Identification of AhR agonists in sediments of the Bohai and Yellow Seas using advanced effect-directed analysis and in silico prediction. JOURNAL OF HAZARDOUS MATERIALS 2022; 435:128908. [PMID: 35500338 DOI: 10.1016/j.jhazmat.2022.128908] [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: 02/24/2022] [Revised: 03/30/2022] [Accepted: 04/10/2022] [Indexed: 06/14/2023]
Abstract
Novel aryl hydrocarbon receptor (AhR) agonists were identified in coastal sediments in the Yellow and Bohai Seas by use of a combination of effect-directed analysis (EDA) and in silico prediction. A total of 125 sediments were screened for AhR-mediated potencies using H4IIE-luc bioassay. Great potencies were observed in organic extracts, mid-polar fraction (F2), and subfractions of F2 (F2.6-F2.9) of sediments collected from Nantong, Qinhuangdao, and Yancheng. Less than 15% AhR potencies could be explained by detected dioxin-like PAHs. Full-scan screening analysis was conducted for the more potent fractions using GC-QTOFMS to investigate the presence of unmonitored AhR agonists. A five-step prioritization strategy was applied; 92 candidate compounds satisfied all criteria. Among these chemicals, thirteen were evaluated for AhR efficacy. Six compounds; benz[b]anthracene, 6-methylchrysene, 2-methylbenz[a]anthracene, 1-methylbenz[a]anthracene, 1,12-dimethylbenzo[c]phenanthrene, and indeno[1,2,3-cd]fluoranthene, exhibited significant AhR-mediated efficacies. 1,12-dimethylbenzo[c]phenanthrene and indeno[1,2,3-cd]fluoranthene were identified as novel AhR agonists. Potency balance analysis showed that the six newly identified AhR agonists explained 0.4-100% of the total AhR-mediated potencies determined. Overall, combining EDA and in silico prediction applied in this study demonstrated the benefits of assessing the potential toxic effects of previously unidentified AhR agonists in sediments from the coasts of China and Korea.

Abstract
Chrysene, one of the basic polycyclic aromatic hydrocarbons (PAHs), has been reported to make damages to human health and living environment. Chronic obstructive pulmonary disease (COPD) is a progressive disorder with high morbidity and mortality. To investigate the role of chrysene in the development of COPD, male C57BL/6 mice were exposed to the cigarette smoke (CS) followed with the administration of chrysene. Morphological analyses indicated that chrysene caused earlier and severer pathological changes in CS-exposed mice. Besides, CS-exposed mice with chrysene treatment showed obvious collagen deposition, elevated α-smooth muscle actin (α-SMA) expression and reduced E-cadherin abundance at earlier stage, which suggested the acceleration and aggravation of pulmonary fibrosis. Moreover, quantification of leukocytes and pro-inflammatory cytokines in bronchoalveolar lavage fluid (BALF) and lung tissues implied that chrysene significantly exacerbated the proceeding of inflammation in CS-exposed mice. Furthermore, significantly increased apoptotic rates, augmented expressions of apoptotic related proteins and highly expressed TRPV1 were determined in CS-exposed mice with chrysene treatment, which indicated the association between COPD pathogenesis and TRPV1 channel. In summary, our findings elucidate that chrysene accelerates the development of COPD in a murine model with new molecular mechanisms.

Abstract
The need to include alkylated polycyclic aromatic hydrocarbons in human health risks assessments for oil contaminated seafood after crude oil spills is set forth. This is placed within the context of a brief review of the literature for PAHs and human health risk assessments after oil spills. The example of human health risk assessments for oil contaminated seafood after the Deepwater Horizon oil spill is reviewed with the conclusion that PAHs such as alkylated chrysenes/triphenylenes/benzanthracenes should have been included in the human health risk assessment and not dismissed as present in very low concentrations relative to their parent PAHs.
