Technogenic elements in especially protected ecosystems of West Ural taiga

Results of biogeochemical monitoring during 1994-2011, carried out within the program of nature chronicles in the territory of West Ural mountain and taiga reserves "Basegi" and "Vishersky" (Permskiy Krai) are presented. The main attention is given to accumulation of technogenic chemical elements in components of ecosystems. Dependence of technogenic pressure upon especially protected ecosystems on regional level of the economic activity, testifying to the leading role in technogenic loading of local polluters is established.
