups with TBBPA at 10 n M/kg, 20 n M/kg and 40 n M/kg for 14 consecutive days. Histopathological and ultrastructural analysis showed that the inflammatory cells infiltrated and tissue structure damaged in the lung of mice with exposing to TBBPA. The ROS and MDA levels increase and the T-AOC, GSH-Px, CAT, SOD activities inhibition was found in lung tissue with TBBPA exposure. The expression of autophagy-related factors Beclin-1, P62, LC3-II, ATG5, and ATG7 decreased. The activation of NF-κB/TNF-α pathway indicates the occurrence of inflammation. The expression of Bax, caspase3, caspase7, caspase 9 increase, the expression of Bcl-2 decreased, and the apoptosis pathway activated. The autophagy inducer rapamycin can reverse the adverse effects of inflammation and apoptosis. Taken together, TBBPA inhibits autophagy-induced pneumonia and apoptosis by overproduction ROS.

Time- and dose-dependent detoxification and reproductive endocrine disruption induced by tetrabromobisphenol A (TBBPA) in mussel Mytilus galloprovincialis. MARINE ENVIRONMENTAL RESEARCH 2023; 183:105839. [PMID: 36481715 DOI: 10.1016/j.marenvres.2022.105839] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/08/2022] [Revised: 11/25/2022] [Accepted: 11/27/2022] [Indexed: 06/17/2023]
Abstract
As a typical brominated flame retardant (BFR), tetrabromobisphenol A (TBBPA) has been frequently detected in both biotic and abiotic matrices in marine environment. Our previous study found that genes related to metabolism phase I/II/III as well as steroid metabolism in Mytilus galloprovincialis were significantly altered by TBBPA treatment. However, the time- and dose-dependent response profiles of these genes to TBBPA exposure were rarely reported. In this study, the time- and dose-dependent effects of TBBPA on detoxification and reproductive endocrine disruption in M. galloprovincialis were explored by evaluating the responses of related gene expressions, enzymatic activities and gametogenesis to different concentrations of TBBPA (0.6, 3, 15, 75 and 375 μg/L) for different durations (14, 21 and 28 days). The results showed that the TBBPA accumulation increased linearly with the increases of exposure time and dose. Cytochrome P450 family 3 (CYP3A1-like) cooperated with CYP4Y1 for phase I biotransformation of TBBPA in mussels. The dose-response curves of phase II/III genes (glutathione-S-transferase (GST), P-glycoprotein (ABCB), and multidrug resistance protein (ABCC)) showed similar response profiles to TBBPA exposure. The common induction of phase I/II/III (CYPs, GST, ABCB and ABCC) suggested TBBPA detoxification regulation in mussels probably occurred in a step-wise manner. Concurrently, direct sulfation mediated by sulfotransferases (SULTs) on TBBPA was also the vital metabolic mechanism for TBBPA detoxification, which was supported by the coincidence between up-regulation of SULT1B1 and TBBPA accumulation. The significant promotion of steroid sulfatase (STS) might result from TBBPA-sulfate catalyzed by SULT1B1 due to its chemical similarity to estrone-sulfate. Furthermore, the promotion of gametogenesis was consistent with the induction of STS, suggesting that STS might interrupt steroids hydrolysis process and was responsible for reproductive endocrine disruption in M. galloprovincialis. This study provides a better understanding of the detoxification and endocrine-disrupting mechanisms of TBBPA.

Abstract
Tetrabromobisphenol A (TBBPA) is widely used in industrial production as a halogenated flame retardant (HFR). Its substitutes and derivatives are also commonly employed as HFRs. Consequently, they can be frequently detected in environmental and human samples. The potential developmental toxicity of TBBPA and its analogs, particularly to the human liver, is still controversial or not thoroughly assessed. Therefore, in this study, we focused on the early stages of human liver development to explore the toxic effects of those HFRs, by using a human embryonic stem cell liver differentiation model. We concluded that nanomolar treatments (1, 10, and 100 nM) of those pollutants may not exert significant interference to liver development and functions. However, at 5 μM doses, TBBPA and its analogs severely affected liver functions, such as glycogen storage, and caused lipid accumulation. Furthermore, TBBPA-bis(allyl ether) showed the most drastic effects among the six compounds tested. Taken together, our findings support the view that TBBPA can be used safely, provided its amounts are strictly controlled. Nonetheless, TBBPA alternatives or derivatives may exhibit stronger adverse effects than TBBPA itself, and may not be safer choices for manufacturing applications when utilized in a large and unrestricted way.

Abstract
Tetrabromobisphenol S (TBBPS) is a brominated flame retardant and a contaminant of emerging concern. Several studies found that sulfate radical (SO4•-) oxidation is effective to degrade TBBPS. Here, we demonstrate that the presence of nitrite (NO2-) at environmentally relevant levels causes dramatic changes in the kinetics and pathways of TBBPS degradation by SO4•-. Initially, NO2- suppresses the reaction by competing with TBBPS for SO4•-. At the same time, SO4•- oxidizes NO2- to form nitrogen dioxide radicals (NO2•), which actively react with some key TBBPS degradation intermediates, thus greatly altering the transformation pathway. As a result, 2,6-dibromo-4-nitrophenol (DBNP) becomes the primary TBBPS product. As TBBPS undergoes degradation, the released bromide (Br-) is oxidized by SO4•- to form bromine radicals and free bromine. These reactive bromine species immediately combine with NO2• or NO2- to form nitryl bromide (BrNO2) that in turn attacks the parent TBBPS, resulting in its accelerated degradation and increased formation of toxic nitrophenolic byproducts. These results show that nitryl halides (e.g., BrNO2 or ClNO2) are likely formed yet inadequately recognized when SO4•- is applied to remediate halogenated pollutants in the subsurface environment where NO2- is ubiquitously found. These insights further underscore the potential risks of the application of SO4•- oxidation for the remediation of halogenated compounds in realistic environmental conditions.

Abstract
Thyroid hormone (TH) signaling is a prerequisite of normal tissue function. Environmental pollutants with the potential to disrupt endocrine functions represent an emerging threat to human health and agricultural production. We used our Thyroid Hormone Action Indicator (THAI) mouse model to study the effects of tetrabromobisphenol A (TBBPA; 150 mg/bwkg/day orally for 6 days) and diclazuril (10.0 mg/bwkg/day orally for 5 days), a known and a potential hormone disruptor, respectively, on local TH economy. Tissue-specific changes of TH action were assessed in 90-day-old THAI mice by measuring the expression of a TH-responsive luciferase reporter in tissue samples and by in vivo imaging (14-day-long treatment accompanied with imaging on day 7, 14 and 21 from the first day of treatment) in live THAI mice. This was followed by promoter assays to elucidate the mechanism of the observed effects. TBBPA and diclazuril impacted TH action differently and tissue-specifically. TBBPA disrupted TH signaling in the bone and small intestine and impaired the global TH economy by decreasing the circulating free T4 levels. In the promoter assays, TBBPA showed a direct stimulatory effect on the hdio3 promoter, indicating a potential mechanism for silencing TH action. In contrast, diclazuril acted as a stimulator of TH action in the liver, skeletal muscle and brown adipose tissue without affecting the Hypothalamo-Pituitary-Thyroid axis. Our data demonstrate distinct and tissue-specific effects of TBBPA and diclazuril on local TH action and prove that the THAI mouse is a novel mammalian model to identify TH disruptors and their tissue-specific effects.

Developmental and Reproductive Impacts of Four Bisphenols in Daphnia magna. Int J Mol Sci 2022; 23:ijms232314561. [PMID: 36498889 PMCID: PMC9738221 DOI: 10.3390/ijms232314561] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Revised: 11/12/2022] [Accepted: 11/16/2022] [Indexed: 11/24/2022] Open
Abstract
Bisphenol A (BPA) is a typical endocrine-disrupting chemical (EDC) used worldwide. Considering its adverse effects, BPA has been banned or strictly restricted in some nations, and many analogs have been introduced to the market. In this study, we selected three representative substitutes, BPS, BPF, and BPAF, along with BPA, to assess the developmental and reproductive effects on Daphnia magna. The F0 generation was exposed to bisphenols (BPs) at an environmentally relevant concentration (100 μg/L) for 21 d; then the embryo spawn at day 21 was collected. Behavior traits, the activity of antioxidant enzymes, and gene transcription were evaluated at three developmental stages (days 7, 14, and 21). Notably, body length, heart rate, and thoracic limb beating were significantly decreased, and D. magna behaved more sluggishly in the exposed group. Moreover, exposure to BPs significantly increased the antioxidant enzymatic activities, which indicated that BPs activated the antioxidant defense system. Additionally, gene expression indicated intergenerational effects in larvae, particularly in the BPAF group. In conclusion, BPA analogs such as BPF and BPAF showed similar or stronger reproductive and developmental toxicity than BPA in D. magna. These findings collectively deepen our understanding of the toxicity of BPA analogs and provide empirical evidence for screening safe alternatives to BPA.

Multi-residue determination of bisphenol analogues in organism tissues by ultra-high performance liquid chromatography-tandem mass spectrometry. J Chromatogr A 2022; 1682:463489. [PMID: 36130425 DOI: 10.1016/j.chroma.2022.463489] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Revised: 09/02/2022] [Accepted: 09/05/2022] [Indexed: 11/22/2022]
Abstract
A reliable and sensitive analyzing method was developed and validated for determination of 13 novel bisphenol analogues (BPs) along with bisphenol A (BPA) in organism tissues. The complex organism tissues were treated by ultrasonic-assisted extraction using acetonitrile/formic acid (99:1, v/v), followed by successive purification using enhanced matrix removal-lipid sorbents and primary secondary amine sorbents. The BPs were finally determined by ultra-high performance liquid chromatography-tandem mass spectrometry after derivatization using pyridine-3-sulfonyl chloride. Satisfactory recoveries of 75 - 118% were obtained for the BPs, with good repeatability (RSD < 20%). Matrix interferences were efficiently diminished. The method quantification limits (MQLs) reached 0.003 - 0.1 ng g-1 dry weight (dw). The validated method was successfully applied to a preliminary investigation of the BPs in wild marine organisms collected from the nearshore waters along the coast of Guangdong, China. Besides BPA, novel BPs such as bisphenol F, bisphenol AF, and tetrabromobisphenol A were also detected at < MDL - 15.5 ng g-1 dw. This work laid a strong basis for further in-depth research on bioaccumulation of the novel BPs in the environment.

Identification and occurrence of TBBPA and its debromination and O-methylation transformation products in sediment, fish and whelks from a typical e-waste dismantling site. THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 833:155249. [PMID: 35427616 DOI: 10.1016/j.scitotenv.2022.155249] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/13/2022] [Revised: 03/24/2022] [Accepted: 04/09/2022] [Indexed: 06/14/2023]
Abstract
Tetrabromobisphenol A (TBBPA) and its debromination (∑BBPA) and O-methylation (∑MeO-TBBPA) products were widely detected in matched sediments, fish, and whelks samples collected from a typical electronic waste (e-waste) dismantling site in Southern China, with concentrations ranging from 19.8 to 1.52 × 104, 8.05 to 1.84 × 103, and 0.08 to 11.9 ng/g dry weight in sediments, and 6.96 to 1.97 × 105, 3.84 to 7.07 × 103, and 3.42 to 472 ng/g lipid in biotas, for TBBPA, ∑BBPA, and ∑MeO-TBBPA, respectively. Significantly higher concentrations of these targets were found in samples collected close to the e-waste site, indicating their potential e-waste sources. Tri-BBPA was the most abundant debromination products in sediments, whereas diMeO-TBBPA was the dominant O-methylation product in biotas. Relatively higher levels of diMeO-TBBPA found in liver and kidneys, suggesting these chemicals might be mainly derived from the in vivo biotransformation. Furthermore, significantly higher biota-sediment accumulation factor values were found for diMeO-TBBPA than these of TBBPA, indicating that O-methylation would increases their accumulation in aquatic organisms. Our study provides insights into the accumulation and biotransformation of TBBPA in aquatic systems. Further studies should pay attention to the occurrence as well as potential health risks of these transformation products.

Abstract
Tetrabromobisphenol S (TBBPS), an emerging brominated flame retardant, can cause neurotoxic and cytotoxic effects to human physiology. In this study, the degradation of TBBPS in Co2+ activated peroxymonosulfate (PMS) oxidation process was explored. In particular, brominated by-products formed during the degradation of the TBBPS were examined. It was found that TBBPS could be effectively removed in the Co2+/PMS oxidation process. The pseudo-first-order rate constants were 0.13 min-1 at 0.2 mM PMS and 0.5 μM Co2+ initially. It appeared that TBBPS degradation occurred via and HO attacks, but played a dominant role. The presence of natural organic matter (NOM) greatly inhibited the transformation of the TBBPS, which can be explained by the scavenging of the radical species. β-Scission, debromination, and cross-coupling were identified as the main reaction pathways of TBBPS degradation in the Co2+/PMS system. Further oxidation and ring-opening of the intermediates generated brominated by-products including bromoform, monobromoacetic acid, and dibromoacetic acid. The formation of the brominated by-products increased gradually in approximately 48 h. But, the presence of NOM reduced the yields of the brominated -by-products. The findings of this study indicate that organic bromine contaminants can be effectively removed but lead to brominated by-products in the activated PMS oxidation process, which should be taken into consideration when -based oxidation technology is applied.

Abstract
Endocrine-disrupting chemicals (EDCs) are ubiquitous in the environment, and human exposure to these pollutants has caused great public concern. Five groups of EDCs, including parabens, antimicrobials (triclosan (TCS) and triclocarban (TCC)), bisphenols (BPs), tetrabromobisphenol A and its alternatives (TBBPAs), and benzophenones, in urines of general populations from three cities with different economic levels in China were determined simultaneously to evaluate the coexposure levels of such chemicals. The total concentration of target compounds was approximately two times higher in the urines from Chengdu (a first-tier city; geometric mean: 2.50 μg/L) than that from Nantong (a second-tier city; 1.34 μg/L), and was one order of magnitude higher than that from Shehong (a fifth-tier city; 0.73 μg/L). Urinary target compounds were significantly correlated with gender, age, body mass index (BMI), education level, occupation, and diet. The estimated daily intakes of target chemicals ranged from 0.002 (benzophenones) to 10.2 µg/kg-bw/day (parabens). The exposure estimate showed that females were more vulnerable to exposure to these EDCs. This study profiles the regional and demographic-related differences in the concentrations and exposure risks of several typical EDCs in urines from general populations in three cities with different economic levels in China.

Abstract
Tetrabromobisphenol S (TBBPS), an emerging brominated flame retardant (BFR) has been widely detected in the environment, and may potentially pose environmental risks. However, data on the occurrence and toxic effects of TBBPS are limited. Circadian rhythms govern multiple behavioral and physiological processes, and their disruption is closely associated with various pathological conditions. Little is known about the potential for TBBPS to perturb circadian rhythm networks or circadian-driven locomotor behavior. In the present study, behavior assays and gene expression analysis based on circadian rhythm pathways were designed to investigate the potential circadian rhythm impairments and subsequent adverse effects caused in 120 h post-fertilization (hpf) zebrafish larvae by TBBPS. The development of embryos was inhibited by TBBPS exposure even at concentrations below the maximal non-lethal concentration (MNLC, 3.47 mg/L). Our results indicated remarkable alterations in the expression of several key circadian rhythm genes due to TBBPS exposure. Compared to control, the expression of per1a, per1b, per3, cry2, and csnk1da was increased, while the expression of clocka, clockb, cry4, cry1ba, arntl1a, and cank1db was decreased. Significant alterations of the circadian rhythm network could be observed in the zebrafish embryos. TBBPS exposure also significantly affected the behavioral responses of larvae. Our findings suggest the circadian rhythm network could be a potential target of TBBPS. Further study is needed to explore whether the transcriptional alterations in circadian rhythm translate into physiological effects.

Abstract
Novel halogenated flame retardants (HFRs) have attracted much attention due to their environmental hazard and adverse effects on human health. In this study, a sensitive and simultaneous method for the determination of six novel HFRs was developed, including tetrabromobisphenol A (TBBPA), tetrachlorobisphenolA, TBBPA bis(2-hydroxyethyl ether), TBBPA bis(allyl ether), TBBPA bis(2,3-dibromopropyl ether) and 2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine. ZIF-8 modified nitrogen-doped reduced graphene oxide (ZIF-8@N-rGO) was synthesized and coated onto a syringe filter to prepare a thin film microextraction (TFME) device. The adsorption capacities of ZIF-8@N-rGO for novel HFRs ranged from 50.98 to 112.84 mg g-1, exhibiting good extraction efficiency through a combination of π-π, hydrophobic, and hydrogen bonding interactions. The TFME device was coupled to a high-performance liquid chromatography-ultraviolet detection system to simultaneously determine target HFRs in crayfish-aquaculture water systems. Under the optimal extraction parameters, the linearities ranged from 0.1 to 100 ng mL-1. The method detection limits ranged from 0.030 to 0.14 ng mL-1 and relative recoveries ranged from 88.6 to 106.2%. We found that novel HFRs were detected in water and crayfish samples and were primarily distributed in the viscera and head shell of the crayfish. The bioconcentration factors ranged from 0.25 to 19.20 L kg-1, indicating non-bioaccumulation in the crayfish. This study provides valuable technology and information for potential health risks of exposure to novel HFRs from consuming crayfish.
