The work analyses the emissions analysis for gypsum binder production. The major air pollutant is the suspended solids composed of a mixture of particles in air, which can be either solid or liquid and be a complex mixture of organic and inorganic substances. Studies have shown that excessive concentrations of inorganic dust (gypsum dust) generated by the open gypsum warehouse storage and thus the contribution of emission sources into total concentration of inorganic dust (dust plaster) average vary from 66,28% to 87,67%. The highest excessive concentrations of inorganic dust are registered at the border of regulated areas: up to 20% SiO2 (plaster dust) (from 5,9 to 16,0 shares of maximum allowable concentration (MAC)).
