Ecogeochemistry of technogenic landscapes: situational approach

Abstract

This article is dedicated to new approaches which have been appeared in the ecogeochemistry of technogenic landscape. All of them are concerning to different types of ecogeochemical assessment of whole landscape and considering a group of ecological facilities connected with a lack of chemical elements or their abundance. Special emphasis has been done to the assessment of ecogeochemical situations in technogenic landscapes, to the identification of different level of its favourability for vital functions of organisms. A number of gradations of ecogeochemical situations is a function of the acting factors quantity with the regard for their inner division. They determine conditions of migration and concentration of chemical elements, excess or lack of which is adversely affect a health and vital activity conditions of a man.
