Abstract

In this research, we analyzed the long-term variability and seasonal dynamics of NH₄⁺, Ca²+, NO₃^-, SO₄^2- ions prevailed in surface aerosol layer at the monitoring sites in the Baikal Region. During the warm period the chemical composition of the aerosol forms mainly due to the soil-erosion source; during the cold period power plants emissions are the most significant source. Quantitative estimates of the ion content in the aerosol at the monitoring sites, which indicate spatial heterogeneity of its chemical composition in the atmosphere of the Baikal Region, are given.
