Abstract

Monitoring data on the ion composition of precipitation and the water-soluble fraction of aerosol have been used to identify two types of aerosol particles in the surface atmosphere of Irkutsk (“metal” and “ammonia” groups). The aerosol acidity is basically governed by the acidity of ammonia particles, and the ion composition depends on air relative humidity (RH). Preliminary estimates are given for the distribution of major cations and anions by aerosol groups.
