AI Article Synopsis
- The study examines PFAS concentrations in liver, fillet, and belly flap of beaked redfish and cod from the Svalbard region.
- Out of 17 substances tested, six PFAAs were found, with PFOS and PFUnA being the most prevalent in both fish species, particularly in the liver.
- Beaked redfish showed significantly higher PFAA levels than cod, raising concerns about potential risks for consumers due to exposure from eating these fish.
Article Abstract
The present study gives an overview about the concentration of PFAS in liver, fillet and belly flap of beaked redfish () and cod () caught in pristine arctic fishing grounds of Svalbard. Out of 17 analysed substances, only six perfluoroalkyl acids (PFAAs) could be detected in the fish. The most frequently quantified substances were PFOS and perfluoroundecanoic acid (PFUnA) in liver (100%) and fillet (at least 40% and 70%, respectively) of beaked redfish and cod, and in belly flap of beaked redfish (100%). Compared to cod, beaked redfish showed significant higher PFAA concentrations with highest levels in liver. Multiple comparisons of group differences for PFAA concentrations among fish species and matrices were independent of the evaluation method, but not for the PFAA-pattern analysis. The risk assessment of PFOS indicated that beaked redfish and cod caught in the Barents Sea can be a relevant exposure source for consumers.
