Currently entering this field in operation will lead to significant changes in geological environment. State of geological survey for geological and economic estimate and commercial development of Bakchar iron site allow confirming that the natural and industrial system at an early stage of development is formed in the area. So, it is possible to explore it. The value of current information describing a kind of natural environment, especially in remote areas, increased. The need to perform a full evaluation of the current geo-ecological state of Bakchar iron-ore deposit environment, identification of major natural and man-made factors forming the ecological and geological environment of the study area and involved in commercial development of resources determine the relevance of the research. The main aim of the research is to evaluate ecological and geochemical state of Bachar area according to a comprehensive study of natural environments at the initial stage of development of natural and man-made system associated with the proposed exploration of Bakchar mine. Methods and types of research: neutron activation analysis, emission spectral semi-quantitative analysis, atmogeochemical (sampling of snow cover), lithogeochemical (sampling of soil), hydrogeochemical (sampling of surface and groundwater), gidrolitogeochemical (sampling of sediments), biogeochemical (study of biosubstrate - hair of children), radiogeochemical studies (measurement of exposure dose, as well as the content of U, Th and K). Results. Based on the geochemical studies the authors give the geochemical characteristics of natural environment (soil, dust aerosols, sediments, surface water and groundwater, biosubstrates) which will assess the environmental change in the area of the proposed development of the deposit and use this data to monitor the organization.
