The study mapped the estimated daily intake (EDI) of two C8-PFAS (PFOA and PFOS) from 212 marine fish species and found a global median EDI of 0.023 ng/kg/day.1[2] Higher EDIs occurred in North America, Oceania, and Europe, with significant contributions from consumed species such as codfish and herring due to high consumption rates.[1][2] PFOS exposure was more than one order of magnitude greater than PFOA exposure, which the authors attributed to the greater stability and bioaccumulation of PFOS in fish.1 The analysis showed that international fish trade shifts the risk of exposure from highly polluted areas to regions with lower residues, with European countries playing a central role in these trade flows.[1][3][4][5] Following the introduction of regulations in 2009, the hazard index for PFOS decreased by 72%, indicating the effectiveness of restrictions on this substance.2][5] The authors also note that measures to date have reduced exposures to legacy PFASs, but unregulated long-chain PFASs remain a source of increased risk, which calls for enhanced international cooperation and rules for fish trade.[1][2] The study provided exposure maps and models to assist policy makers in targeting regulations and monitoring to minimize human exposure through consumption of marine fish[1].
