| 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 of the 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 samples were anal

- Střední tok Labe a dolní tok Vltavy je možno považovat za nejvíce zatížené vodní ekosystémy cizorodými látkami na území České republiky. Významnými kontaminanty jsou toxické kovy a perzistentní organické sloučeniny. Kumulují se v potravním řetězci a negativně ovliňují vodní organismy. Jelec tloušť (Leuciscus cephalus L.) byl vybrán jako nejvhodnější bioindikátor pro studium účinků cizorodých látek přítomných ve vodě na rybí organismus. V roce 2003 byly na devíti lokalitách řek Labe a Vltavy na jedné (kontrolní) lokalitě řeky Blanice odebrány od volně žijících jelců tloušťů vzorky krevní plazmy a tkání. Vzorky krevní plazmy byly analyzovány na obsah vitellogeninu (VTG) a na obsah steroidního hormonu 11-ketotestosteronu (11-KT). Ve vzorcích jater byla zjišťována úroveň aktivity EROD. Vzorky žluči byly analyzovány na obsah 1-hydroxypyrenu (1-OHPY). Vzorky svaloviny ryb byly analyzovány na obsah toxických kovů (Hg, Cd, Pb, As), perzistentních organochlorovaných polutantů (PCB, DDT, HCH, HCB, OCS) a alky (cs)
