While most studies focus on the toxicity of OPPs to humans and animals, their roles in ARG dissemination remain largely unexplored. In this study, we investigate the effects and involved molecular mechanisms of environmentally relevant concentrations of malathion and dimethoate, two representative OPPs, on plasmid-mediated conjugal transfer. By detecting reactive oxygen species (ROS) production and cell membrane permeability, we gained insights into the underlying processes. Furthermore, we substantiated the role of ROS and cell membrane permeability in plasmid-mediated conjugative transfer through the analysis of relevant antioxidant enzyme activities, cell membrane-related indices, and RNA sequences. Additionally, our examination of proton motive force and adenosine triphosphate content provided evidence that OPPs create conditions conducive to plasmid-mediated conjugative transfer from an energetic perspective. The findings of the present study highlight the potential risk of OPPs in promoting ARG spread, which could ultimately provide new theoretical support and direction for future research on the impacts of pesticides on ARG propagation.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"38 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142992449","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}

Cement industry is not considered as a primary contributor to persistent organic pollutants like polychlorinated dibenzo-p-dioxins and furans (PCDD/Fs), owing to its extremely low emission factor. However, knowledge on the previously unrecognized chemicals that may possess higher emission factors from cement industry is lacking. In this study, non-target screening of pollutants from cement industries were conducted using gas chromatography-quadrupole time-of-flight mass spectrometry. Priority pollutants from cement industry were identified. Alkylated polycyclic aromatic hydrocarbons and chlorobenzene were noteworthy pollutants from cement industry. By comparing the toxicity data and semi-quantitative of the pollutants, 9 chemical compounds, including 1-Methylphenanthrene, were identified as priority pollutants. The emission factors of these selected pollutants from cement industries were about 3-6 orders higher than PCDD/Fs, suggesting a potentially high risk of emission. The nationwide emission estimation indicates a significant release of approximately 300 kilograms of 1-Methylphenanthrene emanating from the cement industry, necessitating heightened attention. The results are helpful for comprehensive risk assessment of organic pollutants from cement industry.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"18 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142992451","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 neurotoxicological effects and mechanisms of CS on Alzheimer's disease (AD) progression remain unclear. We found that CS accelerated the progression of AD, including increasing β-amyloid (Aβ) plaque deposition and exacerbating cognitive decline. Mechanistically, CS exposure increased the levels of NOD-like receptor protein 3 (NLRP3), which impaired autophagic flux in microglia by activating the mammalian target of rapamycin (mTOR) signal. Metabolomics analysis revealed an upregulation of lactate levels and an increase in global protein lysine lactylation in the brain tissue of CS-exposed AD-transgenic mice. Immunoprecipitation-Mass Spectrometry and chromatin immunoprecipitation assays demonstrated that CS elevates H4K12 lactylation (H4K12la) levels, which accumulate at the promoter region of NLRP3, leading to the activation of its transcription. Via inhibiting lactate or NLRP3 activation, oxamate and MCC950 alleviates these CS-induced effects. Therefore, our data suggest that the CS-induced increase in lactate levels triggers NLRP3 transcriptional activation through H4K12la, which subsequently leads to mTOR-mediated autophagy dysfunction in microglia, promoting microglial activation and resulting in Aβ plaque accumulation in AD-transgenic mice. This provides a new mechanism and potential therapeutic target for AD associated with environmental factors.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"18 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142992459","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, PLA is challenging to fully degrade and can easily become microplastics (MPs) in surface water, a process accompanied by aging. This study found that aged PLA (APLA) MPs exhibited increased surface roughness, decreased surface potential, and more oxygen-containing functional groups compared to PLA. Acute exposure to PLA/APLA in zebrafish larvae resulted in sluggish behavior and inhibited neuronal development. Chronic exposure to PLA/APLA in adult zebrafish led to reduced exploratory behavior, poor memory, increased aggression, and neuron loss. Overall, PLA/APLA induced dose-dependent neurotoxicity, with APLA exhibiting greater toxicity than PLA, potentially due to its higher rate of uptake. Additionally, exposure to PLA/APLA led to thinning of the intestinal wall, shortening of villi, and suppression of intestinal neurotransmitter levels, accompanied by alterations in microbial abundance and gut dysbiosis. Meanwhile, supplementation with bile acid, considered as the key regulator in the gut-brain axis, significantly mitigated the neurotoxicity induced by PLA/APLA. These findings confirm that PLA/APLA MPs indeed elicit neurotoxicity via the gut-brain axis and provide scientific evidence for targeted environmental interventions to minimize the adverse ecological impacts of biodegradable MPs.","PeriodicalId":361,"journal":{"name":"Journal of Hazardous Materials","volume":"31 1","pages":""},"PeriodicalIF":13.6,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142990866","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}

Our results demonstrate that short-term NP exposure does not significantly affect the generation or neutralizing capacity of antibodies against VSV, nor the cellular responses directed against LCMV.
