The 6:2 fluorotelomer sulfonamide (6:2 FTSAm)-based compounds signify a prominent group of per- and polyfluoroalkyl substances (PFAS) widely used in contemporary aqueous film-forming foam (AFFF) formulations. Despite their widespread presence, the biotransformation behavior these wastewater treatment plants remains uncertain. This study investigated FTSAm-based amine oxide FTNO), alkylbetaine FTAB), sulfonic acid FTSA) aerobic sludge over 100-day incubation period. alkylamine FTAA), primary intermediate product FTNO, was indirectly assessed. Their stability ranked based on estimated half-lives (t1/2): FTAB (no obvious products were detected) ≫ FTSA (t1/2 ≈28.8 days) > FTAA ≈11.5 FTNO ≈1.2 days). Seven transformation 15 identified through nontarget suspect screening using high-resolution mass spectrometry. pathways proposed. Interestingly, FTSAm hardly hydrolyzed to further biotransformed perfluoroalkyl carboxylic acids (PFCAs). Furthermore, novel for generation perfluoroheptanoic (PFHpA) from revealed.

More than 7000 synthetic compounds known as per- and poly-fluoroalkyl substances (PFAS) are applied to food packaging other materials provide fat, fire, and/or water resistance properties. These have exceptional environmental stability persistence due the strong C-F chemical bond, earning them moniker “forever chemicals”. Emission of PFAS from industrial waste leads water, air, soil contamination. Due this ubiquitous nature, combined with fact that in humans carcinogenic reprotoxic effects cause vaccine depression immunity system, may constitute a major threat human health. For reason, attention scientific community control bodies is increasing consequence legislation literature on constantly evolving. This review aims comprehensive overview state art about current addressing PFAS; targeted screening method for identification, detection quantification toxicity contamination matrices contact matrices. A latest research recent developments will insights into understanding its health implications. Moreover, it serve valuable reference further studies related could help informing future policy decisions.

The occurrence of sand and dust storms (SDSs) is essential for the geochemical cycling nutrients; however, it considered a meteorological hazard common to arid regions because adverse impacts that SDSs brings with them. One implication transport disposition aerosols coated anthropogenic contaminants. Studies have reported presence such contaminants in desert dust; similar findings related ubiquitous emerging contaminants, as per- poly-fluoroalkyl substances (PFAS), been relatively scarce literature. This article reviews identifies potential sources dust-associated PFAS can accumulate spread across SDS-prone regions. Furthermore, exposure routes their toxicity through bioaccumulation rodents mammals are discussed. major challenge when dealing quantification analysis from different environmental media, these include known unknown precursors need be quantified.

Given ongoing shift towards substitutes legacy rising role China as global leader production, background hotspot concentrations aquatic environment Western Countries (mostly E.U., U.S., Canada) are reported critically compared for first time, with special attention to short-chain perfluoroalkyl acids, novel like perfluoroether carboxylic sulphonic emerging 6:2 FTAB. Data on examined matrices show that i) total selected acids (PFAAs) generally higher China, except PFOS, ii) replacing their long-chain homologues but rarely monitored.
