Dust distribution from common minerals in the air of the Baikal Natural Territory

Abstract

In mountain quarries, the main factor influencing safety is dust aerosol of host rocks in the air. Therefore, it is necessary to ensure the environmental safety of mining quarries and improve health of the population. Due to a large number of factors influencing the distribution of dust, one of the main ways to obtain reliable information about this process is to study the distribution of dust. On the example of five mining facilities, an environmental risk assessment was conducted using statistical data on the control over activities of the enterprise. The index of atmospheric pollution was determined and the main parameters of the distribution of dust aerosols of granite, migmatite, marbled limestone, ophiocalcite, serpentinite, jade and charoite were identified. The area of distribution of dust aerosol for five quarries located on the Baikal natural territory was established. The consequences of dust pollution for ecosystems were described.
