"Adverse weather conditions (such as the heat, strong wind over the surface) will last September 2-4, 2015, according to the Kyiv forecast meteorologist," as said in a statement.
According to the Central Geophysical Observatory, on Monday 31 August, the level of nitrogen dioxide pollution reached the five daily average MPC (maximum permissible concentration) and formaldehyde - 5-6 MPC. This contamination had been observed in numerous districts of Kyiv City (Bessarabska and Moskowska squares, Peremohy prospect, Obolon district; Dovzhenko, Popudrenko, Lazo, Kaunas streets; boulevard of Lesya Ukrainka).
Nitrogen dioxide and formaldehyde are highly toxic to people. When formaldehyde is released from a large area and enters the environment, such a release does not always lead to exposure. People may experience adverse effects such as watery eyes, burning sensations in the eyes, nose, and throat, coughing, wheezing, nausea, and skin irritation.
As was reported before, early September will be extremely hot, and there is a fire risk.
