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.
