However, in contaminated areas, these values are often difficult to define due to the superposition of geogenic contributions and multiple historical anthropogenic inputs. Here, we propose an innovative approach in which magnetic separation is applied as a pretreatment prior to lead (Pb) and cadmium (Cd) stable isotope analyses to identify the geochemical background in polluted soils. Soils affected by historical smelting activities were collected at a highly contaminated site. The geochemical background was inferred from the characterization of the parent material and multivariate statistical analyses reported in previous studies, while potential pollution sources were identified through smelter-derived fly ashes and slags. Soil samples were subjected to magnetic separation using a wet high-intensity magnetic separator at different magnetic field intensities (10, 30, and 50%), aiming to concentrate anthropogenic particles in the magnetic fraction. Marked differences between magnetic and non-magnetic fractions were observed, particularly at the lowest magnetic intensity. At 10%, Pb in the non-magnetic fraction showed an isotopic signature consistent with the parent material (206Pb/204Pb = 18.43), whereas the magnetic fraction matched the pollution source (206Pb/204Pb = 17.97). Similarly, the magnetic fraction was enriched in lighter Cd isotopes (δ¹¹⁴Cd = 0.14 ± 0.02‰), consistent with fly ash signatures, while the non-magnetic fraction was heavier (δ¹¹⁴Cd = −0.34 ± 0.05‰), reflecting the geogenic background. Overall, our results demonstrate that magnetic separation constitutes an effective and relatively low-cost pre-treatment for disentangling geogenic and anthropogenic contributions in metal-contaminated soils.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"13 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2026-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147751513","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}

We investigated whether polycyclic aromatic hydrocarbons (PAHs) are detectable in the vaginal tract of female firefighters and whether these contaminants are linked to high-risk human papillomavirus (HPV) infection and vaginal microbiome alterations. In this cross-sectional study 49 female firefighters and 51 community controls self-collected vaginal swabs for analysis of 16 EPA-priority PAHs, high-risk HPV, and microbial composition. All 16 PAHs were detectable and median total PAHs were 3-fold higher in firefighters than controls (p<.0001). PAH burden increased with firefighting tenure showing a strong positive correlation between high- and low-molecular-weight congeners (r=0.85). High-risk HPV was detected in 12.2% of firefighters versus 3.9% of controls and was associated with higher PAH levels (p=0.02). Firefighters exhibited a microbiome shift characterized by increased relative abundance of Gardnerella (r=0.32 with total PAHs) and reduced Lactobacillus dominance. Detection of vaginal PAHs along with their associations with HPV and dysbiosis, suggests a previously unrecognized pathway by which occupational exposures may elevate cervical cancer risk. Targeted exposure reduction policies and vigilant gynecologic screening should be considered for this underserved workforce.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"22 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2026-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147755227","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 this study we conducted a molecular investigation on ureC gene expression of model Microbial-Induced Calcite Precipitation (MICP) bacterium Sporosarcina pasteurii during growth under increasing concentrations of hydrocarbon water extracts obtained from a coal tar polluted soil to ensure environmental relevance. Results indicated S. pasteurii ability to carry out ureolysis from low initial cell concentration (OD600, initial = 0.01). Flow cytometry showed insignificant differences in growth despite undergoing significant cell membrane damage at the highest hydrocarbon concentration. Quantification of ureC gene revealed a significant increase in urease transcription per unit cell with increasing hydrocarbon concentration, indicating higher urease synthesis to maintain similar ureolysis rates. We postulate this adaptation mechanism was in response to the nitrogen deficiency caused by intracellular urease inhibition by hydrocarbons. The temporal dynamics in ureC gene expression indicated urease transcription in S. pasteurii was inductive rather than constitutive. This gene up-regulation mechanism resulted in earlier ureolysis and achievement of environmental conditions favourable for calcium carbonate precipitation compared to the absence of hydrocarbons.

Conventional inhalation risk assessments frequently rely on mean deposition indices and simplified mechanical models, failing to reproduce ventilatory heterogeneity, thereby masking regional difference in aerosol deposition. To elucidate the correlation between regional airflow dynamics and tissue vulnerability, we developed an anatomically full-scale digital lung model that incorporates nonlinear compliance and gravity-driven pleural pressure gradients to simulate particle deposition during quiet, up-right breathing in healthy adults. Numerical simulations of aerosol particles (0.1–10 µm) over a complete respiratory cycle revealed a distinct gravity-dependent heterogenous deposition pattern: The highest deposition intensity was observed in the right lower lobe and left lower lobe, while the lowest occurred in the right upper lobe. Three deposition hotspots were identified: two in the right lower lobe (0.53%/m2) and left lower lobe (0.51%/m2), spanning generations G21-G23 and enriched with particles of 3 µm in diameter, and one in the right lower lobe (0.48%/m2), spanning generations G7-G10 and enriched with particles of 10 µm in diameter. Additionally, we use wielding fume as an example to demonstrate how to quantitatively calculate the regional surface deposition density and exposure time required to reach cytotoxicity thresholds, highlighting the model’s ability to translate regional deposition patterns into biologically meaningful risk metrics. In conclusion, our full-scale digital lung model replicates human-specific airway branching and ventilation dynamics, offering a non-invasive digital platform for temporospatial evaluation of inhalation risks from hazardous aerosol.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"29 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2026-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147709167","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 analyzed 3,283 sediment samples from Hong Kong waters (1987-2024) to characterize four decades of heavy metal contamination dynamics. Three distinct contamination peaks were identified (1988-1991, 1998-2003, 2020-2023), with the most recent period showing astonishing increases: arsenic (+137%), nickel (+144%), lead (+76%), and zinc reaching unprecedented levels (628.0 mg/kg). Contamination hotspots concentrated in semi-enclosed waters (Deep Bay, Victoria Harbour, Junk Bay) where restricted circulation enhances accumulation. Strong Fe-As coupling (r = 0.504) indicates Fe (oxyhydr)oxides as the dominant arsenic carrier phase. Ecological risk assessment revealed that Cu, Ni, Zn, and Pb exceeded PEL thresholds during 2020-2023, with mean ERM quotient (0.851) indicating moderate-to-high toxicity probability. Source apportionment identified antifouling paints as an emerging threat, with contributions increasing 96% following the 2008 tributyltin ban—an unintended consequence of regulatory substitution. These findings demonstrate that heavy metal resurgence represents an underappreciated environmental threat requiring renewed monitoring attention and international regulatory coordination in coastal megacities.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"29 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2026-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147732340","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}

Adsorbents can retain and remove CEC; however, the widespread presence of natural organic matter (NOM) complicates such adsorption processes. The functional groups present in ionizable CEC, NOM, and adsorbent influence charge characteristics and adsorption affinity, with their effects varying according to pH conditions. Hydrophobic and electrostatic interactions are considered main driving forces. However, these two interactions cannot fully explain 1) the binding of ionizable CEC to adsorbents at specific environmental pHs and 2) the self-aggregation of NOM molecules to supramolecular aggregates. Charge-assisted hydrogen bond (CAHB) is a three-center-four-electron, low-barrier hydrogen bond with considerable covalent nature. Pignatello J.J., his contemporaries, and his colleagues demonstrated that the formation of CAHBs 1) facilitates adsorption characteristics at CAHB-favorable pHs, 2) increases pH by taking up protons from water, 3) shifts pKa upward, 4) contributes to homoconjugation of carboxylates, 5) affects surface charge of dissolved organic matter aggregates, and 6) holds NOM molecules together. This review article serves as a summary of CAHB papers with significant environmental implications, and as a critical evaluation of how CAHB influences the fate and transport of representative, ionizable CEC, such as (aged) microplastics and nanoplastics, per- and polyfluoroalkyl substances (PFAS), pharmaceuticals, pesticides, etc. This article also discusses how CAHB plays a role in the structure of NOM. Discussions herein will inform the community about the activity, reactivity, and treatability of ionizable CEC.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"196 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2026-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147682065","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}

The results indicated that PFASs were widespread in the soil, with total concentrations ranging from 40.7 to 72.0 ng/g. The average concentration of PFASs followed the order: traditional PFASs > emerging PFASs, with short-chain PFCAs (C≤8) being predominant. Significant accumulation of PFASs was observed in the edible portions of vegetables, particularly in leafy greens, which exhibited the highest bioaccumulation capacity. In rice, PFASs concentrations ranged from 0.329 to 11.3 ng/g dw, and short-chain PFCAs were also the dominant compounds. Residents were stratified by age and gender to estimate their daily exposure doses (EDI), which ranged from 70.5 to 136 ng/kg bw/d. Notably, Monte Carlo simulations revealed that a substantial proportion of local residents exceeded the tolerable daily intake levels for PFOA and PFOS, suggesting potential health risks associated with long-term exposure. This study demonstrated that the FIP served as a direct and significant source of PFASs contamination in the local agricultural ecosystem, resulting in non-occupational human exposure.
