    This thesis concerns the degree of pollution of Cd, Zn and Pb deposits of the Matylda River channel (Chrzanow region). Therefore, collected 19 samples of bottom sediments from about 9 km river section, wherein examined the pH and Eh and determined the contents of Cd, Zn and Pb by ICP-MS method. Collected also 9 samples of water,wherein specified pH, electrolytic conductivity, examined the content of major anions and cations, and selected heavy metals determined. The obtained values of heavy metals in sediments reached the highest concentrations of Cd - 458 mg/kg, Pb - 58,456 mg/kg and Zn - 86,814 mg/kg. These quantities highly exceed both the background adopted for the local Polish rivers and the local geochemical background. It was found that very high concentrations of elements must be the result of multi-channel discharge into the Matylda River, mine water from the lead and zinc mine Matylda.
