The most commonly used material in the monuments is the calcite crystals of CaCO3 which are thermodynamically stable mineral crystals. Weather conditions such as rain, snow, temperature, wind and atmospheric impurities negatively affect the appearance and structural strength of the marble. The dissolution in acid rain is one of the basic environmental degradation processes of marble artworks that remain outdoors. The main reason of marble abrasion is the solubility of calcite mineral in water. Due to the effects of acid rains, color change, loss of shape, contamination on the surface and dissolution occur on the structures forming the world cultural heritage. Fading and darkening of the structures is one of the most common effects of acid rain. In addition, surface swelling and structure breaks occur. The paling of the milky white marble of Taç Mahal in India, the blasts in the columns of the Capitol building in Washington DC, and some parts of the Acropolis in Athens, Greece, are examples of these effects. In this study, the effects of acid rain on marble monuments were investigated and the chemical reactions caused by atmospheric pollution on the surface of historical monuments were examined.
