The change of the NO2, SO2, O3 and NH3+NH4 concentrations in air masses, passed from polluted southern regions to Lithuania was determined. The analysis based on chemical air pollutants data obtained at the Preila and Rūgšteliškės monitoring stations and back air masses trajectories analysis. Using filters and trajectories clustering the ozone concentration changes were estimated when the air masses crossed Lithuania from the east to the west. It was found that ozone concentrations have decreased by 16% on average.
