Abstract

Data of 3-year-long observations of the chemical composition of precipitation, aerosol, soils and surface waters at three monitoring stations in the Baikal region are presented. The choice of observation objects is substantiated. Problems of natural objects" resistance to acidification are considered. The resistance of terrestrial ecosystems to acidification has been estimated quantitatively, and that of surface waters has been done so qualitatively. It has been demonstrated that symptoms of acidification are manifested most strongly in regions lee with respect to regional industrial centres at a distance of several tens and hundreds kilometres from them. The permissible acidity load for the soils of the territory under consideration varies from 1.25 to 1.4 keq/ (ha yr), while the maximal modern acidity load attains only 0.4 keq/ (ha yr).
