In this study, we explored aerosol dispersion from sequential coughs using large eddy simulation (LES), validated by particle image velocimetry (PIV) experiments. Two types of sequential coughs were investigated and compared to a single cough: one with two identical peak velocities of 10 m/s (10-10 m/s), and another with peak velocities of 10 m/s followed by 5 m/s (10-5 m/s). In the 10-10 m/s scenario, the second cough merged with the first at 2 s and 1.2 m, resulting in enhanced aerosol dispersion compared to a single cough. In contrast, in the 10-5 m/s scenario, the second cough, due to its lower velocity, caught up with the first at 8 s and 1.6 m. The 10-10 m/s scenario demonstrated a stronger capacity for dispersing aerosols than both the 10-5 m/s scenario and the single cough. Sequential coughs increased infection risk by 2-4 times across the full range and required an average increase of 0.5 m in social distancing, due to the enhanced aerosol dispersion and emission of aerosols. These findings improve our understanding of aerosol transmission and inform social distancing guidelines in indoor environments.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"105 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145183081","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}

By mimicking water contamination and using zebrafish larvae, we tested the hypothesis that low environmentally relevant concentrations of BPS, BPF, and BPAF, compared to BPA, elicit physiological and molecular modifications. We verified lethal doses (LD₅₀; BPAF > BPF > BPA > BPS) using an OECD-compliant protocol and reported the absence of morphological and muscle abnormalities, and hatching delays below the LD₅₀ at 5 days post-fertilization (dpf). We identified the lowest bisphenol exposure levels that provoke the most significant motor-swimming changes (100 ng/L BPS, 10 ng/L BPF, 100 ng/L BPAF, and 100 ng/L BPA). We asked whether the observed motor phenotype at low bisphenol levels could be underpinned by heart-brain electrophysiological adaptations. Using in vivo optical mapping, we found increased high-frequency, low-amplitude brain activity and, in the cases of BPF and BPAF, bradycardia. Within these specific low-exposure settings, transcriptomics identified eight genes involved in heart-brain functions, homeostatic and immune regulation, that were down-regulated by each bisphenol, namely anxa1c, vwa10.1, zgc:172053, grna.2, ehf, gna14, ca15c, atp1a1a.5.

However, its surface oxide layer severely restricts interfacial electron transfer, resulting in low decontamination efficiency. Herein, a tannic acid-modified mZVI (TA-ZVI) was developed using ball milling. The modified material exhibited excellent Cr(VI) removal efficiency (98.2% in 2 min) due to the abundant presence of surface hydroxyl groups. The results of electrochemical analysis demonstrated that the hydroxyl groups increased the electron density and conductivity of the material surface, accelerated the electron transfer, and led to the formation of low and uniform surface potential on the material surface. The hydroxylated interface facilitated in situ Fe(II) generation and release to the solution. The hydroxyl groups then complexed with Fe(II) in the solution to form =FeOFe(II)+, which facilitated protonic reactions and led to the formation of =FeOH2+. Density functional theory (DFT) calculation proved that the reaction energy barrier of =FeOFe(II)+ for Cr(VI) was much smaller than that of Fe(II) in the solution. Moreover, the surface hydroxyl species (=FeOH and =FeOH2+) directly participated in Cr(VI) removal through synergistic adsorption-reduction pathways, thereby contributing significantly to the overall removal.

This study first detailed the effects of two Clean Air Plans implemented during 2012 to 2020 on the air pollutant emissions of Chinese CFIBs based on the establishment of an up-to-date emission inventory covering primary air pollutant species. Specifically, we analysed the spatiotemporal heterogeneity of air pollutant reductions, quantified the measure-specific emission reductions, and further investigated the synergistic effects for hazardous trace elements (HTEs) in the base years 2012, 2017 and 2020. Results showed that national emission reductions in PM, M2.5, SO2, NOx, and HTEs (sum of Hg, As, Cd, Cr, and Pb) were 3678.8 kt, 942.0 kt, 6672.5 kt, 1446.1 kt, and 5981.7 t from 2012 to 2020, respectively, with the largest reductions occurred in the period 2012-2017 (66.4–90.5%). East China, Northeast China, and South-Central China were the most beneficial regions to achieve emission reductions of air pollutants, and their share of the contribution to emission reductions ranged from 80.1% to 86.9%. The measure of phase-out boilers resulted in the highest reductions in air pollutant emissions from 2012 to 2017 with the share of 58.7–66.3% over the entire period, while its contribution was weakened by the upgrading of air pollution control devices during 2017-2020. The synergistic effect of NOx on HTEs was weaker than that of PM, PM2.5, and SO2 with the lowest cross-elasticity coefficient, and the degree of synergistic effects also exhibited stage-specific heterogeneity.

Given the inconsistent nitrogen stressor–response relationships within river microbiota, this paper integrated a hydrological model with microbial analyses to evaluate the legacy effects of nitrogen pollution pattern changes on riverine microbiomes. Compared with point sources, non-point sources generated stronger material legacies (legacy nitrogen contributed up to 65.84% to current river nitrogen inputs) and stronger information legacies (species life-history traits contributed up to 73.93% to current microbial composition). We also documented a positive relation between these two types of legacies. Besides, microbial taxonomic and functional divergence between different pollution sources was amplified when pollution regimes remained consistent across seasons. Specifically, streams with a longstanding history of agricultural dominance exhibited the highest microbial taxonomic diversity but the weakest nitrification, dissimilatory nitrate reduction to ammonium, and denitrification capacities. Conversely, reaches with a long-term history of point-source dominance showed the lowest α-diversity but the strongest nitrogen-cycling potential. Further, an alteration of microbial stable state, which refers to a sudden and obvious shift in microbial ecosystems, was more likely to occur in rivers with contrasting seasonal pollution patterns. The highest probability of state shifts (41.7%) occurred where pollution patterns shifted from agricultural contamination (wet season) to rural domestic wastewater (dry season). Our findings highlight the need to incorporate legacy effects from pollution source changes into river remediation strategies to improve predictions and management of real-time ecosystem responses to environmental stressors.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"67 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145182873","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, the underlying pathways and mechanisms remain unclear. To address this knowledge gap, we employed a multi-omics approach combining experimental and epidemiological investigations. In the mouse model, untargeted metabolomics profiling revealed niacinamide (NAM) metabolism as the most significantly altered pathway in both maternal serum and placenta following BaP exposure. Mechanistically, BaP exposure reduced nicotinamide adenine dinucleotide (NAD+) synthesis while increasing its catabolism through activation of poly (ADP-ribose) polymerase 1 (PARP1) in placental tissue. Subsequent transcriptomic analysis showed that BaP-induced NAD+ depletion led to sirtuin 1 (SIRT1) suppression and consequent exacerbation of the NF-κB-mediated inflammatory response. These experimental findings were substantiated in human populations through targeted metabolomic analysis of a Chinese birth cohort, where significant NAM metabolic disturbances were observed in women with high BaP exposure experiencing preterm delivery. Our study provides novel mechanistic evidence that BaP-induced dysregulation of NAM metabolism mediates adverse birth outcomes through NAD+ deficiency and subsequent inflammatory response. These findings not only identify potential therapeutic targets but also highlight the urgent need for evidence-based environmental policy interventions and nutritional supplementation strategies to protect maternal-fetal health in high-risk populations.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"3 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145182862","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}
