Abstract
Study of pollution of fine airborne dust in roadside areas
Incoming article date: 24.02.2020The article addresses issues related to the definition of particulate matter characteristics in the air of roadside areas. Fine suspended solid particles (TPM) of different size -10 and 2.5 μm are one of the main characteristics of atmospheric air quality. When monitoring the air environment on the maintenance of the firm weighed particles two indicators are used and normalized: PM2.5, PM10 are the firm weighed particles (English Particulate Matter, PM) with an aerodynamic diameter of 2.5 microns or less; Solid suspended particles with aerodynamic diameter of 10 microns or less. Dust particles from traffic are seen as an increasingly important source of air pollution, as the vehicle fleet is increasing worldwide, hence exhaust gas emissions, as well as particles from tire abrasion and road surface wear. Studies were carried out on the dust content of the roadside territories of the city of Volgograd. The article also pays attention to air quality indices, which will be used in monitoring the air environment of urban areas.
