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.

The article discusses the impact of emissions into the atmosphere, formed as a result of combustion of associated petroleum gas, on the chemical composition of settled dust near the gas torch. The paper presents full-scale studies of the emissions of a torch operating near a settlement, the chemical composition of particles in the obtained samples of settled dust is studied. In the course of the work, the results obtained were compared with research data obtained for areas where there is no flare combustion. As a result of this comparison, it was concluded that flare emissions have a significant impact on the chemical composition of settled dust in the vicinity of existing flare systems.
