The aim of the present study was to evaluate polycyclic aromatic hydrocarbon (PAH) contamination of the major rivers in the Czech Republic using 1-hydroxypyrene (1-OHP) content in chub bile as a biomarker. The highest concentration of 1-OHP was found in the Otava River at Topělec (80.5 ng mg protein(-1)); the lowest content of 1-OHP was found in the Vltava at Zelčín (9.6 ng mg protein(-1)). At all sites, bottom sediment samples were collected and analyzed for PAH content. The PAH content ranged between 1.2 and 15.2 mg kg dry mass(-1) at all sites. Statistically significant positive correlations (p < 0.05) between biliary 1-OHP and sediment PAH content were found. Correlation coefficients for total and individual priority PAHs ranged from 0.63 to 0.77.
