This study investigates the immediate impact of the largest PFAS spill in the state's history on nearby aquatic ecosystems. Over 11 days, PFAS were sampled from nine surface waters, detecting 18 PFAS, predominantly perfluorooctanesulfonic acid (PFOS). A significant reduction in PFAS levels occurred within days due to clean-up efforts and natural attenuation (<em>e.g.</em>, dilution, adsorption, and aerosolization), in addition to downstream transport. Kruskal-Wallis and Steel-Dwass tests revealed significant spatial variability in PFAS, with PFOS, perfluorohexanesulfonic acid, and perfluoroalkyloctanoic acid remaining elevated near the spill but declined by 99.9 % at the Harpswell Cove estuary 3.2 km south of the spill. The rapid PFAS spread poses risks to the downstream environments. This study provides insights into post-spill PFAS dynamics and highlights the urgency of minimizing PFAS-based AFFF use and spills, and further research into long-term ecosystem and human health risks associated with PFAS contamination.</div></div><div><h3>Synopsis</h3><div>The aftermath of a major AFFF spill was analyzed to provide insights into immediate spatiotemporal distribution of PFAS.</div></div>","PeriodicalId":93463,"journal":{"name":"Journal of hazardous materials letters","volume":"6 ","pages":"Article 100150"},"PeriodicalIF":6.6,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143816821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Radish was selected as the model plant due to its global popularity as a widely consumed vegetable. DAN (1,5-diaminonaphthalene) was used as the MALDI matrix, and the mass spectrometry operating conditions were optimized to acquire the best PFAS signals. The results show that long-chain PFAS predominantly accumulated in the xylem of the edible storage root, where their high hydrophobicity limits upward translocation. In contrast, short-chain PFAS and PFOA exhibited stronger signals in the cortex and periderm, likely due to alternative transport pathways. This differential distribution highlights the significant influence of PFAS physicochemical properties, such as chain length and hydrophobicity, on their in-planta transport mechanisms. By precisely mapping PFAS within plant tissues, this study provides a powerful tool for identifying high-risk edible tissues and assessing human exposure risks through PFAS-contaminated crops. It also reinforces the urgent need for sustainable remediation strategies to reduce PFAS levels in agricultural systems, thereby safeguarding food safety, ecosystem health, and human well-being.</div></div>","PeriodicalId":93463,"journal":{"name":"Journal of hazardous materials letters","volume":"6 ","pages":"Article 100141"},"PeriodicalIF":6.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143169644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
