Per- and polyfluoroalkyl substances (PFAS) are common contaminants of drinking water globally. Due to their large number diversity, extractable organofluorine (EOF) has been employed as a sum parameter measurement capture known unknown PFAS in environmental samples. However, current methods for determining EOF perform poorly trifluoroacetic acid (TFA) provide limited insights into the nature unidentified fluorine occurring To address this, we developed validated solid-phase extraction procedure determination with improved TFA recovery, which removes and/or accounts different species inorganic fluorine. The method produces two fractions: one containing mostly polar fluorinated (e.g., TFA, tetrafluoroborate, trifluoromethanesulfonate) another longer-chain PFAS. Hexafluorophosphate was distributed across both fractions. Application Stockholm revealed closed mass balance fraction I, predominantly (93%) consisting TFA.

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.

Per- and polyfluoroalkyl substances (PFASs) are a large group of anthropogenic fluorinated chemicals. Ultrashort-chain perfluoroalkyl acids (PFAAs) have recently gained attention due to their prevalence in the environment increasing environmental concerns. In this review, we established literature database from 1990 2024, encompassing biological concentrations (>3,500 concentration records) five historically overlooked ultrashort-chain PFAAs (perfluoroalkyl carboxylic sulfonic with less than 4 carbons): trifluoroacetic acid (TFA), perfluoropropanoic (PFPrA), trifluoromethanesulfonic (TFMS), perfluoroethanesulfonate (PFEtS), perfluoropropanesulfonate (PFPrS). Our data mining analysis reveal that (1) globally distributed various environments including water bodies, solid matrices, air, usually higher those longer-chain compounds; (2) TFA, most extensively studied PFAA, shows consistent upward trend surface water, rainwater, air over past three decades; (3) present organisms, plants, wildlife, human blood, serum, urine, sometimes similar compounds. The current state knowledge regarding sources fate TFA other is also reviewed. Amid global urgency regulate PFASs, particularly as countries worldwide intensified such efforts, critical review will inform scientific research regulatory policies.
