The aim of this work was to study the deterioration of various kinds of sandstone due to acid rain and SO 2 gas. The samples were taken from three quarries in Poland and one sample was from a tomb about 100 years old. To elucidate the mechanism of stone deterioration, simple experiments were performed. The sandstone samples were immersed for several weeks in SO 2 aqueous solution of pH ≈ 4. Similar experiments were performed using SO 2 aqueous solution of pH ≈ 1.5. The concentrations of Ca, Mg and Fe leached from the sandstone samples were measured with TXRF. An additional experiment was carried out with the use of radioactive 35 SO 2 . The samples were exposed to both 35 SO 2 aqueous solution and to 35 SO 2 gas. The autoradiograms obtained from the sample cross‐sections indicated that sulfur penetrated to the interior parts of sandstone samples, especially from SO 2 gas.
