Abstract:
In order to examinate the presence of heavy metals in urban stormwater runoff, six main streets of Novi Sad city with high traffic intensity were chosen for the analysis. In recent years, after heavy rains these locations are also being flooded and the wastewater of the city of Novi Sad (combined sewage, industrial, municipal and stormwater) is directly discharged without any chemical or mechanical treatment into the Danube River. Samples of stormwater runoff were collected around the storm drains along the selected streets in april 2017. year after a rain event that lasted 2 hours. Stormwater samples were tested for zinc (Zn), copper (Cu) lead (Pb) and nickel (Ni). Concentrations of zinc were above limit of quantification (LOQ) (mean value 0.58 mg/L) for all six sampling locations in the city of Novi Sad, while for other metals, concentrations were under LOQ. The highest measured concentration of zinc was 1.21 mg/L. All detected values of zinc concentration were under the maximum allowable value for wastewater discharge to watercourse (2 mg/L).
