Vol. 37, nr 3

55-62

The results of study of heavy metals content in water, suspended solids and bottom sediments of the Útrata River have been presented. The highest concentrations were observed for the dissolved form of Pb (0.35 mg/dm 3). All heavy metals under investigation were present in suspended solids (over 90%). Remarkable amount have also been found in sediments [mg/kg] Zn - 174, Cu - 76, Pb - 49, and Cd - 2.5. Water extracts showed lower concentrations, while EDTA extraction was several times more efficient (over 26%).
