Abstract Lithium-ion batteries (LiBs) are used globally as a key component of clean and sustainable energy infrastructure, emerging LiB technologies have incorporated class per- polyfluoroalkyl substances (PFAS) known bis-perfluoroalkyl sulfonimides (bis-FASIs). PFAS recognized internationally recalcitrant contaminants, subset which to be mobile toxic, but little is about environmental impacts bis-FASIs released during manufacture, use, disposal. Here we demonstrate that concentrations proximal manufacturers, ecotoxicity, treatability comparable such perfluorooctanoic acid now prohibited highly regulated worldwide, confirm the sector an unrecognized potentially growing source international release. Results underscore infrastructure merit scrutiny ensure reduced CO 2 emissions not achieved at expense increasing global releases persistent organic pollutants.

Oil refinery activity can be an emission source of perfluoroalkyl and polyfluoroalkyl substances (PFAS) to the environment, while contamination profiles in soils remain unknown. This study investigated 44 target PFAS soil samples collected from oil Southeastern China, identified novel PFAS, characterized their behaviors by assessing changes before after employing advanced oxidation using a combination nontarget analysis total oxidizable precursor (TOP) assay. Thirty-four were detected samples. Trifluoroacetic acid (TFA) hexafluoropropylene oxide dimer (HFPO-DA) dominant PFAS. Twenty-three 14 classes identified, including 8 precursors, 11 products, 4 stable TOP Particularly, three per-/polyfluorinated alcohols for first time, hexafluoroisopropanol (HFIP) quantified up 657 ng/g dw is TFA. Bistriflimide (NTf2) potentially associated with was also reported time highlighted advantage embedding assay reveal not only presence unknown but roles environmental processes. Overall, this approach provides efficient way uncover especially source-impacted areas.

Per- and polyfluoroalkyl substances (PFASs) are found everywhere, including food, cosmetics, pharmaceuticals. This review introduces PFASs comprehensively, discussing their nature identifying interconnection with microplastics impacts on public health the environment. The human cost of decades delay, cover-ups, mismanagement plastic waste is outlined briefly explained. Following that, long-term effects critically assessed. Risk assessment then reviewed, mentioning different tools models. Scientific research in United States America analyzed, taking into consideration Center for Disease Control (CDC)'s PFAS Medical Studies Guidelines. impact activities studies around world have focused levels food products dietary intake countries such as China, European countries, USA Australia. Moreover, drinking water regard to risks, mitigation, regulatory needs, account chemical contaminants safety. Finally, briefings specific regions discussed, referring Australia, Vietnam, Canada, Europe, (USA), South America, Africa. crisis a multifaceted issue, exacerbated by mismanagement, it discussed context applying following problem-solving analytical tools: Domino Effect Model accident causation, Swiss Cheese Theory Model, Ishikawa Fish Bone Root Cause Analysis. Last but not least, PFASs' Sustainable Development Goals (SDGs) 2030 rigorously discussed.

Per- and polyfluoroalkyl substances (PFAS) are synthetic long-lasting chemicals. Marine sediment is a major repository for PFAS in the environment; accordingly, this work investigated 45 legacy emerging samples of surface sediments cores (1940s-2020s) collected Pearl River outlets, its estuary, adjacent northern South China Sea (NSCS), one global pollution hotspots. The range total concentrations from river outlets NSCS was 244-14400 pg/g dry weight (dw) 31.6-363 dw, respectively. In cores, perfluorooctanesulfonate (PFOS) initially increased then declined around ten years ago. Levels long-chain perfluorinated carboxylates have been increasing since 1980s experienced an accelerated rise 2000s. Hydrogen-substituted ether sulfonate (H-PFESA) widely found first time. ratios 6:2 H-PFESA to chlorinated (Cl-) PFESA exceeded those exhibited trend with age, implying gradual transformation Cl-PFESA hydrogen-substituted analog sediments. A preliminary risk assessment indicated that ∑6:2 PFESAs PFOS posed medium high risks over recent decades.

Abstract The rapid increase of novel per- and polyfluoroalkyl substances (PFAS) raises concerns, while their identification remains challenging. Here, we develop a two-layer homolog network approach for PFAS nontarget screening using mass spectrometry. first layer constructs networks between homologs, with evaluation showing that it filters 94% false candidates. second builds classes to expedite the PFAS. We detected 94 in twelve waterproof products two related industrial sludges, including 36 not previously reported any sample. A local dataset is constructed retrospective analysis by re-analyzing our previous samples, revealing fifteen samples collected 2005. retrieval public database MassIVE uncovers from seven countries. reveal historic global presence PFAS, providing guidance management policy-making concerning persistent chemicals.

Amphibians are sensitive biomonitors of environmental pollutants but reports regarding per- and polyfluoroalkyl substances (PFAS), a class synthetic organofluorine substances, limited. In this study, samples water Chinese toads (Bufo gargarizans) were collected in Chaohu Lake, China. Tissue-specific bioaccumulation characteristics 39 PFAS, including 19 perfluoroalkyl acids (PFAAs), 8 emerging 12 PFAA precursors, investigated, the levels some biochemical indicators determined. The highest PFAS concentrations found liver [215.97 ng/g dry weight (dw)] toads, followed by gonads (135.42 dw) intestine (114.08 dw). A similar tissue distribution profile was between legacy occurrence two 2,3,3,3-tetrafluoro-2-propanoate (HFPO-DA) 6:2 hydrogen-substituted polyfluorooctane ether sulfonate (6:2 H-PFESA) amphibians for first time reported. Field-based factors HFPO-DA higher than perfluorooctanoic acid, indicating potential C8 compound. Males had significantly gonad females while estradiol increased with increasing certain (e.g., H-PFESA), implying that may trigger estrogenic effects especially male toads.
