N2 - This study used biochemical markers to assess contamination at two contaminated sites (Kraliky and Lichkov) and one control site (Cervena Voda) on the River Ticha Orlice, a left-side tributary of the River Elbe. The brown trout was selected as an indicato species. Enzymes of the first stage of xenobiotic conversion, namely cytochrome P450 (CYP 450) and ethoxyresorufin-O-deethylase (EROD) in the liver were selected as biochemical markers. Blood plasma vitellogenin concentrations were used to evaluate xenoestrogenic effects of contamination. Results were compared with the most important inductors of these markers, i.e. with organic pollutants. the highest contamination wit organic pollutants was at Kraliky, and this was reflected in increased cytochrome P450, EROD activity and vitellogenin concentrations. Significant differences were demonstrated in EROD activity and vitellogenin concentrations between Kraliky and Cervena Voda. At the most contaminated site (Kraliky), a significant negative correlation between EROD activity and vitellogenin concentration was demonstrated. This relationship was discussed from the point of view of a possible induction or inhibition of the assessed biomarkers at persistently highly contaminated sites.
