Measurements of the concentration of SO2, of aerosol concentration in air and of the composition and mass of water soluble cations and anions were performed during four seasons, spring, summer, autumn and winter, at two locations of the Railway Museum in Warsaw: Central Warsaw and Sochazew, which is located 50 km west of Warsaw. The time of wetness was calculated from precipitation data available from the Warsaw Targowek meteorological station. The measurements indicated a low to medium corrosivity for the atmospheres, which is typical for northern European inland environments with low chloride concentrations and relatively low SO2 concentration. The measurements indicated that sulphur dioxide SO2 was the main pollutant which gave increased corrosion at the sites, especially in Sochaczew, and that the presence of chloride, Cl-, and sulphate, SO42-, in the aerosol at significant levels contributed to the corrosion. Higher levels of Cl-, SO42- and H+ were measured in Sochaczew than in central Warsaw. The ISO 9223 corrosion category for SO2 and Cl- was 0 in central Warsaw and 1 in Sochaczew, indicating a significant contribution to the corrosion from anthropogenic sources in Sochaczew. The values for SO2 are slightly higher, but the PM10 values are lower, than tolerable levels for immovable (i.e. outdoor) cultural heritage given in a European wide assessment performed for CAFÉ (EU programme: Clean Air For Europe). The main factor that increases the corrosion to a higher ISO category (2-3) at the locations is the relatively humid climate. A further reduction of air pollutants should further reduce the corrosion, but the largest potential protection effect would be from measures to shelter the objects form rain and reduce the humidity in the air around the objects, e.g. by moving vulnerable smaller objects or particularly valuable objects to the indoor or applying other options for sheltering.
