Abstract: Long-term investigations (2000-2015) of chemical composition of aerosol and its gaseous precursors were performed at three atmospheric monitoring sites in Southern Pribaikalye (Irkutsk, Listvyanka and Mondy) within the International EANET Program. For this period, concentrations of gases NH3 and SO2 increased in the atmosphere of Irkutsk and Listvyanka. In comparison with the earlier period of measurements (1993-1999), in 2011-2015 we recorded the decrease of concentrations of major ions (NH4+, SO42-, NO3- and Ca2+) in aerosol by 14-55% at site Irkutsk, by 56-77% at site Listvyanka and by 46-84% at site Mondy. Concentrations of Na+ and Cl- increased in two times at site Mondy. Changes of the quantitative composition of aerosol caused changes in ratio of ion concentrations in aerosol.
