Geoecological and geochemical assessment of the impact of NMMC mining enterprises on the environment

Abstract

Study of the dynamics of natural and man-made processes and their impact on the environment in the hills of Uzbekistan; study of ecological and geochemical processes occurring in technogenic and natural landscapes of mining enterprises of the NMMC; Conducting geochemical and analytical studies to identify the contents and distribution of toxic and other associated elements in technogenic waste from NMMC mining enterprises, soils, and plants in connection with their impact on the ecology of the environment. Study of geochemical features of the productive valuable and toxic element`s behavior in space and time in industrial waste area Geological and geochemical mapping of soil, plants and water sources. Study of the chemical composition, behavior and forms of occurrence of toxic elements (in soils, water streams, dust, gases, smoke) in the water area and in the vicinity of the Navoi Mining and Metallurgical Combine - geochemical ecology. As a result of investigations of initial samples by using mass spectrometric analysis, the limits of fluctuations and average contents of not only toxic elements, but also other associated elements were revealed.
