    An abundance of ions and selected heavy metals in subsurface and near-bottom water samples as well as bottom sediments collected above and below of six hydroelectric power plants in the Słupia River basin was assessed together with their toxicity. Except some nutrients, ionic profile of river water indicates its high purity. None of toxicity was found for water samples using Microtox screening, Spirotox and Daphtoxkit F magna tests. Despite the fact that an average concentration of metals in water and bottom sediments was quite low there were some slight toxicity changes observed for sediments. Only in case of two hydroelectric power plants (Krzynia and Skarszów Dolny) sediments collected above were much toxic than these collected below. Observed changes are probably connected with natural or artificial origin of the supplying canals. However, generally hydroelectric power plants do not contribute to significant increase of heavy metals concentration as well as toxicity of both water and sediment samples. Nowadays, they play mainly as extraordinary touristic attraction enabling admiring beautiful architecture and principle of operation.
