Concentrations of the sum of the seven indicator PCBs (Sigma7 iPCBs) measured in non-commercial European eel (Anguilla anguilla L.) in Flanders are high: in 80% of all sampled localities, the Belgian PCB standard for fish was exceeded. The objective of this study was to assess the intake of the Sigma7 iPCBs through consumption of eel by recreational fishermen and to compare it to the intake of a background population. The median estimated intake for recreational fishermen varied between 18.4 and 237.6 ng iPCBs kg(-1) bw day(-1), depending on the consumption scenario, while the estimated intake of the background population (consumers only) was 4.3 ng iPCBs kg(-1) bw day(-1). Since the levels of intake via eel for two intake scenarios were, respectively, 50 and 25 times higher than the intake of the background population, the body burden (BB) might be proportionally higher and reach levels of toxicological relevance. The intake of the seven iPCBs via consumption of self-caught eel in Flanders is at a level to cause serious concern. The Flemish catch-and-release obligation for eel, established in 2002, should be maintained and supervised (more) carefully.
在法兰德斯地区，对非商业性欧洲鳗鱼（欧洲鳗鲡）体内七种指示性多氯联苯（Sigma7 iPCBs）的总和进行测量，结果显示其浓度很高：在所有采样地点中，80%的地方都超过了比利时鱼类的多氯联苯标准。本研究的目的是评估休闲渔民通过食用鳗鱼摄入Sigma7 iPCBs的情况，并将其与背景人群的摄入量进行比较。根据消费情景的不同，休闲渔民的估计摄入量中位数在18.4至237.6纳克iPCBs/千克体重/天之间，而背景人群（仅消费者）的估计摄入量为4.3纳克iPCBs/千克体重/天。由于两种摄入情景下通过鳗鱼的摄入量分别比背景人群的摄入量高50倍和25倍，因此身体负担（BB）可能会相应更高，并达到毒理学相关水平。在法兰德斯地区，通过食用自己捕获的鳗鱼摄入七种iPCBs的水平令人严重担忧。2002年制定并实施的法兰德斯地区鳗鱼捕获后放生的规定应继续维持并（更加）严格监督。
