Repair and construction works are a source of dust pollution of the air environment of urban areas. The greatest damage to the quality of the air environment is caused by fine dust particles of fractions PM10 and PM2.5, the content of which in dust pollution generated during repair and finish-ing works can be very significant. In order to clarify the parameters of air pollution, concentrations were measured and the fractional composition of dust emissions of building materials often used in finishing works was determined. The proportions of dust particles of fractions PM10 and PM2.5 in dust emissions during finishing works were determined
