Abstract

Contamination of soils and plants (couch grass (Elytrigia repens)) were observed on monitoring sites, under the influence of the industrial enterprises of different profiles (steel (Mariupol, Alchevsk, Kamianske), chemicals (Shostka) and energy (Sumy)). The work is dedicated to determination regularities uptake of heavy metals from soil by plants technologically contaminated areas. The content of heavy metals in soils and plants were determined by atomic adsorption, and using ICP-MS analyzer ELENENT-2 (Germany).  Ecological-geochemical assessment of soil contamination on the total index made by the method Yu. Sayeta. To characterize the biogenic migration of heavy metals and biochemical features of plants used method I. Avessalomovoyi. Areas of research are characterized by medium (moderately dangerous) and high (dangerous) pollution. Geochemical association of heavy metals in soil were identified. Biogeochemical characteristics of plants of technogenesis zones were established. Evaluation absorption of heavy metals from soil by plants technologically contaminated areas was given. Heavy metals accumulated in the plants form a series: Mo > Cu > Sn > Mn > Co > Ni > Zn > Pb > Cr > V. Couch grass growing on soils of different types, with different levels of poly- and monoelement contamination characterized by selective accumulation of chemical elements. Coefficient of biogeochemical activity type that describes the intensity of the absorption elements by plants is 5-10. The higher this value, the more pollution characterized area. Ash content is 12.5 - 14.5%. Establishing relationships between the concentration of metals in the soil and in plants conducted by the example of the city of Mariupol. Ecological and geochemical studies showed that under strong anthropogenic impact barrier type accumulation characteristic of Cu, Zn and Pb. The absorption of these elements attributed to the accumulator type. Absorption of Mn, Cr and V plants classified as indicator type. The ability to use the results of biochemical studies plant cover to highlight areas of environmental risk and their rehabilitation was shown.Keywords: accumulation in plants, heavy metals, technogenesis zone.
