Air pollution: smog and fog in the large cities of Ukraine

The main factors of air pollution in large cities in Ukraine are described in the article and the main factors of smog have been analyzed on the example of Kyiv in the period January - February 2017. For the analysis of sample contamination points in Kyiv, we used a mathematical model of the spread of solid and gaseous pollutants with the main factors of influence on the scattering process of contaminants in the air: heat, turbulence, chemical kinetics, etc. As a result of the simulation, it was confirmed that the smog in Kyiv and surroundings was formed as a result of anticyclone and air pollution by harmful substances, soot and etc.
