Total concentrations of chemical elements do not exceed Clarkes values. The distribution of elements in the soil profile reveals the existence of geochemical barriers in the upper (A soil horizon) and middle (B soil horizon) part of the soil profile. The levels of Zn, Pb, Cu for majority of plants was near Clarkes, Fe, Mn, Co lower, and Cd ranged from average values to values several times higher than Clarkes. The concentration factor (F) (metal content in plant ash/metal content in parent material of the soil] for Fe, Mn is several times higher than the average for terrestrial vegetation [average metal content in terrestrial vegetation ash/metal content in lithosphere]; CF values for Cu and Cd exceed the Clarkes values by 10 times or more; CF for Pb, Zn, Co is comparable to average values.
