Abstract The blue crab is one of the most invasive alien species in Mediterranean Sea. Its remarkable surge availability suggests an imminent increase consumption. However, crabs are vulnerable to contamination by per- and polyfluoroalkyl substances (PFAS), known accumulate food chain pose health risks humans. Data on PFAS levels a few. This study investigates 26 113 UHPLC-HRMS. Results revealed higher concentrations cephalothorax than claws. PFHpA, PFHxS, PFOA, PFNA, PFOS, PFUnDA, PFDoDA, PFTrDA, PFHpS, PFBA were among detected PFAS. Total mean concentration ranged from 0.65 2.61 ng g−1 ww. Three exceeded maximum residue limits for PFHxS. Statistical analyses suggested correlation between contaminants presence size. PCA highlighted weight as potential predictor PFOS concentration. intake evaluation showed no risk consumers.

Most monitoring programs next to large per- and polyfluoroalkyl substances (PFAS) sources focus on drinking water contamination near source zones. However, less is understood about how these affect downgradient hydrological systems food webs. Here, we report paired PFAS measurements in water, sediment, aquatic biota along a gradient away from zones contaminated by the use of legacy aqueous film-forming foam (AFFF) manufactured using electrochemical fluorination. Clustering analysis indicates that composition characteristic AFFF detectable fishes >8 km source. Concentrations 38 targeted extractable organofluorine (EOF) decreased AFFF-contaminated concentrations remained above consumption limits at all locations within affected watershed. Perfluoroalkyl sulfonamide precursors accounted for approximately half fish tissues, which explain >90% EOF across sampling locations. Suspect screening analyses revealed presence polyfluoroketone pharmaceutical species, fluorinated agrochemical likely does not accumulate biological suggesting diffuse such as septic system inputs throughout watershed addition contamination. Based results, consider hydrologically connected regions watersheds would help ensure public health protection.
