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.

Per- and polyfluoroalkyl substances (PFAS) are ubiquitous global contaminants where the ocean plays a critical role in PFAS cycling. Large estuarine systems conduits for anthropogenic contaminants, but little is known regarding small tidal creek systems. Surface waters from seven creeks were analyzed 16 target including legacy replacement PFAS. Mean total ranged 139.4 to 12,293.8 ng/L terrestrial influenced upland sampling sites 33.9-176.3 mouth sites. Nine negatively correlated with salinity positively DOC (p < 0.05), indicating that source of predominantly terrestrial. also had strong positive relationship percent impervious surface (R2 = 0.99), importance human land use influencing occurrence. Results this study will inform future investigations their dynamics at land-sea interface.

Perfluorooctanoic acid (PFOA) is a persistent environmental contaminant that resists biological degradation and accumulates in organisms. It disrupts zebrafish embryo development, affecting their heartbeat rate locomotion. Meanwhile, probiotics are known to enhance the development ossification of embryos. In this study, we examined toxic effects PFOA on growth bone formation potential probiotic Bacillus subtilis var. natto counteract its toxicity. Larvae were exposed 0, 50, or 100 mg/L from hatching 21 days post-fertilization (dpf), with without dietary supplementation (107 CFU/larva/day), they sampled at 7, 14, dpf. exposure reduced standard length dpf, while co-administration mitigated these effects. Craniofacial cartilage defects appeared larvae 50 7 14 impaired Probiotics counteracted abnormalities. also delayed ossification, correlating downregulation col10a1a, runx2b, cyp26b1, treatment restored normal ossification. These findings improve our understanding PFOA's detrimental demonstrating protective role against PFOA-induced developmental
