Orenburg Region soil and vegetation complex pollution risk evaluation

Abstract

Aim: The objective of the present study to find out the heavy metal accumulation in steppe landscapes soils and vegetation. Materials and Methods: On imitating modeling basis, the dependence of heavy metals in “soil-plant” system preferential distribution on their subsystems transition intensity was obtained. Result and Discussion: On the basis of experimental data system contamination risk analysis, a major percentage of soil trace elements accumulated in the plant root system with lowest pollution elements in aboveground parts. Conclusion: Based on the changes in soil-plant absorption capacity, different percentage of heavy metal migrates above and underground part of vegetation. The proposed method of analysis will help in the future environmental pollution risks evaluation studies
