According to the Central Geophysical Observatory. Boris Sreznevsky assessment the state of atmospheric air pollution in the cities of Ukraine during the first half of 2019 was carried out according to observations in 39 cities at 129 stationary posts of the state monitoring system of the hydrometeorological service.
In general, for Ukraine in the first half of 2019, the average concentrations of harmful substances according to data from the cities where the observations were carried out exceeded the average daily maximum allowable concentration (GDCs) for formaldehyde - 2.3 times, for nitrogen dioxide - 1 , 5 times; the phenol content has reached the level of 1.0 GDCs.d.
Compared to the same period last year in 8 cities of Ukraine, the level of atmospheric air pollution increased - most of all in the Dnieper, Mariupol, Nikolaev, Krivoy Rog, Kherson, which is mainly due to significant average daily concentrations of formaldehyde, nitrogen dioxide, phenol, hydrogen fluoride, carbon monoxide, suspended solids (dust).
According to the Integrated Air Pollution Index (hereinafter - IPA), which takes into account the degree of atmospheric air pollution by five priority pollutants, a very high level of pollution in the first half of 2019 was observed in Dnipro and Mariupol, high - in Odessa, Nikolaev, Kamenskoye, Krivoy Horn, Kherson, Kiev, Lutsk, Zaporozhye, Rubizhne, Kramatrosku, Lisichansk.
