However, experimental evidence elucidating their toxicological mechanisms remains scarce. In this study, a novel mode-of-action (MOA)-based graph neural network (GNN) framework was introduced to (1) identify the molecular initiating event (MIE) through which LCMs disrupt immune homeostasis, (2) predict their binding affinity to 11β-hydroxysteroid dehydrogenase type 1 (HSD11B1), and (3) identify toxicity-relevant substructures to guide the molecular design of safer LCMs. First, an unsupervised clustering approach was applied to categorize over 1,400 LCMs into four structural clusters. Then, two virtual screening methods (<em>i.e.</em>, 2D/3D structural similarity analysis and a pharmacophore-based model) were applied to identify 121 possible receptors that could interact by potential insertions of LCM with a total universe of approximately 2,000 human protein receptors. Through “fingerprint”-based, t-distributed stochastic neighbor embedding (t-SNE) and molecular similarity analysis using PubChem, LCMs were found to be potential inhibitors of HSD11B1. Third, docking simulations revealed that highly fluorinated and ester-containing monomers exhibit stronger binding affinities at the HSD11B1 active site, primarily through stable hydrogen bonding. Finally, a GNN model was developed, which accurately predicted LCM-HSD11B1 binding affinities (<em>R</em><sup>2</sup> = 0.90, <em>RMSE</em> = 2.36) and identified key structural features contributing to immunotoxicity. Furthermore, a user-friendly, web-based prediction tool was developed to facilitate broader applications. These findings reveal HSD11B1 as a novel MIE of LCM-induced immunotoxicity and provide a practical immunotoxicity prediction platform to support risk assessment and the design of environmentally friendly LCM alternatives in LCD manufacturing.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"2 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145314820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study systematically evaluated the developmental neurotoxicity of representative benzophenone, benzotriazole, and triazine UVFs using human embryonic stem cell (hESC) differentiation models. The dynamic trajectories of both central and peripheral nervous system (CNS and PNS) development were tracked, revealing that UVFs induced an imbalanced CNS/PNS lineage commitment, with UV-328 particularly causing disruptions through direct modulation of the WNT signaling pathway. In the PNS, 10<!-- --> <!-- -->nM UV-328 significantly inhibited proliferation and migration in neural crest cells by preventing E-cadherin downregulation.

These findings elucidate the molecular mechanisms underlying benzophenone, benzotriazole, and triazine UVF-induced developmental neurotoxicity and underscore the critical need to evaluate the environmental impact and safety of UVFs during sensitive developmental stages.

Nevertheless, the precise mechanisms through which DEHP induces cardiac damage, particularly concerning myocardial injury, remain inadequately understood. Using a mouse model, this investigation employed UPLC-MS/MS to demonstrate that exposure to DEHP significantly elevated the concentration of its primary metabolite, mono(2-ethylhexyl) phthalate (MEHP), in cardiac tissue, while DEHP itself did not exhibit a significant difference. DEHP-induced myocardial injury in mice was evidenced by disorganized myocardial fibers, collagen deposition and elevated serum creatine kinase-MB (CK-MB) and C-reactive protein (CRP). Further analysis through database screening and experimental validation indicated that DEHP mediates myocardial injury by activating the sphingolipid metabolic pathway involving the sphingosine kinases 1 (SPHK1)/ sphingosine 1-phosphate receptor 2 (S1PR2) axis. Molecular docking and cellular thermal shift assays (CETSA) confirmed that MEHP could directly bind to and enhance the stability of SPHK1. DEHP exposure also increased pyroptosis-related proteins, reversible via SPHK1 inhibitor PF543 or S1PR2 siRNA. In conclusion, this study first links DEHP-induced cardiac pyroptosis to SPHK1/S1PR2 signaling in mice, providing novel insights into DEHP-associated cardiotoxicity, contributing to cardiac damage and thereby offering new theoretical insights into DEHP-related cardiac toxicity.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"171 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145306136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, our limited knowledge regarding the geometric characteristics of deposited MPs hinders the accurate assessment of associated environmental risks. This study explores how the geometrical characteristics influence MPs' selective atmospheric transport and deposition in Shanghai, which highlights MP geometric characteristics as a crucial indicator for understanding atmospheric-terrestrial transport mechanisms. High-density deposited MPs exhibited heterogeneous geometric characteristics, and low-density MPs showed partially homogenized characteristics. Meteorological parameters correlate more significantly with geometric characteristics than with deposition flux in our research. Precipitation significantly promotes deposited MPs characterized by high solidity, high circularity, and low density. Moreover, increased wind speeds driven by atmospheric pressure gradients significantly heightened the deposition of MPs with high solidity. Typhoon events enhance MP deposition by promoting the resuspension of terrestrial MPs and the release of MPs from damaged urban infrastructure. Potential source contribution function (PSCF) analysis indicates that both local and remote transport pathways contribute to MP deposition in Shanghai. These results provide critical insights for refining MP transport models by incorporating geometric features, elucidating the environmental fate of MP, and supporting the development of targeted strategies to mitigate human exposure risks.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"53 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145306137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Only a few field ISS studies have been published to-date and this work provides important practical considerations and performance data. Based on the results of a laboratory treatability study, RemBind® 100X, which consists of an aluminum hydroxide/carbon blend (amorphous aluminum hydroxide, kaolinite clay, and activated carbon), was applied at 3 percent by dry weight as a stabilizing material (or fixant) to impacted soil to reduce PFAS leaching from soil to groundwater. The fixant was distributed and mixed over a 3-foot vertical zone across a 100- x 100-foot area gridded into 18 test cells. Four performance monitoring events were completed throughout 19 months, during which soil samples were collected to assess PFAS leaching using Leaching Environmental Assessment Framework (LEAF) analysis, and vadose zone moisture was monitored using downhole nuclear magnetic resonance (NMR) imaging and in-situ moisture probes. For all PFAS analyzed, leachate concentrations following leachate testing, were reduced by at least 95 percent (±5.1%) for each of the four sampling events and concentrations were measured at levels less than the United States Environmental Protection Agency’s (USEPA’s) regional screening levels (OSD 2023) and maximum contaminant levels (EPA 2024) for PFOS, PFOA, perfluorobutanoic acid (PFBA), perfluorobutanesulfonic acid (PFBS), perfluorononanoic acid (PFNA), perfluorohexanoic acid (PFHxA), perfluorohexanesulfonic acid (PFHxS), and hexafluoropropylene oxide dimer acid (HFPO-DA). Furthermore, the approach was effective at reducing leaching from the stabilized soils, while still allowing infiltration of precipitation.

Here, we investigate the synergistic degradation of BP-3 by a bacterial consortium seeded from aerobic sludge WWTPs.
