Perfluoroalkyl substances (PFASs) were investigated in five Baltic fish species (sprat, herring, salmon, trout, and cod). Each species' median lower bound (LB) concentration of ∑14 PFASs was as follows: in sprat it was 3.54 µg/kg wet weight (w.w.), in cod 2.15 µg/kg w.w., in salmon 2.10 µg/kg w.w., in trout 2.03 µg/kg w.w. and in herring 1.74 µg/kg w.w.. Regarding the species' median LB of ∑4 PFASs (perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), and perfluorohexane sulfonic acid (PFHxS)), sprat was the most contaminated with 2.90 µg/kg w.w. and herring was the least with 1.17 µg/kg w.w.. Among all PFASs, PFOS was found in the highest concentrations (range 0.04-9.16 µg/kg w.w.) and the percentage share in the total concentration of ∑14 PFASs was between 56 and 73%. The average proportion of linear PFOS (L-PFOS) in the total PFOS (branched and linear) was the highest in salmon at 89% and trout at 87%, and in the other three species it ranged from 75 to 80%. Different consumption scenarios were assumed and the intake of PFASs was calculated for children and adults. Dietary intake via fish consumption was 3.20-25.13 ng/kg of body weight (b.w.) for children and 1.68-8.30 ng/kg b.w. for adults. Baltic fish caught along Polish coastal areas are a significant source of PFASs, especially for children.
全氟烷基物质(PFASs)在五种波罗的海鱼类(鲱鱼、鲱鱼、三文鱼、鳟鱼和鳕鱼)中进行了研究。每种鱼类∑14PFASs 的中位数下限(LB)浓度如下:鲱鱼为 3.54μg/kg 湿重(w.w.),鳕鱼为 2.15μg/kg w.w.,三文鱼为 2.10μg/kg w.w.,鳟鱼为 2.03μg/kg w.w.,鲱鱼为 1.74μg/kg w.w.。关于物种∑4PFASs(全氟辛烷磺酸(PFOS)、全氟辛酸(PFOA)、全氟壬酸(PFNA)和全氟己烷磺酸(PFHxS))的中位数 LB,鲱鱼污染最严重,为 2.90μg/kg w.w.,而鲱鱼污染最少,为 1.17μg/kg w.w.。在所有 PFASs 中,PFOS 的浓度最高(范围为 0.04-9.16μg/kg w.w.),占∑14PFASs 总浓度的百分比在 56%至 73%之间。总 PFOS(支链和线性)中线性 PFOS(L-PFOS)的平均比例在三文鱼中最高,为 89%,在鳟鱼中最高,为 87%,而在其他三种鱼类中,其比例范围为 75%至 80%。假设了不同的消费情景,并计算了儿童和成人对 PFASs 的摄入量。通过鱼类消费摄入的 PFASs 量为儿童 3.20-25.13ng/kg 体重(b.w.),成人 1.68-8.30ng/kg b.w.。在波兰沿海地区捕获的波罗的海鱼类是 PFASs 的重要来源,尤其是对儿童而言。
