Particles were collected and segregated into 10 size fractions (0.025-10 μm) using two Berner type Low Pressure Impactors, sampled in parallel from the indoor and outdoor environment. Collected samples were analysed gravimetrically and by Ion Chromatography (IC). Typical mass size distributions were bimodal with minimum at about 1 μm, lower concentrations indoors and submicron range shifted to smaller particles. The results of IC revealed that ammonium sulphate and nitrate form about 30% of outdoor and about 20% of indoor mass of submicron fractions of PM, with indoor nitrate concentrations decreasing to zero. Most of the ammonium nitrate evaporated after penetration indoors probably due to higher indoor temperatures and fast surface deposition of gaseous nitric acid.
