Abstract

In frame of this paper are given the results and findings from the research performed for determination of metal pollution in the river Bregalnica. After the analysis and interpretation of data were confirmed the assumptions for increased values of the following metals: Zn, Pb, Cd, Cu, As and Ag. Since in the near vicinity is Sasa Mine for lead and zinc exploitation, especially interesting were the results for Pb that reached 0,019 mg/l, Zn that reached 0,029 mg/l, Cd that reached 0,005 mg/l, Ag that reached 0,056 mg/l, As that reached 0,110 mg/l in waters. Increased concentrations of metals quite often were of several times magnitude over the maximal allowed standards. The increase of metals concentration was highest in the area of the hydro accumulation Kaloimanci, and downwards through the flow of the river Bregalnica the concentration decreased.
