Policy impacts on under-studied PFAS and on predictors of PFAS exposure remain unknown.<h3>Objective</h3>To assess changes in population-levels and exposure predictors of 10 PFAS in the Boston Birth Cohort (BBC) by Stewardship timelines.<h3>Materials and Methods</h3>In 1,288 BBC mothers who delivered 1999–2016, the current study focused on 10 PFAS in plasma samples collected 24–72 h postpartum. We estimated PFAS percent differences (%Δ), stratified by the Stewardship timelines. We evaluated predictors related to sources, vulnerability, blood-loss, and diet during pregnancy.<h3>Results</h3>The majority of participants were Black (65 %); 8 PFAS were commonly detected (>85 %). PFOS, PFOA, PFHxS, PFHpS, and Me-PFOSA-AcOH decreased by up to 88 % during PFOA reduction-period (2006–2009) or elimination-period (2010–2016) compared to pre-policy (1999–2005), regardless of race/ethnicity; PFNA, PFUnA, PFDeA, PFDoA, and GenX increased by up to 104 % among non-White mothers. PFAS were up to 148 % higher in mothers who frequently consumed shellfish or fish or vegetables, worked, owned pet(s), or had wall-to-wall carpet, with stronger associations post-policy for shellfish, fish, and working. PFAS were up to 36 % lower in mothers who had cesarean-section, took vitamin supplements, or lived overseas during pregnancy, with weaker associations post-policy for delivery type and country of residence.<h3>Conclusion</h3>Chemical policies can be effective at reducing PFAS exposures at the population-level, although the beneficial effects may not be equal across population-subgroups and could increase unregulated chemical exposures. Fish and vegetable consumption and occupational status were consistently associated with higher levels, while patterns of other predictors changed over time.","PeriodicalId":308,"journal":{"name":"Environment International","volume":"86 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145226740","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}

To address this knowledge gap, a 16-year field experiment assessed the effects of chicken manure (CM), sewage sludge composts (SSC), and domestic waste composts (DWC) on the accumulation, speciation, and bioavailability of eight HMs in a soil-maize system. The results showed that continuous application of CM, SSC, and DWC at 6 t ha<sup>−1</sup> increased soil concentrations of Cd by 20–38 %, Cr by 8–16 %, Cu by 9–21 %, Zn by 17–37 %, and Hg by 82–350 % compared to control or chemical fertilizer treatments, with SSC showing the highest Hg accumulation (306–350 % increase). A moderate ecological risk was observed in SSC-treated plots, while other treatments posed low ecological risks. Organic fertilizer application promoted the HM stabilization: e.g. the proportion of stable fraction for Cd increased from 64 to 65–70 % under organic treatments. Such stabilization reduced bioaccumulation factors of Hg, Cd, and Zn by 42–78 %, resulting in no significant increase in HM concentrations in maize grains or health risks. Safe application durations are first estimated as 117 and 131 years for CM and SSC application (limited by Zn), respectively, and theoretically unlimited for DWC. The study concludes that stabilization of HM speciation and regulated application rates of organic fertilizers can decouple total HM accumulation from ecological and health risks. These findings provide practical guidance for the sustainable recycling of organic waste resources while ensuring environmental and food safety.","PeriodicalId":308,"journal":{"name":"Environment International","volume":"100 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145226729","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 origins and transmission mechanisms of PGPB and their associated heavy metal resistance genes (MRGs) in plants remain unclear. To fill this knowledge gap, we collected rice and related environmental samples from heavy metal-contaminated paddy fields. The microbial DNA was recovered from these rice and environmental samples and then analyzed using shotgun metagenomics at the metagenome-assembled genomes (MAGs) level. As a result, 805 MRG-PGPB combinations were detected in rice tissues and related environments under heavy metal contamination conditions. Core MRG-PGPB combinations shared across seed-rice (42.46%) and environment-rice (13.34%) interfaces collectively constituted 55.8% of the detected combinations, demonstrating that environmental translocation and seed-borne vertical transmission jointly drive over half of MRG-PGPB colonization in rice systems. Subsequent source-tracking analysis indicated that PGPBs present in rice primarily originated from seeds, with a substantial proportion also attributed to translocation within rice tissues. Phylogenetic analysis of dominant MRGs further demonstrated the seed-borne vertical transmission of MRGs-PGPB, while simultaneously elucidating that MRGs harbored by PGPB in rice could also be acquired via horizontal gene transfer (HGT) from environmental or seed-borne MRG-PGPB, particularly from atmospheric microbes such as <em>Methylophilus</em> and <em>Serratia</em>. These findings provide valuable insights into harnessing PGPB to enhance rice resilience against heavy metal contamination, thereby contributing to improved food security and sustainable agricultural practices.","PeriodicalId":308,"journal":{"name":"Environment International","volume":"19 1","pages":""},"PeriodicalIF":11.8,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145209602","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}
