Abstract

The paper presents a study of the effects of soil bioremediation of contaminated soils by sowing Corn (Zea mays L.) and alfalfa (Medicago sativa L.) at three locations in the area of Zenica(Gradisce, Stranjani, and Ã… erici) in the spring of 2018. From March to September, soil samples were gathered to determine the concentration of the following heavy metalsiron (Fe), manganese (Mn), zinc (Zn), nickel (Ni), lead (Pb), vanadium (V), molybdenum (Mo), cadmium (Cd), chromium (Cr), copper (Cu) and cobalt (Co). The initial soil analysis shows that the soils average concentrations of manganese, nickel, vanadium, cadmium, and molybdenum exceed the permitted limit value. The values of average phytoaccumulation coefficients indicate that alfalfa removes heavy metals in the soil more successfully for iron (0.0346 mg/kg), nickel (0.0732 mg/kg), lead (0.0892 mg/kg), vanadium (0.1152 mg/kg), molybdenum (0.072 mg/kg) and chromium (0.2182 mg/kg). The highest averagetransfer coefficient valueswere achieved for zinc (3.4157 mg/kg) and copper (4.1129 mg/kg) when corn was used. Both plants reached the same levelof cobalt accumulation (2.5 mg/kg).
