【 摘 要 】

The authors carried out a dispersion analysis of the asbestos-cement dust sampled from the process equipment, the aspiration systems of the moulding shop, the general exhaust ventilation system and the air of the sanitary protection zone. A comparative analysis of the key parameters of process emissions of dust into the atmospheric air was performed through the standard method of calculation of hazardous substances emissions diffusion in the atmosphere, which is adopted in Russia, as well as through the method of calculation of hazardous substances emissions from non-organized sources. The deposition coefficient F for asbestos-cement dust was obtained through the two methods. The authors revealed that the standard method does not allow obtaining reliable results for dust with high polydispersity.
