We present the first long-term (2010–2024) observation of atmospheric MP_2.5 in Beijing, quantified with pyrolysis–gas chromatography / mass spectrometry. Our investigation of type-specific trends and driving factors revealed an overall increasing trend in MP_2.5 concentration, with an average level of 264 ng/m³ and a peak of 417.6 ng/m³ in 2021. The distinct trends of MP_2.5 and PM_2.5 concentrations suggest that their major sources differ, necessitating different regulation measures for each. PVC (polyvinyl chloride), PS (polystyrene), PP (polypropylene), PE (polyethylene), and PA66 (polyamide 66) are the predominant types of MP_2.5, differing markedly from the pattern in dustfall or total suspended particulate matter. PS, PP, and PP correlated positively with express delivery volume and total retail sales of consumer goods, implicating packaging material as a potential major source. PA66 and PVC, which are widely used in disposable medical supplies such as protective suits, responded sensitively to the COVID-19 pandemic. Our findings reveal that socioeconomic activities strongly influence the long-term evolution of MP_2.5 patterns, and provide a scientific basis for related risk assessments","PeriodicalId":308,"journal":{"name":"Environment International","volume":"31 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2026-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146129656","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 examined associations between wildfire-specific PM_2.5 exposures and ASD risk in California births, considering exposure timing, intensity, and background air pollution.<h3>Methods</h3>We analyzed 8.6 million births in California from 2001 to 2019, linking records to ASD diagnoses in California Department of Developmental Services records through 2022. Wildfire-related PM_2.5 exposures, including biomass burning and wildland-urban-interface (WUI) source tracers, were estimated for preconception, pregnancy, and post-pregnancy periods. Exposure metrics included continuous, percentile-based, and episode-based indicators. Logistic regression was used to estimate odds ratios, adjusting for sociodemographic covariates. Stratified analyses were conducted by background PM_2.5, urbanicity, diagnostic era, and sex.<h3>Results</h3>Continuous wildfire-specific exposures during the pregnancy-period were weakly associated with ASD, but stronger effects emerged at high exposure percentiles and during intense wildfire episodes (≥35 µg/m³). Associations were most pronounced among children in the lowest quartile of prenatal background PM_2.5, with odds of ASD increasing by 50% for those in the &gt; 90th percentile of wildfire PM_2.5 during pregnancy. WUI-related PM_2.5 was associated with ASD in metro areas, suggesting unique toxicity. Effects were stronger in non-metro regions, with the exception of WUI-related PM_2.5, for births occurring after the implementation of DSM-5, and in White children. Sex differences were minimal, but showed stronger effect estimates for WUI-related PM_2.5 and high exposure episodes for males.<h3>Conclusion</h3>Wildfire smoke exposure during pregnancy may increase ASD risk, particularly in low background air pollution and rural settings. High-intensity wildfire events were most strongly associated with ASD, underscoring the need for targeted policies, such as vegetation management, land use planning, and indoor filtration upgrades in the context of increasing wildfire frequency and severity.","PeriodicalId":308,"journal":{"name":"Environment International","volume":"1 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2026-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146121996","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}

Ingestion of U-contaminated water and food results in bioaccumulation, primarily within the kidneys and bones, leading to severe nephrotoxicity and potential long-term health consequences. Addressing this challenge, we present a novel bio-intervention strategy leveraging a genetically engineered probiotic for the prevention of U absorption at its primary entry point—the gastrointestinal tract. We engineered<!-- --> <em>Escherichia coli</em> <em>Nissle</em> 1917 (EcN) to express a high-affinity uranyl-binding protein (U09), generating the EcN-U strain. EcN-U sequestered soluble uranyl ions (UO₂²⁺) within the gut lumen via selective and efficient binding, leading to fecal excretion and prevention of systemic absorption. In a murine model of acute<!-- --> <!-- -->UO₂²⁺ exposure, EcN-U pre-treatment significantly enhanced survival rates. Furthermore, in chronic exposure models utilizing mice, rats, and beagle dogs, EcN-U pre-treatment demonstrably reduced U accumulation in target organs by approximately 80%.

Our findings establish engineered probiotics as a pragmatic and potent strategy for environmental health protection, offering a proactive and viable solution for public health risk mitigation associated with waterborne uranium contamination.","PeriodicalId":308,"journal":{"name":"Environment International","volume":"39 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2026-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146129657","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}
