Abstract Introduction This paper reports polychlorinated dibenzo-p-dioxin (PCDD), polychlorinated dibenzofuran (PCDF), and polychlorinated biphenyl (PCB) concentrations in fish collected from Polish and Vietnamese farms and the related risk for consumers. Material and Methods Altogether, 160 samples were analysed using an isotope dilution technique with high-resolution gas chromatography coupled with high-resolution mass spectrometry (HRGC-HRMS). To characterise the potential health risk associated with PCDD/F and dioxin-like polychlorinated biphenyl (DL-PCB) intake, doses ingested in two 100 g portions of fish by adults and children were calculated and expressed as the percentage of the tolerable weekly intake (TWI) newly established by the EFSA in November 2018 at 2 pg WHO-TEQ kg−1 b.w. Results Generally, levels in fish muscles were low in relation to maximum limits (4), being in the range of 0.02–3.98 pg WHO-TEQ g−1 wet weight (w.w.) for PCDD/F/DL-PCBs and 0.05–24.94 ng g−1 w.w. for NDL-PCBs. The highest concentration was found in eel muscles. The least polluted were pangas and zanders and the levels were at the limits of quantification. Consumption of two portions of fish per week results in intakes of 9– 866% TWI by children and 4–286% TWI by adults. Conclusion Frequent consumption of some species (for example eel and bream) can pose a health risk to vulnerable consumers and especially children and pregnant women.

养殖鱼类作为波兰消费者的二恶英和多氯联苯来源

摘要 简介 本文报告了从波兰和越南养殖场采集的鱼类中多氯二苯并二恶英 (PCDD)、多氯二苯并呋喃 (PCDF) 和多氯联苯 (PCB) 的浓度以及对消费者的相关风险。材料和方法 总共使用同位素稀释技术和高分辨率气相色谱结合高分辨率质谱 (HRGC-HRMS) 分析了 160 个样品。为了描述与 PCDD/F 和类二恶英多氯联苯 (DL-PCB) 摄入相关的潜在健康风险，计算了成人和儿童在每份 100 克鱼中摄入的剂量，并表示为每周可耐受摄入量的百分比。 TWI）由 EFSA 于 2018 年 11 月新建立，2 pg WHO-TEQ kg-1 bw 结果一般来说，鱼肌肉中的含量低于最大限值 (4)，PCDD/F/DL-PCB 的湿重 (ww) 范围为 0.02-3.98 pg WHO-TEQ g-1 和 0.05-24.94 ng g- NDL-PCB 为 1 ww。在鳗鱼肌肉中发现最高浓度。污染最少的是pangas和zanders，水平处于量化极限。每周食用两份鱼会导致儿童摄入 9-866% TWI，成人摄入 4-286% TWI。结论 频繁食用某些物种（例如鳗鱼和鲷鱼）会对弱势消费者，尤其是儿童和孕妇构成健康风险。污染最少的是pangas和zanders，水平处于量化极限。每周食用两份鱼会导致儿童摄入 9-866% TWI，成人摄入 4-286% TWI。结论 频繁食用某些物种（例如鳗鱼和鲷鱼）会对弱势消费者，尤其是儿童和孕妇构成健康风险。污染最少的是pangas和zanders，水平处于量化极限。每周食用两份鱼会导致儿童摄入 9-866% TWI，成人摄入 4-286% TWI。结论 频繁食用某些物种（例如鳗鱼和鲷鱼）会对弱势消费者，尤其是儿童和孕妇构成健康风险。
