In a long-term program polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) as well as dioxin-like polychlorinated biphenyls (DL-PCBs) were analyzed in the muscle tissue of eels (Anguilla anguilla), bream (Abramis brama), European chub (Leuciscus cephalus) and ide (Leuciscus idus) from the river Elbe and its tributaries Mulde and Saale. The variation of the PCDD/F and DL-PCB concentrations in all fish samples is very large, whereby the DL-PCBs predominate in comparison to the PCDD/Fs. In the eels, the concentrations (pg WHO-TEQ/g ww) for the PCDD/Fs lie in the range of 0.48-22 and for the DL-PCBs between 8.5 and 59. In the whitefish, the concentration range is 0.48-12 for the PCDD/Fs and 1.2-14 for the DL-PCBs. Statistical analysis using relative congener patterns for PCDD/Fs allow spatial correlations to be examined for sub-populations of eels and whitefish. The results are compared to the maximum levels laid down in the European Commission Regulation (EC) No. 466/2001 and the action levels of the European Commission Recommendation 2006/88/EC. Eels caught directly after the major flood in August 2002 as well as eels near Hamburg (years 1996 and 1998) show high concentration peaks. Compared to the eels whitefish is less contaminated with PCDD/Fs and DL-PCBs.
在一项长期项目中，对易北河及其支流穆尔德河和萨勒河中的鳗鱼（欧洲鳗鲡）、鲷鱼（欧鳊）、欧洲圆腹雅罗鱼和赤睛鱼的肌肉组织中的多氯二苯并对二噁英和多氯二苯并呋喃（PCDD/Fs）以及类二噁英多氯联苯（DL-PCBs）进行了分析。所有鱼类样本中PCDD/Fs和DL-PCBs浓度的变化非常大，其中DL-PCBs的含量相对于PCDD/Fs占主导地位。在鳗鱼中，PCDD/Fs的浓度（皮克WHO-TEQ/克湿重）在0.48至22的范围内，DL-PCBs的浓度在8.5至59之间。在白鱼中，PCDD/Fs的浓度范围是0.48至12，DL-PCBs的浓度范围是1.2至14。使用PCDD/Fs的相对同系物模式进行统计分析，可以检查鳗鱼和白鱼亚群的空间相关性。将结果与欧盟委员会第466/2001号法规规定的最高限量以及欧盟委员会第2006/88/EC号建议的行动水平进行比较。2002年8月大洪水后直接捕获的鳗鱼以及汉堡附近的鳗鱼（1996年和1998年）显示出高浓度峰值。与鳗鱼相比，白鱼受PCDD/Fs和DL-PCBs的污染程度较低。
