In this paper, an experimental assessment of dust emissions from warehouses of building materials from the point of view of their impact on the air environment is carried out. The technological operation of placement, in which dust is formed in a closed warehouse, is considered. It was revealed that in the process of placing building materials, the source of dust emission is aeration lights and windows. The dispersed composition of emissions entering the environment from unorganized sources (windows, aeration lamps) was experimentally determined by the height of the room.

This article is devoted to the study of the dust factor in the residential premises of a student dormitory during repair work, including the assessment of the regularities of the distribution of solid suspended particles by equivalent diameters (PM0.5, PM1, PM2.5, PM5 and PM10) and the determination of their concentrations.
