摘要：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.
