Ecological Systems and Devices Annotation << Back Ecological and geochemical characteristics of soil overburden dumps Luchegorsky Coal Primorsky Krai Bubnova M.B. The article discusses the chemical and agrochemical properties of rocks dumps Luchegorsky coal mine compared with fertile soils. Noted that as a result posttechnogenic of soil-forming processes deteriorate physicochemical and alkali-acid soil parameters overburden dumps, it promotes differentiation of the mobility of trace elements contained in them. Given ecological and geochemical characteristic of the overburden, content of essential micronutrients, assessment of the level of their content and impact on the environment. It is established that the maintenance of microcells in the overburden does not go beyond maximum permissible concentration and regional clarks, but under certain physical and chemical conditions probably high maintenance of mobile forms of chemical elements that can have impact on formation of technogenic and geochemical situations and demands carrying out complex researches which will allow us to divide natural and technogenic anomalies and to define territories of an environmental risk. Keywords: overburden dumps; industrial pollution; ecological and geochemical characteristic; heavy metals; trace element content. Contacts: E-mail: 138_marina@mail.ru Pp. 47-55.
