Abstrakt: Currently, mining activities are mainly focused on economic efficiency and to a less extent on environmental safety. The natural environment experiences heavy impacts from mining activities. Various mining processes during the extraction of common mineral resources cause a significant increase in dust emissions. This article considers the dust fractions of granites, migmatites, marmorized limestone, ophicalcites, jades, and charoits. We determined the particle-size composition and morphology for all of the dust samples, calculated unit cell parameters and determined particle dimensions. As a result, we established that nanosize stone dust particles can enter living organisms, and their dimensions determine the impacts on the living organisms and environmental ecosystems, including the air. This research was conducted with financial support from RFBR within the scope of research project No 19-35-90096.
