Despite growing evidence of microbial interactions with plastics, the mechanistic basis and extent of biofilm-mediated polymer deterioration remain poorly constrained. Here, we investigate the capacity of mangrove-derived bacterial consortia to initiate early-stage degradation of major synthetic polymers (PET, PS, LDPE, HDPE, and PP) under controlled laboratory conditions. Over a 120-day incubation under controlled laboratory conditions, consortium-exposed polymers exhibited differential mass loss, surface erosion, and mechanical weakening, with PS 20.14% and PET 8.33% showing the highest susceptibility. Integrated surface and molecular analyses using confocal laser scanning microscopy, atomic force microscopy, scanning electron microscopy energy dispersive X-ray spectroscopy, and Fourier-transform infrared spectroscopy revealed extensive biofilm formation, nanoscale pitting, oxidative functional group incorporation, and localized polymer chain modification. Tensile testing further demonstrated reductions in mechanical integrity consistent with surface-driven structural weakening. First-order kinetic fits were applied to gravimetric data to provide comparative, non-predictive estimates of degradation dynamics across polymer types. This study provides quantitative and mechanistic evidence that environmentally adapted microbial consortia can promote biofilm-driven surface depolymerization, highlighting mangrove sediments as underexplored reservoirs of plastic-interacting microbes. These findings advance current understanding of early-stage plastic biodegradation and inform future strategies for biotechnological intervention in microplastic-polluted environments.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"52 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2026-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147493118","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}

Using catalytic oxidation of gaseous elemental mercury (Hg⁰) from coal-fired flue gas as a probe, we establish a Sabatier relationship for O₂-mediated E-R pathways over metal-incorporated graphitic carbon nitride (M-CN) catalysts. Density functional theory calculations reveal that the overall reaction rate is jointly limited by Hg-assisted O-O bond cleavage and the desorption of oxidized mercury species (HgO)_x. Correlating catalytic activity with atomic oxygen adsorption energies identifies Co-CN as optimally positioned near the apex of the Sabatier volcano among ten M-CN catalysts. Guided by this mechanistic insight, a Co-CN catalyst is rationally synthesized via a novel stepwise strategy and exhibits near-complete Hg⁰ removal at 280 ºC, strong tolerance toward high SO₂ concentrations, and a synergistic promotional effect of NO, while maintaining an Hg⁰ removal efficiency of 85.13% after eight thermal regeneration cycles, demonstrating excellent operational stability and recyclability. Long-term dynamic tests reveal that Co-CN reaches a stable balance between Hg⁰ oxidation and product desorption after ~15<!-- --> <!-- -->h, delivering a Hg⁰ removal capacity of 0.94<!-- --> <!-- -->mg∙g^-1, superior to most reported carbon-based catalysts. Mechanistic validation confirms that Hg⁰ oxidation proceeds via surface-activated oxygen species on Co-N sites, while gradual accumulation of surface-bound (HgO)_x and partial Co-N oxidation dictate long-term performance decay under oxygen-rich conditions. This work establishes a fundamental framework for designing Sabatier optimal catalysts in O₂-mediated E-R models for environmental remediation.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"17 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2026-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147493117","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 first demonstrates the manganese(II) sulfate (MnSO₄) mitigates Cd and As co-accumulation and co-toxicity in rice, and elucidates the underlying mechanisms by employing integrated ionomic, transcriptomic and metabolomic analyses. Application of moderate to high doses of MnSO₄ in pot experiments increased brown rice yield by 208.78-428.60% while reducing Cd and As content by 4.89-21.98% and 60.65-81.73%, respectively. MnSO₄ mediates Cd distribution through direct competitive antagonism, whereas As sequestration is governed by more complex and indirect regulatory pathways. The MnSO₄ amendment also orchestrates a remodeling of the mineral element network by regulating key genes and metal transporters. This mechanism ultimately limits the accumulation of Cd and As in the grain via distinct pathways: by hindering root to brown rice Cd translocation and inhibiting stem/leaf to brown rice As translocation. Transcriptomic and metabolomic analysis further revealed that Mn alleviates combined Cd-As stress by downregulating key pathways involved in lipid peroxidation and sphingolipid metabolism, thereby enhancing cellular membrane stability. Collectively, MnSO₄ integrates transporter regulation, ionomic reconfiguration, and metabolic adaptation to alleviate Cd-As co-stress in rice. Our findings provide a effective approach to ensure rice safety in contaminated regions.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"50 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2026-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147493041","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 examined the influence of co-contamination with imidacloprid and copper on antibiotic resistance genes (ARGs), mobile genetic elements (MGEs), and microbial functional traits within soil and plastisphere microhabitats under flooding conditions. Pollutant exposure at environmentally relevant concentrations promoted ARG and MGE enrichment, with stronger effects as pollutant number increased. Under combined pollution, ARG abundance increased up to 5.59- and 2.42-fold in the plastisphere and soil under non-flooded conditions, and 2.62- and 2.75-fold under flooding. However, flooding reduced ARG abundance under combined pollution to 0.31- and 0.64-fold relative to non-flooded conditions. Nevertheless, the plastisphere maintained consistently stronger ARG–MGE associations. Functional trait analyses revealed that plastisphere microbes possessed higher GC content, smaller genomes, and faster growth rates than their soil counterparts, consistent with the Black Queen Hypothesis. Lower GC content and enhanced anaerobic metabolism were associated with greater ARG abundance, highlighting trait-mediated enrichment of ARGs in plastisphere biofilm habitats. Structural equation modeling further identified flooding-driven anaerobic respiration, microbial community composition, pollutant number, and MGE abundance as key determinants of ARG dynamics in the plastisphere, whereas ARG abundance in soil was primarily influenced by pollutant number and community composition. Collectively, these findings identify the plastisphere as a distinct reservoir of antibiotic resistance shaped by flooding and multiple chemical stressors, and emphasize the role of microbial functional traits in mediating ARG enrichment.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"7 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2026-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147492493","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}
