ABSTRACT

The aim of this study was to determine the extent of heavy metal accumulation in soils and potential risks of metals distribution in fruits, leaf and shoots in apple trees with rootstock M9 grown near smelter and mining areas of the Drenas, Kosovo.
Individual soil samples were collected from each plant to assess metal content in the immediate plant environment. Samples of soils, fruits, leaf and shoots have been analyzed for heavy metals (Pb, Cd, Ni, As, Zn, Cu, Cr and Fe) using atomic absorption spectrophotometry (AAS). The accumulation ratios of heavy metals were calculated to assess the potential health risks. The mean concentrations of the heavy metals in the soil were in order of magnitude Ni > Zn > Cu > Fe > Cr > Pb > Cd > As while that in the fruits of apple were in order of magnitude Ni > Cr > Fe > Pb > Zn > Cu > Cd > As; in the leaves were Ni > Cr > Fe > Zn > Cu > Pb > Cd > As; in shoots were Ni > Cr > Fe > Cu > Zn > Cd > Pb > As. Compared to control, contents of analyzed metals from plant tissues of apple trees in the contaminated area were significantly higher (p<0.001).
The high accumulation ratios for As (1.66), Cd (1.5) and Pb (0.81) were characteristic for the investigated species and indicate the accumulation ability from soils to plant.
