Emerging Perfluorobutane Sulfonamido Derivatives as a New Trend of Surfactants Used in the Semiconductor Industry

Environmental Science & Technology, Год журнала: 2024, Номер 58(3), С. 1648 - 1658

The semiconductor industry has claimed that perfluorooctanesulfonate (PFOS), a persistent per- and polyfluoroalkyl substance (PFAS), been eliminated from production; however, information about the use of alternative compounds remains limited. This study aimed to develop nontarget approach discovering diverse PFAS substitutions used in manufacturing. A distinct fragment-based established identify hydrophobic hydrophilic features acidic neutral fluorosurfactants through fragments losses, including those outside homologous series. Ten sewage samples 5 plants were analyzed with target analysis. Among 20 identified spanning 12 subclasses, 15 reported for first time. dominant C4 sulfonamido derivatives, perfluorobutane ethanol (FBSE), sulfonamide (FBSA), diethanol (FBSEE diol), maximum concentrations 482 μg/L, 141 83.5 μg/L sewage, respectively. Subsequently, three ultrashort chain perfluoroalkyl acids (PFAAs) all samples, ranging 0.004 19.9 μg/L. Three effluent associated industrial wastewater treatment (WWTPs) further analyzed. finding, acetic acid series constitutes significant portion (65%-82%) effluents WWTP3 WWTP4, emphasizes conversion fluorinated alcohols during aerobic treatment. identification intermediate metabolites FBSEE diol, supported by our laboratory batch studies, prompts proposal novel metabolic pathway diol. total amount derivatives reached 1934 (90%), while PFAAs, which have typically received attention, was only 205 (10%). suggests are emerging as new trend industry, serving precursors contributing release their into environment.

A systematic review for non-targeted analysis of per- and polyfluoroalkyl substances (PFAS)

The Science of The Total Environment, Год журнала: 2025, Номер 960, С. 178240 - 178240

This review follows the PRISMA guidelines to provide a systematic of 115 peer reviewed articles that used non-targeted analysis (NTA) methods detect per- and polyfluoroalkylated substances (PFAS). literature highlights significant positive impact NTA in understanding PFAS environment. Within geographical bias exists, with most studies (∼60 %) conducted United States China. Future other regions (such as South America Africa) are needed gain more global understanding. More research is required marine environments atmosphere, current focus mainly on freshwater, groundwater, soil, sediments. The majority measuring environment, rather than commercial products (with exception AFFF). Non-lethal blood sampling has been successful for humans wildlife, but additional biomonitoring exposed cohorts understand health risks biotransformation pathways. mostly use liquid chromatography negative ionisation, which biases towards detection specific PFAS. Despite improvements data reporting quality assurance control (QA/QC) procedures, factors such false rates often overlooked, many workflows remain highly subjective. Perfluoroalkyl carboxylic acids (PFCAs) perfluoroalkyl sulfonic (PFSAs) detected classes, identified over 80 % studies, common routine monitoring. However, our >1000 from total 382 different 300 classes found fewer 5 studies. variety present limitations relying solely targeted methods. monitoring programs regulations would benefit considering comprehensive information
