We analysed polychlorinated dibenzo-p-dioxins and furans (PCDD/F, dioxins), and polychlorinated biphenyls (PCB) in 13 fish meal, five fish oil, and seven fish feed samples. Polybrominated diphenyl ethers (PBDE), organotin compounds (OTC), and perfluoroalkylated substances (PFAS) were analysed in ten fish meal, two fish oil, and two fish feed samples. All measured TEQ concentrations of PCDD/F and PCB were below the maximum levels set by Directive 2002/32/EC. There was no correlation between concentrations of WHOPCDD/F-TEQ and indicator PCB in our samples. The most common congeners among PBDEs were BDE-47 and BDE-100. BDE-209 was present in five fish meals of the ten analysed. Tributyltin (TBT) was the predominant congener in all samples except in three fish meals, where monobutyltin (MBT) was the major congener. Perfluorooctane sulphonate (PFOS) was the predominant congener in six fish meals of the ten analysed. There was large variation in concentrations and congener distributions of the studied compounds between our samples. Our results underline a need to pay special attention to the origin and purity of feed raw material of marine origin.
我们分析了 13 份鱼粉、5 份鱼油和 7 份鱼饲料样品中的多氯二苯并对二恶英和呋喃（PCDD/F，二恶英）以及多氯联苯（PCB）。我们还分析了 10 份鱼粉、2 份鱼油和 2 份鱼饲料样品中的多溴二苯醚（PBDE）、有机锡化合物（OTC）和全氟烷基物质（PFAS）。我们样品中 PCDD/F 和 PCB 的所有测定 TEQ 浓度均低于指令 2002/32/EC 规定的最大限量。我们样品中 WHOPCDD/F-TEQ 与指示性 PCB 之间没有相关性。在我们分析的 PBDE 中，最常见的同系物是 BDE-47 和 BDE-100。在所分析的 10 份鱼粉中有 5 份存在 BDE-209。三丁基锡（TBT）是所有样品中的主要同系物，除了 3 份鱼粉，其中主要同系物是一丁基锡（MBT）。全氟辛烷磺酸（PFOS）是在所分析的 10 份鱼粉中的 6 份中的主要同系物。我们的样品中研究化合物的浓度和同系物分布存在很大差异。我们的研究结果强调，需要特别注意海洋原料饲料的来源和纯度。
