Humans experience widespread exposure to anthropogenic per- and polyfluoroalkyl substances (PFAS) through various media, which can lead a wide range of negative health impacts. Tap water is an important source in communities with any degree contamination but routine or large-scale PFAS monitoring often depends on targeted analytical methods limited measuring specific PFAS. We analyzed 680 tap samples from the American Healthy Homes Survey II for using non-targeted analysis (NTA) expand detectable Based detection frequency relative abundance, about half identified were found only by NTA. (with varying degrees confidence) 75 distinct PFAS, including 57 exclusively detected The are members seven structural subclasses differentiated their head groups fluorination. Clustering categorized into four coabundance dominated subclasses. One group uniquely NTA contains zwitterionic other transformation products likely associated aqueous firefighting foam contaminants small number spatially correlated samples. These results help further characterize scope emerging experienced U.S. population via augment nationwide targeted-PFAS programs.

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.

Wastewater treatment plant (WWTP) discharges can be a source of organic contaminants, including pesticides, to rivers. An integrated model was developed for the Potomac River watershed (PRW) determine amount accumulated wastewater percentage streamflow (ACCWW) and calculate predicted environmental concentrations (PECs) 14 pesticides in non-tidal National Hydrography Dataset Plus Version 2.1 stream segments. Predicted were compared measured (MECs) from 32 sites that represented range ACCWW land use evaluate performance assess possible non-WWTP loading sources. Statistical agreement between PECs MECs strongest insecticides, followed by fungicides herbicides. Principal component analysis utilizing optical fluorescence ancillary water quality data identified urban runoff Pesticides indicated relatively larger sources WWTPs included dinotefuran, fipronil, carbendazim, thiabendazole, prometon whereas imidacloprid, azoxystrobin, propiconazole, tebuconazole, diuron more related runoff. In addition, generally comprised low proportion MECs, which indicates dominant beyond WWTP discharges. Cumulative potential toxicity higher with greater and/or located areas. Imidacloprid, carbendazim accounted largest portion across sites. The chronic aquatic life benchmarks freshwater invertebrates exceeded 82 % imidacloprid detections (n = 28) 47 fipronil 19). These results highlight ecological implications pesticide contamination also legacy effects soil groundwater Pesticide management strategies mitigate both current historical impacts may improve health ecosystems.
