Abstract
The problem of air pollution in the cities of Ukraine was described. The methodology of calculation of hydrocarbon emission on automobile overpasses and crossroads of Kyiv was suggested. By the number of bands, the number of cars was determined. The calculation has shown that at the same time near 300 cars can be on the overpass during peak hours. The average concentration of formaldehyde according to the calculations and observation data in 2016 was presented.
1. Introduction
Recently the problem of air pollution in the cities of Ukraine has become very sharp. [1,3,7,11 etc.] As main sources of formaldehyde which gets into the air the following groups are divided (which, in turn, are divided into primary and secondary): enterprises that use formaldehyde in their activities; sanitary burning of fuel and waste; movable sources; materials that contain formaldehyde (its evaporation occurs); city fires; land fields of domestic waste; natural sources. For the city of Kyiv, the formaldehyde formation from movable sources of hydrocarbon emission (secondary pollution) has a very powerful impact on atmospheric air pollution index. [4.11 and others]. It is the growth of number of vehicles that work on natural gas in big cities of Ukraine is connected with formaldehyde concentration increasing in recent years. The existing models and methods of calculation of formaldehyde concentration in big cities are connected, in particular, with the creation of mathematic models of air pollution basing on experimental data about pollution and on geoinformation system (GIS) data. The separate type of models concerns the realization of solving methods of spatial non-stationary, adequately diffusive kinetic equations for dissemination and turbulent dispersal of chemically reacting pollutants in the surface layer of atmosphere in urbanized areas. The nowadays existing methods of modelling both as the spatial dissemination of pollutants, analysis of regressive mapping dependencies and as the atmospheric diffusion models [7,8,9,14 and others] cannot be unified as there are a lot of differences of large cities which have been considered; so, many processes and atmospheric physic-chemical phenomena need to be included into the model.
