mosekomonitoring analyzed the environmental situation in the city since the beginning of the input mode isolation. According to the results. This trend has continued after the may holidays.
the Positive dynamics is associated primarily with a significant reduction in the intensity of the traffic, as one of the main sources of emissions. Moreover, the decrease in the level of air pollution observed.
Since the beginning of the regime of isolation to the motorway network the concentration of substances in comparison with the usual level was lower in carbon oxide and a half times, nitrogen dioxide — half as much nitrogen oxide — 2.2 times, of suspended solids PM10 in the half. In residential areas the concentration of carbon monoxide decreased in 1.4 times, nitrogen dioxide — 1,8 times, sulfur dioxide — in 2.1 times, nitrogen oxide — by 2.2 times, suspended solids and PM10 — 1.6 times.
it is Recorded close to roads average for a month and a half concentration comparable with last year’s figures in residential areas, and the carbon monoxide and sulfur dioxide were lower 1.1–1.7 times.
Next to residential buildings the concentration of pollutants was below the level that was observed in these areas in 2019: carbon dioxide is 1.5 times, sulfur dioxide — 1.1 times, nitrogen dioxide — 1.7 times.
the Most recorded 22 April and 10 may. These days Moscow was under the influence of the cyclone that periodically rained and the wind blew with gusts of 10 meters per second. This suggests that the concentration of pollutants depends not only on emissions but also on weather conditions.
a number of indicators in the may holidays, the values of concentration of hazardous substances was minimal over the last few years. For example, close to roads maintenance in atmospheric air of dioxide and oxide of nitrogen and oxide of carbon over the last 10 years.
the Weakening of the regime’s self-imposed isolation resulted in a small increase in pollution. However, apparent indicators remain below typical for this time of the year.
When comparing the first week after the may holidays in 2020 and a similar period in 2019, the content of carbon monoxide and nitrogen dioxide in the air was below 1.1 and 1.2 times respectively.
In residential areas the air is cleaner compared to the previous year: the concentration of carbon dioxide below 1.5 times, nitrogen dioxide — 1.3 times, nitrogen oxide — by 2.2 times.
Analysis of the atmospheric air is conducted around the clock on the automatic stations around the city.
