Halibut (Hippoglossus hippoglossus) and shrimps (Pandalus borealis) are regular foodstuffs for communities in northern Norway and important species for the coastal fishing industry. This is the first study to present a comprehensive overview of the contaminant status of these species, with emphasis on unregulated perfluoroalkylated substances (PFAS). The contaminant concentrations were low and within tolerable levels for human dietary exposure. Median Σpolychlorinated biphenyls (PCB) were 4.9 and 2.5ng/g ww for halibut and unpeeled shrimps, respectively. Concentrations of perfluorooctane sulfonate (PFOS) - the most abundant PFASs - were 0.9 and 2.7ng/g ww in halibut and shrimp, respectively. The halibut fillets were dominated by PCBs, which contributed to 50% of the total POPs load, followed by ΣDDTs; 26% and PFASs (18%), whereas shrimps were dominated by PFASs (74%). ΣPBDEs (polybrominated diphenyl ethers) contributed to 1-4% of the total POP load. Local sources are not contributing significantly to the contaminant burden in these species.
大比目鱼（庸鲽）和虾（北方长额虾）是挪威北部社区的常见食物，也是沿海渔业的重要物种。这是第一项全面概述这些物种污染物状况的研究，重点关注未受监管的全氟烷基化物质（PFAS）。污染物浓度较低，处于人类膳食暴露的可耐受水平之内。大比目鱼和带壳虾体内多氯联苯（PCB）的中位数分别为4.9和2.5纳克/克湿重。全氟辛烷磺酸（PFOS）是含量最高的PFAS，在大比目鱼和虾体内的浓度分别为0.9和2.7纳克/克湿重。大比目鱼片中以多氯联苯为主，占持久性有机污染物总负荷的50%，其次是滴滴涕总量（26%）和PFAS（18%），而虾中则以PFAS为主（74%）。多溴二苯醚（PBDE）占持久性有机污染物总负荷的1 - 4%。当地来源对这些物种的污染物负担贡献不大。
