The investigation of SO2, NO2,soot and benzo(a)pyrene (BP) has been performed at the background station on the eastern coast of the Baltic Sea since 1980. A significant decreasing trend has been observed for SO2 and NO2, while soot and BP concentrations were changing insignificantly. The decreasing SO2 and NO2 high concentrations ( >10μg·m-3) have been determined in the air masses coming from the Western and Central Europe to Lithuania since 1990. The concentration of SO2 in a range of 0-5μg·m-3 and the concentration of NO2 in a range of 0– 10μg·m-3 are characteric of the background atmospheric air.
