Efremov I.V ASSESSMENT OF THE RISK OF CONTAMINATION OF SOIL AND PLANT SYSTEMS WITH HEAVY METALS UNDER ANTHROPOGENIC INFLUENCEOne of the tasks of ecology is to control heavy metal pollution of soils and plants in various industrial regions. By entering the food chain through cultivated plants, heavy metals pose a real threat to human health, given the ability of metals to accumulate in tissues and organs. An important task of environmental science is to study the migration properties of heavy metals in various soil and plant systems and to develop on this basis predictive models of heavy metals behavior in the natural environment.
In this paper, the author on the basis of analytical studies on the content of mobile forms of heavy metals in the components of various soil and plant systems, calculated the risks of soil and plant pollution by the previously proposed method. The integral and differential indices of migration properties of heavy metals are mathematically justified.
On the basis of the results, the proposed assumption about the selectivity of the migration properties of heavy metals in different soil-plant systems was confirmed. The obtained data about the risk of contamination of soils and plants with heavy metals allows to predict the phyto-remediation of contaminated land, allow us to determine the rate of negative impact on soil and plants hold ranking soil-plant systems on migration ability.Key words: Heavy metals, soil and plant systems, modeling, migration properties of heavy metals, pollution risk, integrated assessment of migration properties of heavy metals.
