Studies of Regularities of Accumulation and Dispersion of Chemical Elements in Soils of the South Aral Regions

When assessing the ecological state of agricultural landscapes in the Aral Sea region, the study of techno genic factors, which are superimposed on the entire complex of natural processes, is of decisive importance. The most dangerous type of techno genic impact on the natural environment is environmental pollution by chemical elements that are involved in biological, hydrogeochemical, biogeochemical and other processes. The relationship between these processes is not studied well. Moreover, the biogenic and sedimentation processes of purification and self-purification of ecosystems in interconnection with each other have not yet been studied sufficiently. Therefore, we carried out an ecological-geochemical study of waters, soils, bottom sediments of this region by the method of multielement instrumental neutron activation analysis.
