Using integrated chemoassays, cell line bioassays, and chemical profiling, we assessed leachates from eight types of consumer plastic products following accelerated UV weathering equivalent to eight months of natural solar weathering in temperate regions to identify key contributors to leachate toxicity. Chemoassays, used as proxies for protein damage, showed UV-induced reactive toxicity, which increased by up to 82 % depending on plastic type. Cell-based bioassays revealed that UV exposure enhanced cytotoxicity up to 13-fold, especially for polyethylene leachates, in liver, skin, lung, and breast cancer cell lines, reflecting cell-specific vulnerabilities. UV exposure substantially altered the chemical composition of leachates shown by liquid chromatography -high resolution mass spectrometry (LC-HRMS) screening which identified 11 target-, 12 suspect-, and 90 non-target chemicals. Furthermore, UV exposure promoted the formation of more bioavailable and hazardous transformation products compared to the dark controls. The increased toxicity was primarily linked to the release and transformation of organic plastic-associated chemicals rather than microplastics or metal(loid)s. Overall, these findings highlight UV weathering as a critical driver of enhanced plastic leachate toxicity and emphasize the need for comprehensive chemical and toxicological assessments in environmental risk evaluations of plastics.</div></div>","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"498 ","pages":"Article 139791"},"PeriodicalIF":11.3,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009490","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}

To address this limitation, a novel composite spherical filter PU-H13@PP-AC, consisting of polyurethane foam immobilized with <em>Methylobacterium rhodesianum</em> H13 and packed into activated-carbon–modified polypropylene spheres—was synthesized and applied in a BTF (hereafter BTF3). To comparatively evaluate performance, two additional BTFs were operated with PU@PP (BTF1) and PU-H13@PP (BTF2) filters, and all systems were continuously tested for 155 days, including a starvation phase. PU-H13@PP-AC (BTF3) exhibited superior results, achieving biofilm formation 5–8 days faster than the controls, a removal efficiency of 88 % at 300 mg·m⁻³ and an elimination capacity 1.6–1.8 times higher than the other filters at an EBRT of 20 s. Following a 30-day starvation period, BTF3 rapidly recovered to 95.3 % removal within three days, demonstrating strong resilience. Mechanistic analyses indicated enhanced microbial adhesion, a higher proportion of viable cells (up to 97.5 %), and enrichment of functional taxa (<em>Proteobacteria</em>, <em>Methylobacterium</em>), accompanied by increased signaling molecules that improved stress resistance and long-term stability. These results demonstrate that PU-H13@PP-AC effectively overcomes major limitations of conventional BTFs by enabling rapid start-up, stable long-term operation, and high recovery capacity. The proposed filter therefore provides a cost-effective and environmentally friendly strategy for DCM emission control, offering practical potential for large-scale industrial VOC treatment.</div></div>","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"498 ","pages":"Article 139799"},"PeriodicalIF":11.3,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145009491","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}

Sensitivity regime analysis indicated that hourly O₃ formation in southwestern China was predominantly governed by NOx-limited conditions, whereas VOC-limited and transitional regimes prevailed in northeastern and northern core cities. Response curve range is the primary sensitivity regime discriminator, with VOC-limited/transitional ranges being larger than those in NOx-limited regimes.

Yet knowledge of how these contaminants move through food webs is lacking for many compounds, limiting our understanding of the potential ramifications. We conducted a systematic review following PRISMA guidelines to quantify global knowledge on trophic transfer of PPCPs. We extracted empirical data from 44 publications that observed field-based trophic transfer of PPCPs. We extracted or calculated trophic magnifications factors for 75 PPCPs and compiled a database of physicochemical properties of each PPCP. Over half of the studied compounds exhibited at least one instance of trophic magnification. Antimicrobials such as enrofloxacin and the sulfonamides were commonly shown to magnify through food webs. We found no global correlation of trophic magnification factor with bioconcentration factor, nor with physicochemical parameters typically used to predict bioaccumulation such as LogP, LogD, LogK_OA, and molecular weight. Our analysis highlights a high degree of variability in reported PPCP bioconcentrations and trophic magnifications among studies of the same class of PPCPs, suggesting that trophic magnification may be highly dependent on ecological context. This paper presents the most comprehensive review of the literature on trophic transfer of pharmaceuticals to date, with important implications for characterizing patterns among groups of compounds and highlighting knowledge gaps regarding ecosystems and PPCPs. The work underlines that field-derived empirical measurements of TMF for PPCPs are an important component of contaminant risk assessment and regulation.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"55 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145017672","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}

In waiting areas with interconnected spaces, complex airflow, unclear bioaerosol dispersion, and the limitations of traditional control methods pose major challenges. This study combined real-world experiments and numerical simulations to investigate the airborne transmission characteristics of pathogen-laden aerosols in a hospital waiting corridor. Serratia marcescens was used as a tracer bacterium to measure bioaerosol concentrations through release experiments. Computational Fluid Dynamics(CFD) has been used to analyze airflow characteristics in hospital corridor by Ω-vortex and air of age, and the improved Wells-Riley model was used to evaluate time-averaged exposure risk and identify high-risk zones under different conditions. The transport of bioaerosols within the waiting corridor is significantly influenced by its interaction with adjacent spaces. For instance, airflow from the main entrance can effectively reduce the overall deposition rate. However, opening the doors to consultation rooms diminishes the effectiveness of this entrance airflow, leading to an 8.14% increase in the corridor's deposition rate compared to the scenario with only the entrance open. Two control strategies were examined: increasing air changes per hour (ACH) and enhancing exhaust air pressure difference. Both approaches were found to lower mean indoor bioaerosol concentrations. Notably, increasing exhaust air pressure difference to the -3Pa can reduce the average concentration by up to 35.66% and lowered deposition across multiple zones (decreasing 9.27% in all zones). In contrast, raising ACH could worsen local deposition despite reducing airborne concentration because it can also increase deposition rate (10ACH, increasing 6.12%). The results demonstrate that airflow from adjacent spaces is a significant factor within the hospital waiting corridor and should not be overlooked. Furthermore, in corridors with mechanical ventilation, increasing the exhaust pressure differential is a more effective and practical strategy for bioaerosol control.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"26 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145007312","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}
