The state of the atmospheric air pollution in the cities and towns of
Ukraine was assessed from the data of observations carried out in 54 cities at 166
stationary posts, and at two stations of transboundary transfer.
The atmospheric air contained 34 pollutants, including heavy metals. A large volume of
samples (about 60%) included the most spread substances: dust, sulphur dioxide, carbon
monoxide and nitrogen dioxide. Maximum permissible concentrations – diurnal average and
maximum single concentrations were introduced to assess the degree of the air pollution.
Annual average concentrations of pollutants were used in comparative analysis of the
Annual average concentrations of specific polluting substances in the cities where
observations were performed exceeded maximum permissible concentrations of formaldehyde
2.2 times, benzapyrene 1.8 times and phenol 1.3 times.
Annual average content of benzapyrene in
atmospheric air of cities in Ukraine in 1998, multiple to maximum permissible concentration
The content of ammonia and hydrogen fluoride was close to the maximum permissible
concentration. Average content of nitrogen dioxide was 1.3 times the maximum permissible
concentration, and dust content corresponded to the latter (Table 4.1.)
The highest pollution of atmospheric air was observed in Donetsk, Odesa,
Dniepropetrovsk, Gorlivka, Dzerzhinsk, Mariupol, Makyivka, Zaporizhia, Lutsk, Lugansk,
Cherkasy, Yenakievo, Dnieprodzerzhinsk and Slovyansk. The high level of pollution in these
cities was mostly caused by a high content of specific polluting substances and nitrogen
dioxide (Table 4.2.).
A certain decrease of pollution of atmospheric air in terms of content of impurities as
compared to 1997 was observed both in Ukraine as a whole and in separate cities.
