Analysis of the chemical composition of dust particles in the warehouse of building materials

According to the World Health Organization (who), in addition to the already known (nitrogen oxide, sulfur dioxide, carbon monoxide), solid suspended dust particles were added to the most dangerous for human air pollutants. The inclusion of these particles in the list of especially dangerous pollutants has opened the way for a large number of studies, including their accounting in different conditions and for different types of economic activities in order to reduce their concentration in the air. To assess the harmful effects of dust on humans as air pollutants, it is necessary to know the chemical composition of these particles. The article considers the dust entering the atmosphere of warehouses for two variants (cases) of storage in soft tissues, in a cloth or plastic packaging. Dust of the most common building materials and dust of organogenic rocks, on the example of flask. The chemical composition and structure of materials on the basis of quantitative and qualitative microprobe analysis (EDS). Visually presented in the form of tables with the content of each element at different points of the same material and in the areas of two different materials.
