“In 2020, the May holidays were held against the backdrop of a period of self-isolation, which is characterized mainly by reduced concentrations of pollutants,” the department said.

It is noted that the data of automatic stations located in residential quarters of the capital indicate that “the atmospheric content of carbon monoxide, nitrogen dioxide and sulfur dioxide decreased by 1.3 times, suspended particles of PM10 - by 1.5 times, nitric oxide - 2.0 times. ”
