Laboratory analysis of the rainwater runoff from an urbanized area

Abstract

The aims of the research are to focus on the analysis of qualitative parameters of surface runoff from the urbanized area (parking, roadways); subsequently, to compare the measured concentration with the recommendations of Danish and Slovak standards. Rainwater sampling carried out at several sites in Serbia and Slovakia. In the analysis were monitoring, the qualitative parameters as pH value, water conductivity, chemical oxygen demand, and heavy metals. The results show the presence of copper, zinc, lead, aluminum, cadmium, chromium and nickel. The concentration of these parameters was several times higher than the allowed limit values. Based on these results, it is necessary to design measures to ensure surface runoff before infiltration.
