The article shows the results of the dispersion analysis of natural dust in the steppe zone of the Volgograd region, obtained using a microscopic method. The integral functions and distribution of small particles in the selected samples after the application of the "dissection" method for particles up to 20 µm are presented.

This article is devoted to the study of the characteristics of fine dust particles in the gym. The monitoring of the dust content of the sports premises with fine particles was carried out, and the dispersed composition of the settled dust was also studied. The regularity of the dust distribution in the room depending on the measurement height is analyzed. The analysis of the state of the system of external respiratory organs is carried out.
