Fluorine-related industrial discharges are the main source of per- and polyfluoroalkyl substances (PFAS) contamination in surrounding surface waters, but long-term environmental impacts their residual PFAS interactions between dissolved organic matter (DOM) field waters have rarely been discussed. In this study, concentrations 32 target were quantified, 50 identified semi-quantified by suspect nontarget screening, molecular characteristics DOM analyzed water Shanghai. Concentrations ∑PFAS 284 ∼ 3018 ng/L. Perfluorobutane sulfonate acid (PFBS) perfluorooctanoic (PFOA) remained predominant compounds at most sampling sites, hexafluoropropylene oxide trimer (HFPO-TA) exhibited extremely high values a few specific sites. Near historical fluorotelomer manufacturer which was closed 2017, concentration still high-level 1800 Thirteen including 7 iodinated perfluoroalkyl acids (IPFAAs) 100 % samples. A total 8134 formulas identified. For elemental composition, CHOS (24 %) has highest percentage, while for species, lignin (36 proportion molecules. When assignment fluorine included analysis, percentage fluorine-containing reached to 55 %, suggesting anthropogenic influences. Emerging PFAS, i.e., perfluoropentanoic (PFPeA) dimer (HFPO-DA) negatively related (p < 0.05) due microorganism activities. This study revealed persistent impact fluorine-related industries behavior aquatic environments, providing support systematic comprehensive evaluation health.
