Opis:
Sandstones are a commonly used stone in the architecture of Poznań. They are constantly affected by deterioration processes. This is mainly linked to pollution, which is a consequence of the city development. This is manifested, among others, by the emission of harmful substances from traffic routes, as well as the combustion of solid fuels in the city centre. The research is focused on the sandstone elevation of one of the monuments of the Royal-Imperial Route in Poznań - the current building of the University of Economics and Business in Poznań dated to the beginning of the 20th century. The research was carried out both -on a macro- and microscale. Taking into account the ICOMOS glossary (International Council on Monuments and Sites), the types of damage on the façade on a macroscale were classified. The most common problem was the black crust on the surface of stone panels. Thanks to the use of optical, scanning and cathodoluminescence microscopy, it was also possible to analyse various types of contaminants on a microscale that appear in the building elevation. As a result of the research, dust particles, metals such as lead, tin, zinc, iron, and sulphur and nitrogen compounds that were part of dust particles were found. Deterioration of the façade caused by soiling derived from traffic-related particulate matter, deposition of nitrates from exhaust and other emission sources may seriously impact natural building stones.

Opis:
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.

Opis:
Stone has been used in architecture since Antiquity. The processes of its deterioration in different buildings have always been associated with natural processes of its weathering (physical, chemical, biological). However, this situation has changed over centuries. Currently, air pollution (mainly in urbanised areas) has a significant impact on the accelerated weathering of stone monuments. The research presented in this paper concerns the deterioration of stone facade of the 19th century building of the National Archive in Poznań, where the latest factor (contemporary air pollution) plays the greatest role. Based on the ICOMOS glossary, selected forms of deterioration were described and classified in macro and micro scales. For this purpose, optical and scanning microscopy and X-ray diffraction were used. As a result of the research, lichen species composition and secondary mineralisation in the black crust were identified. Elements, such as: barium, zinc, lead, and iron, which were detected on the black crust, were directly related to anthropogenic pollution caused mainly by combustion and low emissions.
