Sažetak
The effect of natural and technogenic factors on the Cu, Ni, Mn, Pb, Cd, and As compounds mobility and transformation were studied from an analysis of the fractional–group composition of Cu, Zn, and Pb compounds in the soils of areas adjacent to the Novocherkassk power station. Novocherkassk Power Station is one of the largest power plants at the South of the Russian Federation. The soils sampled from the non-arable sites at different distances from the Power Station. The investigated soils were meadowy chernozem, calcareous chernozem, and alluvial - meadowy soil. The total concentration of metals was determined by the X - ray - fluorescent meth od. Mobile forms of metals include exchangeable, complex and specifically adsorbed compounds were determined. The fractionation method by Tessier (1979) was applied for metal compounds determination. Changes in the composition of Cu, Zn, and Pb compounds i n the soils of technogenic landscapes were estimated. The effect of aerosol technogenic emissions on the mobility of metal compounds was revealed ; a higher metal mobility was found in soils with low buffering capacity. Common and specific features of the f ormation of Cu, Zn, and Pb compounds in soils were determined. The role of individual soil components in the retention of metals in clean and contaminated soils was established.
