However, low efficiency limits the application of biological methods for antibiotics removal. Herein, a mixed culture of halotolerant fungi-bacteria was used for treatment of saline wastewater containing tetracycline (TC). Furthermore, static magnetic field (SMF) was used to increase TC removal. The study examined the effectiveness of SMF in removing antibiotics from saline wastewater and the associated risk of ARGs transmission. The results demonstrated that the application of a 40 mT SMF significantly improved the TC removal efficiency by 37.09%, compared to the control (SMF=0) The TC was mainly removed through biodegradation and adsorption. In biodegradation, SMF enhanced electron transport system activity, and activities of lignin-degrading enzymes which led to higher TC biodegradation. The activity of lactate dehydrogenase and malondialdehyde decreased, lowering the damage of microbial cell membranes by TC. During the adsorption process, higher generation of extracellular polymeric substances was observed under SMF, which caused an increase in TC removal via adsorption. Microbial community analysis revealed that SMF facilitated the enrichment of TC-degrading microorganisms. Under SMF, vertical gene transfer of ARGs increased, while horizontal gene transfer risk decreased due to a reduction in mobile genetic elements (intl1) abundance. This study demonstrates that SMF is a promising strategy for enhancing TC removal efficiency, providing a basis for improved antibiotic wastewater management.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"216 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143776098","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, direct experimental evidence demonstrating their toxicity on the human liver remains limited. Consequently, this study aimed to extrapolate the 8C-PFAS liver toxicity mechanisms by leveraging omics data to integrate mouse and human findings. Through integration analyses of nine datasets (one human, six murine, and two rat), we identified 199 genes with known biological functions that are commonly affected by 8C-PFAS across species. We delineated a comprehensive regulatory network of 8C-PFAS toxicity, demonstrating that 8C-PFAS may trigger fatty liver disease by up-regulating CD36 and PPARα pathway; dysregulate xenobiotic metabolism by disrupting CAR and CYP family genes; and induce cancer by dysregulating WNT, TGFβ, FGF21, and P53 pathways. We also identified ATF3, EGR1, ESR1, NFATC4, SNAI2, TP53, and EZH2 as transcriptionally regulated by 8C-PFAS, along with PPARα, RXRα, FGFR1, TCF3, and SMAD3 as potentially functionally impacted. Collectively, these factors account for over 90% of 8C-PFAS-affected key genes. This study not only developed a novel method for extrapolating human toxicity risks by integrating scattered toxicity evidence based on transcriptomics data, but also proposes new mechanisms by which 8C-PFAS contributes to fatty liver disease and cancer.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"58 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143776097","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, OPE contamination characteristics and microbial degradation mechanisms in agricultural soils remain poorly understood. This study investigated agricultural soils from the riparian zone of the Anning River Basin in southwest China. The concentrations of 12 OPEs were determined using gas chromatography–tandem mass spectrometry. The results revealed that the total OPE concentration was moderate, with triethyl phosphate being the most abundant compound. Metagenomic techniques and Bayesian linear regression analysis were employed in combination with the Kyoto Encyclopedia of Genes and Genomes database to identify potential degradation pathways for triethyl phosphate and tris (2-chloroethyl) phosphate. The phoA, phoB, phoD, and glpQ genes, which encode phosphatases, catalyze ester bond cleavage, thereby facilitating the degradation of OPEs. Further microbial interaction network analysis identified core OPE-degrading microorganisms, including Pimelobacter simplex, Nocardioides sp. JS614, Nocardioides daphniae, and Methylocystis heyeri. Additionally, neutral community models indicated that environmental selection drives microbial community structure. In conclusion, this study provides an in-depth understanding of OPE contamination and its microbial degradation mechanisms in agricultural soils, offering theoretical insights for pollution management and remediation strategies.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"18 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143776099","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 evaluated the degradation of C7 HFPO-TA and co-existing PFHxA in AOPs, mainly focusing on the molecular structure effect on the chemical affinity with different reactive species (RSs). The results showed that >99.9% C7 HFPO-TA and PFHxA could be decomposed after 480 min in UV/PS, significantly outperforming UV/H2O2 (<10%), as the result of the synergistic effect of radical/non-radical (SO4•-/HSO4•, O2•-, HO•, 1O2) and chain reactions. The degradation mechanism of C7 HFPO-TA was primarily governed by the DHEH mechanism, which facilitated radical chain reactions and resulted in the formation of a new perfluoroalkyl ester intermediate (C6F12O3), as optimized by Transition State theory. The degradation of five HFPO and three PFCA was highly dependent on their molecular structures. Degradation kinetics and DFT calculations demonstrated the longer branched fluorocarbon chain could diminish the steric hindrance of α-CF3 in HFPO and made the electron distribution more flexible for the reaction with the RSs. The comprehensive analysis of degradation kinetics, theoretical calculations and intermediates analysis elucidated the transformation mechanisms of C7 HFPO-TA and PFHxA in UV/PS.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"183 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143776093","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 abundance of functional genes involved in nitrogen and organic matter metabolism, including GDH2, ACSS1_2, and mqo, was significantly influenced by IBU stress, thereby affecting overall system performance. Additionally, several degradation by-products of IBU which had lower toxicity were identified, suggesting the effective biodegradation within the MBGS system.

Metabolome analysis revealed altered stress responses and reprogrammed metabolic pathways, particularly in lipid and carbohydrate metabolism, which correlated strongly with gut microbiota changes. Overall, we demonstrated the biodegradation of PS by S. litura and S. frugiperda for the first time, and proposed a plausible degradation mechanism mediated by gut microbiota, illustrating both the host and gut microbiomes contributed to PS biodegradation.

In addition, this study was the first to use the probabilistic species sensitivity distribution (pSSD) approach to deduce the predicted no-effect concentrations of major fungicides as terrestrial safety thresholds.

Various organisms have exhibited alterations in behavior or metabolic activities following exposure to microplastics (MPs). Mosquitoes, as crucial disease vectors, are particularly susceptible MPs exposure in the environment. Recent studies have demonstrated that MPs ingested by mosquitoes can be detected in vivo, potentially being transmitted during their different life cycles. However, it remains unclear whether MPs in vivo could affect mosquito infection with arboviruses. In this study, we identified that the physical adsorption effect of MPs is also effective against arboviruses, enabling the adsorption of Zika virus particles onto their surfaces. We established an exposure model by feeding adult Aedes albopictus (Skuse, 1895) (Diptera: Culicidae) with 1 μm MPs at concentrations of 5 and 50 μg/mL in 8% sucrose solution. The transmission rate of ZIKV and population transmission rate in the laboratorial Ae. albopictus exposure model began to decrease from day 7, showing statistically significant differences compared to the control group on days 10 and 14 (**, p < 0.01), significantly affecting their vector efficiency. This phenomenon is not solely dependent on the physical adsorption of MPs to arboviruses. Transcriptome analysis indicated that exposure to MPs influenced the expression levels of genes associated with mosquito virus infection, altering the function of relevant pathways, which consequently reduces their capability to transmit arbovirus. These findings suggest that exposure to MPs significantly affects the vector efficiency of mosquitoes, providing novel perspectives for the ecological risk assessment of MPs.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"8 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766810","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}
