Нейтралізація оксидів азоту на примагістральній території в умовах міста

Abstract. The article is devoted to the assessment of the ingredient pollution of atmospheric air with nitrogen oxides from the operation of internal combustion engines when traffic flows along the streets of the city of Kharkiv.Goal. The purpose of the study is to assess the emissions of nitrogen oxides on a section of a street in the city of Kharkiv, which is being investigated, and the development of measures to reduce ingredient pollution of the road area and close to the road, as well as in the interior of vehicles. This will ensure a decrease in the influence of unfavorable environmental factors on the body of drivers and passengers of cars and reduce the likelihood of road accidents. Methodology. To determine the concentration of nitrogen oxides in the surface layer of atmospheric air at different distances from the road, a model of the Gaussian distribution of impurities in the atmosphere was used. Results. According to the results of calculations, it was found that on the rise when traffic flows at a distance of 10 m from the carriageway, the concentration of nitrogen oxides exceeds the norm by 3.5 times. At such a concentration, there is a danger of harm to the health of people who are in vehicles or close to the road. Originality. To reduce the adverse environmental factors on the body of car drivers and the likelihood of road accidents, the placement of curbs is proposed. They are made with the addition of titanium dioxide, which will neutralize nitrogen oxides in the main area. For the individual protection of drivers and passengers of vehicles, it is proposed to widely use carbon filters in the ventilation system to neutralize pollutants in the passenger compartment of cars and buses.  Practical value. Environmental protection measures that have been developed will reduce the impact of unfavorable environmental factors on the health of the population.
