Trace elements in Al-Fe-humus podzolic soils subjected to aerial pollutionfrom the apatite-nepheline production industry

Much data on the concentration and profile distribution of trace elements ( Rb, Cs, Ag, Au, Sr, Ba, Zn, Cd, Sc, La, Ce, Nd, Sm, Eu, Gd, Tb, Yb, Th, U, Zr, Hf, As, Sb, V, Ta, Se, Cr, Mo, W, Co, Ni, Br, and Ir) in Al-Fe-humus po dzolic soils subjected to intensive aerial pollution from apatite-nepheline mining and processing and the less significant pollution from the copper-n ickel enterprise are considered. The elements distribution in the profile o f polluted soils has a typical technogenic-accumulative pattern. The highes t concentrations are found in the upper organic horizons. Trace elements em itted in the course of apatite-nepheline production are fixed in the organi c soil horizon to alkalinization. Therefore, the distribution of these elem ents in mineral horizons displays a natural pattern, whereas their concentr ation is controlled by the lithogenic factor.
