The work is devoted to the assessment of the negative impact of pollutant emissions on the air in the extraction and processing of sand and gravel. The maximum one-time and total emissions created by unorganized sources of one of the actually functioning enterprises are determined. The results of the calculation of the dispersion of the main pollutant (inorganic dust) are given. It is shown that the emissions of inorganic dust on the area of the enterprise exceed the values of the maximum permissible concentration and become lower than the MPC only outside the sanitary protection zone This demonstrates the need to comply with and control hygienic standards of ambient air quality near such enterprises.
