Kachmar N. Migration and accumulation lead and cadmium in the ''soil-plant'' system in conditions of a Western Forest Steppe of Ukraine

In dissertational work results of researches on studying of features of migration and lead and cadmium accumulation on a profile dark gray podzolized soils and in barley plants in conditions of artificial pollution are stated. Negative action of ions of Pb2+ and Cd2+ at soil pollution at level 1, 5, 10 maximum concentration limits on indicators of a porosity and a specific surface of soil, a charge of a surface and cation-exchange ability of roots, quality indicators of grain of barley is revealed. It is shown that the basic part of lead and cadmium (66,5-86,7%) accumulates in roots. Cadmium is absorbed by barley plants in 2,5 - 3,6 times more intensively, than lead. For the purpose of reduction of receipt of ions Pb2+ and Cd2+ in plants of barley summer on polluted dark gray in the conditions of the western Forest-steppe of Ukraine it is necessary for soil to use a complex of agrotechnical actions and to support indicators of buffer properties of soil in optimum limits thanks to what transition contaminants from mobile in fixed inaccessible to form plants is provided.
