In 1995-1998 the contents of polychlorinated dibenzodioxins and dibenzofurans of 184 pooled fish samples were analysed. Sampling focused on fish and fishery products with a market share of more than 1% and covered all fishing grounds important for the supply of the German market. Investigation included 15 different fish species, shrimp, mussel and squid samples and various fishery products, typically on the German market. Generally lean fish species like cod, saithe or Alaska pollock were less contaminated on fresh weight basis than fat fish species like herring, Greenland halibut and sardine. In herring the dioxin content is related to the fishing ground. Low concentrations were found in North Sea herring, high concentrations measured in samples from the Baltic Sea. Dioxin contents in fishery products did not differ significantly from the raw fish samples. Results allow an estimation of the daily intake of dioxins and furans via fish consumption in Germany. Based on a daily fish consumption of 20 g the average intake of dioxins via fish is 6.2 pg WHO-PCDD/F-TEQs per person and day.
1995年至1998年期间，对184份鱼类样本合集的多氯二苯并二恶英和二苯并呋喃含量进行了分析。采样重点是市场份额超过1%的鱼类和渔业产品，涵盖了对德国市场供应至关重要的所有渔场。调查包括15种不同的鱼类、虾、贻贝和鱿鱼样本以及各种典型的德国市场上的渔业产品。一般来说，像鳕鱼、黑线鳕或阿拉斯加狭鳕鱼等瘦鱼类在鲜重基础上的污染程度低于像鲱鱼、格陵兰大比目鱼和沙丁鱼等脂肪鱼类。在鲱鱼中，二恶英含量与渔场有关。在北海鲱鱼中发现浓度较低，而在波罗的海样本中测得的浓度较高。渔业产品中的二恶英含量与生鱼样本没有显著差异。研究结果有助于估算德国人通过食用鱼类摄入二恶英和呋喃的每日摄入量。基于每人每天食用20克鱼的量，通过鱼类摄入二恶英的平均摄入量为每人每天6.2皮克WHO-PCDD/F-TEQ。
