- Аннотация: The concentrations and distributions of Fe, Ti, Zr, Mn, Cu. Ni, Co, Cr, Pb, Zn associated with various particle size fractions have been analyzed in soils of two forested catenas located in the middle Protva river basin in Smolensko-Moskovskaya Upland. The results have shown that concentration of metals in a particular size fraction is defined by a complex of factors: element chemical properties, soil type, genesis of a soil horizon and a position in the catena. Clearly defined relationship between fraction size and metal concentrations exists for Ti and Zr. The highest levels of Ti were found in coarse and medium silt, while Zr showed its highest values only in coarse silt and in some cases in fine sand. Such metals as Fe, Mn, Co, Cu and Pb show high concentrations in sand, fine silt and clay fractions depending on a soil type and a genetic horizon. The maximum load of Cr, Zn and Ni (in the majority of cases) was found in clay fraction. The minimum load of Fe, Mn, Co, Cu and Ni were found in coarse silt fraction. HMs concentrations vary differently in each particle size fraction. It was found that fоr the majority of metals the variations are diminishing from coarser to finer fractions.
