The aim of this study was to analyze the dust load in St. Petersburg based on the measurements of dust levels in different areas of the city using a CEM DT-9880 portable dust particle counter. A uniform one-character bottom up zoning was performed to determine the parameters, and the dependencies of dust distribution on various factors were identified using the “Ecolog” software package. The zoning was based on more than 2.5 thousand measurements of dust levels. An effective and rational solution to the problem of increased aerotechnogenic load in different areas of the city through the use of modern technologies of hydro-dedusting of city roads with a dust-binding solution based on surfactants was proposed for increasing the adhesion ability of the solution to the standard roadbed.
