In this study, the results of a comprehensive assessment of the variability in the occurrence of ten perfluorinated compounds (PFAS) in fish tissues originating from 2014 to 2019 from six fisheries in the Baltic Sea are presented. A total of 360 fish samples of three species (perch, herring and flatfish) were analysed. For the determination of PFAS, both linear and branched stereoisomers, LC-ESI-MS/MS technique preceded by simultaneous SPE isolation was validated and applied. The total concentration of all determined PFAS compounds shows that the highest levels were observed in the Szczecin Lagoon (4.8 ± 0.7 µg/kg) and the lowest in the Pomeranian Bay (1.9 ± 0.1 µg/kg). In most samples, the dominant compound was perfluorooctane sulfonic acid (PFOS). The present research enabled the assessment of the variability in the occurrence of PFAS stereoisomers in marine fish.
本研究展示了对2014年至2019年来自波罗的海六个渔场的鱼类组织中十种全氟化合物（PFAS）出现情况的综合评估结果。共分析了三种鱼类（鲈鱼、鲱鱼和比目鱼）的360个鱼样本。为测定PFAS，包括线性和支链立体异构体，采用了先进行固相萃取（SPE）分离的液相色谱 - 电喷雾串联质谱（LC - ESI - MS/MS）技术并进行了验证。所有测定的PFAS化合物的总浓度表明，什切青泻湖（4.8±0.7微克/千克）中的含量最高，而波美拉尼亚湾（1.9±0.1微克/千克）中的含量最低。在大多数样本中，主要化合物是全氟辛烷磺酸（PFOS）。本研究使得能够评估海洋鱼类中PFAS立体异构体出现情况的变异性。
