The issue of 12–year changes in the content of H+, Mg2+, Na+, Сl, K+, NO3, Ca2+, NH4+, and SO42– ions in soluble aerosol sampled in Mondy settlement, Southern Baikal, and on the Pacific coast is considered. In 2001-2006 and 2007–2012, despite a pronounced dispersion, the logarithms of geometric mean ion concentrations, without their seasonal differentiation, were in good agreement at Mondy station, Irkutsk, and Primorskaya station. The linear correlation coefficients were more than 0.96. The corresponding regression equations were derived. The issue of changing the ion order by concentration at different observation stations is studied. Tabular material on the content of ions, which can be used in modeling the chemical composition of ground aerosol particles in the South-Eastern Siberia is given.
