The correlations between sampling sites situated in the close vicinity of copper smelter (Bor, Serbia) based on heavy metal (Pb, Cu, Zn) content in plant parts and soil of acacia (Robinia pseudoacacia L.) were determined. Very strong correlations (R>0.9) were observed between the sites Town park and Hospital in the urban-industiral zone due to high air pollution in this sampling area. The perfo...
