Exposure of heavy metals in Drenas site-Kosovo has risen dramatically in the last 30 years because of mining and smelting activities.This study investigated the heavy metal in soil, accumulation in different part of apples trees near the industrial sites of Drenas. The accumulation ratio values 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 > Fe > Cr > Cu > Pb > Cd > As while that in the fruits of apple were in order of magnitude Ni > Cr > Fe > Cu > Pb > Zn > Cd > As, in the leaves were Fe > Zn > Cu > Cr > Ni > Pb > Cd > As and in the shoots were Zn > Fe > Cu > Cr > Ni > Pb > Cd > 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 concentration of Ni, Pb, Cr, Fe etc. in the apple tissue increased with increase of heavy metals in soils from polluted area. The high accumulation ratio values for Pb (1.1), Cd (0.62), Cr (0.93) and Ni (0.46) were characteristic for the investigated specie and indicate an accumulation ability.
