Contamination assessment of Elbe river and its tributaries by means of biomarker detection and chemical analyses in chub (Leuciscus cephalus L.)
Original language description
In territory of the Czech Republic, the middle reach of the Elbe river and the lower reach of the Vltava river downstream Prague are the most polluted aquatic ecosystems. Heavy metals and organic coumpounds have been deposited here. They accumulate in the food chain and negatively affect the aquatic biota. The chub (Leuciscus cephalus L.) was selected as a suitable bioindicator for the field study. Blood plasma and tissue samples were collected from wild chub (Leuciscus cephalus L.) from 9 localities ofthe Elbe and Vltava rivers and from 1 locality of the Blanice river (control locality), Czech Republic, in 2003. Samples of blood plasma were analyzed for the yolk protein precursor vitellogenin (VTG), a biomarker for estrogen exposure, and for sex steroid - 11 - ketotestosterone (11-KT) to investigate for evidence of endocrine modulation. Liver samples were analyzed for EROD activity, biomarker of aquatic environment contamination by a large spectrum of industrial pollutants. Bile samp
