This paper presents the contents of Fe, Mn, Ni, Cr, Cu, Zn, Pb, Cd and Ca in the fresh and superficially altered granites of Polumir, Serbia (Yugoslavia), grus and soil, as well as in the leaves of hazel, hornbeam and Turkey oak grown at the same site. Although the fresh muscovite-biotite granites had the total contents of the mentioned elements, and the grus and soil (regosol) had only the fractions 2mm, their concentrations were compared in order to contribute to the knowledge of the behaviour of elements in the similar grus and soil over granites. The concentration of Ca in the leaves of hazel and hornbeam was significantly higher than in the leaves of Turkey oak. The concentrations of Fe in the leaves of the three tree species were higher than the averages of plants, while the concentrations of Mn, Zn, Cu, Pb and Cd were average (ECCE, 1994). The content of Ni in the leaves of hazel and hornbeam was average, while in Turkey oak it was below average values. By the applied method, Cr was not detected in the leaves.
