The emissions concentration was reduced in all observed parameters.

According to analysts Mosekomonitoring during the regime of isolation from 30 March to 30 of April there is a reduced concentration of contaminants in the air. Positive dynamics is associated with a significant reduction in the number of cars in the capital. Private cars on the roads was two times less than a year ago. Since cars are a major source of emissions, namely the reduction of traffic impact on air quality in the capital.

“The results of the monitoring indicate that during isolation the concentration of pollutants below those usually seen levels. Figures for carbon monoxide fell by 1.6 times, nitrogen dioxide — by 1,9 times, nitrogen oxide — by 2.5 times, sulfur dioxide — 1.5 times, suspended solids and PM10 — 1.3 times. Reduction of pollution is typical for all types of urban areas. Positive dynamics were also noted at stations located in the Troitsky and Novomoskovsky administrative areas,” — said in

The Department of natural resources and environmental protection.

According to the Deputy Director of the Mosekomonitoring Elena Lepinoy, the peak hours that were previously given the sharp growth, are now without spikes. In the second half of the month, the air became cleaner, the minimum value marked on April 22. In General, over the past two weeks, the concentration of the main polluting substances in the atmosphere of Moscow was 1,1–1,2 times lower than in the early period of self-isolation. The largest decline is typical for the oxides of nitrogen.

“Improving air quality is a signal about how we can influence the state of the environment. A necessary measure may well be a public initiative, the practice of conscious consumption and responsible attitude to what surrounds us. This positive momentum could have been maintained after a period of isolation, the citizens will prefer public transport”, — said a member of the Public chamber of Moscow city, head of the laboratory of the “national research University “MPEI”” Evgeny Gasho.

In Moscow in the continuous mode has a modern automated system of monitoring of atmospheric air. It is based on a network of automatic monitoring stations of air pollution located in residential areas, near highways, on natural areas.

“The data is updated every 20 minutes, the system processes and structuring information that helps the experts to analyze the relevant information. Based on the collected indicators experts identify expected sources of pollution, observing the movement of air masses and predict their movement”, — said the Deputy Director of the HPBW “mosekomonitoring” Eugene Nikitich.

In addition, the system allows you to control the level of solar radiation and the influence of meteorological conditions on air condition.

“Moscow monitoring system is at the level of the best analogues in the world cities and meets all modern Russian and international requirements. It allows you to analyze data, to respond quickly to changes in environmental conditions and ensures the availability and transparency of environmental information,” — said the head of Department on branch projects of the information technology Department Alexander Antipov.

On the website of Mosekomonitoring everyone in real-time may obtain information on the results of measurement of pollutants at automatic stations.
