The opoka-rock belongs to the silica-carbonate rocks commonly used in historical building. The research material in the form of rock fragments was taken from historical objects located in central Poland in Kazimierz Dolny on the Vistula river. In 8 time fractions according to NEN 7375: 2004 norm, the leachability of the main elements from the beryllium group considered as environmental indicators of building materials enriched with carbonate components was determined. After the application of the ICP sequential plasma-emission spectrometer according to the PN-EN ISO 11885 norm, the concentration of Ba, Mg, Sr, Zn, Mn was determined in the water eluates. In addition, physical and mechanical properties such as: open and total porosity, compressive strength in air-dry state, bulk density and specific density; were determined in accordance with the applicable standards. The results of the conducted research allowed finding that the number of leachabilities of the examined elements in decreasing succession were as follows: Mg > Sr > Zn > Ba > Mn. The highest leachability from the selected elements was found for Mg, which ranged from 0.22 to 1.14 ppm.
