Abstract
The analysis of the actual air condition in the
city of Kyiv in the areas of big overpasses and
crossroads shows that the average annual concentration
of formaldehyde more than 3 times exceeds the
maximum permissible concentration (MPC) of this toxic
substance. One of the most powerful sources of
formaldehyde formation in the air of the city is motor
vehicles. The role of weather factors in formaldehyde
formation rate (K) depending on capacity of emissions
of internal combustion engines has been analyzed in this
article. The equation for determining rate constant has
been obtained, which depends on the temperature in the
city of Kyiv and on the value of effective energy
activation of the mentioned process. The comparison of
the calculated and measured values of the rate reaction
constant in Observation Point (OP) No. 9 in the area of
Leningradska square has been given. The conducted
research gives the opportunity to assess and obtain
forecasting data on atmospheric pollution and
probability of smog situations emergence in Kyiv. The
suggested methodology can be used for other cities in
Ukraine where motor vehicles are the main indicator of
photochemical smog emergence.
