Organochlorine Pollutants in Chub, Leuciscus cephalus, from the Svratka River, Czech Republic

Abstract

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.
