One of the largest number of enterprises in Nizhny Tagil. Here he continued work, despite the pandemic, 42 industrial facility, and engaged in the field remained nearly 56 thousand people. Although harmful substances such as nitrogen dioxide, nitric oxide, oxide of cadmium, benzopyrene, hydrofloric and hydrogen sulfide, all also exceed the permissible limits, experts have recorded an improvement.
– there is a decrease in concentrations of nitrogen dioxide of about 38 percent, carbon monoxide about 9 percent, and a reduction in concentrations of sulphur dioxide, the Agency reports.
Experts suggest that a high level of contamination remains due to the operation of the plants, and a partial improvement of air quality turned out by reducing the number of vehicles during the quarantine.
among the study participants is also the largest city in the southern Urals – Magnitogorsk and Chelyabinsk. Here, as in other regions of the country, a high alert because of the coronavirus began to operate on March 18.
for example, in Magnitogorsk is just six industrial enterprises, which continued the work in the context of a pandemic and despite the fact that they employ nearly 28 thousand workers, the remote was only 11.5 percent.
the city is almost not changed the figures for carbon dioxide here, as before, they do not exceed the daily average limit of concentration. However, the content of certain substances turned out to be more than the permissible limits.
In Magnitogorsk during the period of increased readiness to increase the maximum allowable concentrations of suspended particles PM2.5, particulate matter PM10, nitrogen dioxide, benzopyrene, – stated in the results of the monitoring of Rosprirodnadzor.
Despite this, if you compare the emissions with the previous period, the situation has changed for the better. Examining the data for March and April, the researchers found that emissions of nitrogen dioxide have declined by 58 percent, carbon monoxide by 15%. Sulfur dioxide has been reduced by 73 percent.
This improvement is due to several factors: reduction of emissions from transport, objects of power and industrial giants.
But in the neighboring Chelyabinsk, the situation is different. In the period of the pandemic do not stop working with 10 large enterprises, mostly from the field of metallurgy. The results of the monitoring showed exceeding the permissible norms of etilbenzola, alkanes, and other pollutants.
the Data surveillance “from the air” showed that in comparison with March, in April significantly reduced the indicators remaining the same-read dioxide (59 percent) and 16 percent for carbon monoxide. But sulphur dioxide in the April air was more, with just 60 percent.
– This shows that the industrial ��enterprises, which are the main sources of air pollution in Chelyabinsk, made major and significant contribution to the level of air pollution, concluded the service.
overall, according to the study, the air in many Russian cities became cleaner thanks to lower transport stream. Also in each municipality for this was found and their individual causes. For example, in Bratsk the improvement of the ecological situation, the researchers associated with the completion of the heating period. Became clearer the air and in Lipetsk, but continues to have the lion’s share of influence on its quality have industrial giants. But in Mednogorsk, as in Norilsk, and in Cherepovets became easier to breathe, including by reducing emissions of local businesses.
