The main objectives of this study were determination of concentration of five potentially toxic elements (Cr, Cu, Ni, Pb and Zn) and investigation of their distribution and environmental impact in soils, collected from urban parks in Belgrade, Smederevo and Pančevo. The optimized four-step BCR sequential extraction technique was used for element fractionation. Risk assessment code (RAC), individual contamination factors (ICF) and global contamination factors (GCF) were used to assess the environmental impacts of elements in soil samples. The study revealed that content of Cu and Ni at all localities, Pb in Belgrade and Smederevo and Zn in Smederevo exceed the limits established by local regulations, which may represent an environmental threat. Sequential extraction results showed that major portion of Cr existed in the residual fraction. The highest content of Cu and Ni from Belgrade and Pančevo was found in the first three fractions, while a large portion of Pb and Zn were found in reducible fraction, indicating that these elements may pose a great threat to environment in case of any change in environmental condition. According to the computed RAC, ICF and GCF the highest risk was found in Belgrade for Zn and Pb.
