“…where C -total dust concentration in researched point, mg/m 3 , PM2,5 and PM10 -concentration of dust with the size less than 2,5 m and 10 m, accordingly, mg/m 3 , F (d)-integral distribution function of particles by equivalent diameter, %, d = equivalent particle diameter [9] For determination of dispersal composition and characteristics of dust in the air of storage facilities, the microscopy method was used [10][11][12]. In this regard, was conducted the dust analysis, sampled in the atmosphere from the storages for three types of the materials.…”
