Ecological and geochemical analysis of changes in nature of north of eurasia

Abstract

In the paper the geosystems and their components of the Arctic and Subarctic were investigated with the aim of detection of the main regularities of formation of the composition of the technogenic flows. It was also aimed at the analysis of the modern state of nature in the North of Eurasia. As a result the background levels and trends of changes of natural concentrations of toxicants were discovered as well as the main technologic pollutants. The average arctic values of concentration of metals were determined. The speed of recultivation of the broken soils was estimated. The primary regioning was carried out in order to perform various nature protective measures. The methods, developed in the paper, were introduced into operationAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
