Abstract
Different isoforms of alkyl esters of p-Hydroxybenzoic acid, also known as parabens, are of great concern due to their widespread presence into the aquatic environment, their high concentrations in wastewater discharges, as well as their ability to induce adverse effects on aquatic organisms. Considering the imperative need for assessing their fate and risk to aquatic environment, the present study investigated the biological effects of two isoforms of parabens, methyl- (MeP) and propyl- (PrP), on the bacterium Aliivibrio fischeri (using the Bioluminescence Inhibition/Microtox® bioassay) and the mussel Mytilus galloprovincialis (in terms of mussel mortality, cellular, oxidative and genotoxic stress indices). The assessment of MeP and PrP behavior into aquatic media (artificial sea water/ASW and 2 % NaCl), primarily performed by UHPLC-UV-MS analysis, showed only a slight hydrolysis of PrP to 4-Hydrobenzoic acid (4-HBA). Furthermore, exposure of both species to different concentrations of each paraben revealed differences among their toxic potential, as well as their ability to cause cellular, oxidative and genotoxic effects on hemocytes of challenged mussels. Interestingly, the Microtox® bioassay showed that PrP mediated toxicity in A. fischeri were more pronounced than MeP, as revealed by the estimated toxic endpoints (in terms of concentration that promote 50 % of bioluminescence inhibition, EC50). Similarly, in challenged mussels, a significant disturbance of mussel hemocytes' lysosomal membrane integrity, as well as enhanced levels of superoxides, nitric oxides, lipid peroxidation byproducts, and micronuclei formation were observed. These findings are of great interest, since MeP and PrP differential toxic potential, as well their ability to induce pre-pathological alterations in marine species, like mussels, give new evidence for their risk to aquatic biota.

Abstract
Parabens are a family of endocrine-disrupting chemicals. Environmental estrogens may play a vital role in the development of lung cancer. To date, the association between parabens and lung cancer is unknown. Based on the 189 cases and 198 controls recruited between 2018 and 2021 in Quzhou, China, we measured 5 urinary parabens concentrations and examined the association between urinary concentrations of parabens and lung cancer risk. Cases showed significantly higher median concentrations of methyl-paraben (MeP) (2.1 versus 1.8 ng/mL), ethyl-paraben (0.98 versus 0.66 ng/mL), propyl-paraben (PrP) (2.2 versus 1.4 ng/mL), and butyl-paraben (0.33 versus 0.16 ng/mL) than controls. The detection rates of benzyl-paraben were only 8 and 6% in the control and case groups, respectively. Therefore, the compound was not considered in the further analysis. The significant correlation between urinary concentrations of PrP and the risk of lung cancer (odds ratio (OR)adjusted = 2.22, 95% confidence interval (CI): 1.76, 2.75; Ptrend < 0.001) was identified in the adjusted model. In the stratification analysis, we found that urinary concentrations of MeP were significantly associated with lung cancer risk (OR = 1.16, 95% CI: 1.01, 1.27 for the highest quartile group). Besides, comparing the second, third, and fourth quartile groups with the lowest group of PrP, we also observed urinary PrP concentrations associated with lung cancer risk, with the adjusted OR of 1.52 (95% CI: 1.29, 1.65, Ptrend = 0.007), 1.39 (95% CI: 1.15, 1.60, Ptrend = 0.010), and 1.85 (95% CI: 1.53, 2.30, Ptrend = 0.001), respectively. MeP and PrP exposure, reflected in urinary concentrations of parabens, may be positively associated with the risk of lung cancer in adults.

Abstract
BACKGROUND Endocrine-disrupting chemicals have been shown to cause toxicity in different systems of the body including the endocrine, cardiovascular and nervous systems. This study aims to analyze the adverse effects of Methylparaben (MP) on cardiac functions, neurodevelopment, and behavior of zebrafish. METHODS AND RESULTS Adult male and female zebrafish were exposed to MP for 30 days to study the toxicity effects. Zebrafish were grouped into control, solvent control, 1/10th (110 ppb), 1/100th, and 1/1000th (1 ppb) lethal concentration 50 of MP. Neurobehavioral assays, acetylcholinesterase (AChE) activity, serotonin levels, and expression of genes-Hypoxia-inducible factor 1 alpha, Neurotrophic Receptor Tyrosine Kinase, Paired box protein Pax-6, and tnnt2 were investigated in zebrafish. Results of the study showed more anxiety-like behavior in MP-treated female zebrafish when compared to males on chronic exposure. There was a dose-dependent reduction of AChE activity in both male and female zebrafish. Female zebrafish showed a dose-dependent increase in serotonin level on MP exposure while male zebrafish showed a dose-independent decrease in serotonin level. On MP exposure, there was also a dose-dependent dysregulation in the expression of cardiac hypoxia and neuronal differentiation-related genes in female zebrafish while a dose-independent change was observed in male zebrafish. CONCLUSION Chronic MP exposure affects cardiac functions, neuronal functions, and behavior of zebrafish by exhibiting changes in AChE activity, serotonin levels, and altering the expression of genes related to cardiac hypoxia and neuronal differentiation even at sub-lethal doses.

Abstract
Parabens, esters of para-hydroxybenzoic acid, are commonly used as antimicrobial preservatives in cosmetics and personal care products. Although several studies report exposure of humans to parabens in Western countries, little is known about exposure of humans to parabens in Asian countries. In this study, we determined concentrations of six parabens in spot urine samples collected from nine countries and estimated daily intakes (DI) and potential health risks of parabens. Ethyl-paraben, methyl-paraben, and propyl-paraben were detected frequently at 100, 98.0, and 80.3%, respectively, with representative median concentrations of 0.68, 7.02, and 1.21 ng/mL, respectively, for all nine countries. Urine samples from females (total median concentration: 32.3 ng/mL) contained significantly higher concentrations of parabens than did those from males (5.46 ng/mL). Urine samples from Korea (total median paraben concentration: 227 ng/mL) had the highest concentrations, which were one to two orders of magnitude higher than those found in other countries (3.67-29.1 ng/mL). The estimated DI of parabens (on the basis of concentrations measured in urine) varied widely, and several samples had propyl-paraben exposures above the acceptable DI. Our results suggest that paraben exposure is ubiquitous in Asian countries, and further assessment of potential health risk of these chemicals is needed.
