Abstract
Two common fish species, Perca fluviatilis and Alburnus alburnus, from Czarna Orawa River were examined for concentration of certain heavy metals (Zn, Cu, Cd, Pb) in their tissues. Significant differences between these two species were indicated. It was found that they have accumulated 20.679 ± 3.151 μg/g and 35.109 ± 9.001 μg/g of Zn, 0.3277 ± 0.1185 μg/g and 0.5444 ± 0.1851 μg/g of Cu, 0.6229 ± 0.0806 μg/g and 0.7508 ± 0.0820 μg/g of Cd, and 0.4039 ± 0.1730 μg/g and 0.3710 ± 0.1179 μg/ of Pb, respectively. Results obtained were discussed in the context of previously conducted studies. Increased efforts in order to improve water quality of the Czarna Orawa River system are expected. Also consecutive further studies on other water organisms seem needed.
