  • Study of pollution of fine airborne dust in roadside areas

    The 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.

  • Research of PM10 and PM2.5 fine dust pollution in the air of the city of Volgograd

    An important problem of modern ecology is air pollution for most cities. Studies show that the largest danger to the human body is particles up to 10 microns in size, therefore, the content of suspended solids PM10 and PM2.5 (concentration) is controlled. The article presents the results of studies of air pollution with fine dust in the winter season
