The present study gives an overview about the concentration of PFAS in liver, fillet and belly flap of beaked redfish (Sebastes mentella) and cod (Gadus morhua) 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.

斯瓦尔巴特群岛北极垂钓场中的喙红鱼（Sebastes mentella）和鳕鱼（Gadus morhua）中的全氟烷基物质（PFAS）。

本研究概述了在斯瓦尔巴群岛原始北极垂钓场中捕获的喙红鱼（Sebastes mentella）和鳕鱼（Gadus morhua）的肝脏，鱼片和腹部皮瓣中PFAS的浓度。在17种分析物质中，鱼中仅检测到6种全氟烷基酸（PFAA）。喙红鱼和鳕鱼的肝脏（100％）和鱼片（分别至少为40％和70％），以及喙红鱼的腹部皮瓣（100％）中，最频繁定量的物质是全氟辛烷磺酸和全氟十一酸（PFUnA）。与鳕鱼相比，喙红鱼显示出较高的PFAA浓度，肝脏中含量最高。鱼种和基质中PFAA浓度的组差异的多重比较与评估方法无关，但对于PFAA模式分析则不然。
