TRAGOVI TEŠKIH METALA U VODAMA BELOCRKVANSKIH JEZERA

The paper analyzes the content of heavy metals, as well as the physical and chemical parameters of six Bela Crkva lakes. Obtained parameters were used for determination of the class of water quality. The results showed traces of As, Cr, Cu, Fe, Mn, Ni and Zn in all samples, while Cd, Co and Hg were not detected, and traces of Pb were detected in the samples of the waters of the Glavno and Malo Lakes. The values of other measured parameters were in the range that indicates that these lakes belong to I, II and III water classes. The aim of this paper is to point out the possible pollution of the lake by sports and recreational purposes, as well as agricultural activities around the lake.
