T. Baraboshkina THE GEOLOGICAL FACTORS OF ECOLOGICAL RISK OF RUSSIA. (original) (raw)

The geological factors (natural or technogenically transformed lithosphere), which organisms react by adaptations is possible to consider as ecological-geological risk factors (ERF). They cause sickness of the people, oppression of ability to live phyto-, zoo- and microbocoenoses. Nowadays the majority of the investigators of the ERF allocate paramount importance to the study of negative effect of technogenic (geochemical, physical) factors. However, the biotic component of the ecosystem is affected a constant pressure of the natural geochemical and geophysical factors. Their synergetic influence appreciably causes a degree of comfort of existence of the biota, because the evolution of the lithosphere and biosphere goes in close relation. According to the systematics of the medical-ecological, biogeochemical, geo-logical, hydro-geological data, soils, rocks, fresh water of Russia and the other countries do not provide stable receipt in with a feed of all spectrum of vitally - impor-tant elements (I, F, Ca, etc.). As functional relations in “the lithosphere – biota" system the geological factors of ERF can be subdivided on a majority as: I - ecological - geochemical, II - ecological - geophysical and III - ecological – geodynamic by the time of influence (constant, temporary and short-term); the area of influence (local, regional and global); by a source of indignation (litho-, hydro-, atmogeochemical) and complex type by the form of ecological target (phyto-, zoo-, antropocentric and complex). The executed complex researches both natural, and transformed regions have allowed revealing the conducting local and regional ERF. Their knowledge allows at a regional level to adjust the quality of the imported foodstuffs (together with correction of a drinking water-supply) and to promote equalization of natural and technogenic effect of ERF.
