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.

Despite extensive poly/perfluoroalkyl substance (PFAS) discovery studies in various samples, the exposure spectrum fluorochemical occupational workers remains largely unexplored. Here, serum samples from 28 at a facility were analyzed using nontarget techniques, identifying 64 PFAS classes, including 15 novel ones such as pentafluorosulfur ether-substituted perfluoroalkyl sulfonic acids, hydrogen-substituted perfluoroalkylamines, and perfluoroalkylsulfonyl protocatechualdehyde esters. Temporal trend analyses (2008–2018) revealed stable levels for most but an increase perfluorobutanoic acid (PFBA) perfluorohexanesulfonic (PFHxS), suggesting industrial shifts long-chain to short-chain homologues China since early 2010s. Commonly reported structurally modified (e.g., hydrogen/carbonyl/chlorine substitution, ether insertion, unsaturation) likely historical byproducts of legacy production rather than intentionally manufactured alternatives. A Toxicological Priority Index-based risk assessment, integrating mobility, persistence, bioaccumulation indices, identified di(perfluoroakyl sulfonyl)imides, acids/carboxylic perfluoroalkylsulfonamidoacetic acids high-risk chemicals. Overall, exhibited higher mobility lower persistence PFAS, except chlorinated variants, which showed increased potential. This study highlights critical gaps historically emitted emphasizes need large-scale monitoring assessments manage emerging PFAS.
