CONTENT OF COPPER IN DESERT SOILS AND PLANTS OF EAST KAZAKHSTAN REGION

Abstract

One of the ecological characteristics of heavy metals is the knowledge of the normal (background) content in soils and the parameters of its possible anthropogenic pollution. Knowledge of the level of background content of heavy metals, including copper in soils is practical importance. The soil cover and vegetation of desert zones are diverse, but the elemental and chemical composition has been poorly studied and requires ecological and geochemical research, since the territory has an economic value. The article investigates the physico-chemical properties of the soils in the desert zone of East Kazakhstan region, as well as the content of the gross and concentration of the mobile form of copper (Cu). The copper content in the soils was determined by atomic absorption method. Statistical processing of the obtained data was carried out according to N.A. Plokhinsky using the Microsoft Excel program. To determine the content of gross copper and its exchange form in the soilforming rocks and soils of the East Kazakhstan desert zone, their ecological and geochemical assessment is given. The correlation dependence of copper on indicators of physical and chemical properties of soils is calculated. The data obtained reflect the patterns of copper distribution in the desert soils of East Kazakhstan region and can be used to develop a strategy for rational nature management, improving the organization of ecological and geochemical monitoring.
