- The article presents various forms of deterioration in sandstone panels of the Collegium Iuridicum building in Poznań. The facade of this building is exposed to various urban and rural pollutants, which have a very significant influence on the weathering of the stone. The climatic conditions in which the test building is located and structure of the stone are also an important factors of the weathering. They can significantly accelerate the stone destruction processes. Based on the ICOMOS guidelines, deterioration forms were described and classified in macro and micro scales. For this purpose, optical, cathodoluminescence and scanning microscopy with EDS analyser were used. As a result of the research, secondary mineralization and the presence of numerous elements in the black crusts were identified. They are directly related to polluted air and the combustion of solid fuels. The identified elements include: Na, Mg, Al, Ca, P, K, S, Hg, Pb, Fe, Ti, Sc, Ni, Br, Mo, Zn, Mn, gypsum, calcite, fly ash particle.
