The aim was to evaluate the extent of pollution of the Svratka River with organochlorinated pollutants using the chub (Leuciscus cephalus) as a suitable bioindicator of the river contamination. The sum of 7 PCB congeners was found in range of 7.6-93.8 ng/g (with median of 31.7 ng/g) wet weight (ww), DDTs of 2.9-93.8 (29.9) ng/g ww, HCHs isomers of 0.1-5.3 (1.0) ng/g ww, HCB of 0.3-8.4 (2.2) ng/g ww and OCS of <0.1-0.5 (0.1) ng/g ww. Our results confirm predominance of metabolite DDE and higher-chlorinated PCB congeners and are comparable with similar studies and findings within the Czech Republic.
本研究旨在利用圆腹雅罗鱼（Leuciscus cephalus）作为河流污染的合适生物指示剂，评估斯夫拉特卡河（Svratka River）受有机氯污染物污染的程度。研究发现，7 种多氯联苯同系物的含量范围为 7.6-93.8ng/g（中位数为 31.7ng/g），湿重（ww）；滴滴涕（DDTs）的含量范围为 2.9-93.8ng/g（29.9ng/g）；六氯环己烷异构体的含量范围为 0.1-5.3ng/g（1.0ng/g）；六氯苯（HCB）的含量范围为 0.3-8.4ng/g（2.2ng/g）；硫丹的含量范围为<0.1-0.5ng/g（0.1ng/g）。研究结果证实了代谢物 DDE 和高氯代多氯联苯同系物的优势地位，与捷克共和国的类似研究和发现具有可比性。
