dc.description.abstractFish is one of the animal species used as an environmental bio-indicator. Fish were taken during the years 2002 – 2004 from the water reservoirs Smradavka and Korycany located in the South-east part of the Czech Republic. Seven fish species were monitored. Fish tissues were analyzed for both heavy metals and PCBs indicator congeners. Atomic absorption spectroscopy was used for heavy metals determination, high resolution gas chromatography was used for PCBs determination. The levels of particular trace elements ranged as follows (μg /kg fresh tissue): As 21.6–48.0, Cu 126–612, Ni 45–125, Pb 12.4–28.7 and Zn 3700–12500. Concentrations of cadmium were below the limit of determination (0.2 μg /kg) in all samples. The highest values (in μg /kg fresh tissue) were found for the PCB 153 congener in bream, eel and pike 12.5-22.5. The lowest concentration in all fish species was found for the PCB 52 congener 0.12-1.30. The sum of PCB indicator congeners ranged from 9.10 - roach to 53.9 - bream. All data are. The overall level of contamination in fish is low and the current limit for residues that is valid in the Czech Republic was not exceeded in any case.
