Persistent exposure to nitrogen dioxide causes heart and lung disease.
The coronavirus cleared the air and the concentration of fine particles in Europe and the world has long been lower. This has been one of the few positive news stories in recent months since the world has been quarantined by the pandemic.
However, unless in an emergency, people in large cities breathe heavily polluted air, especially in the winter months. Surprising statistics show that COVID-19 mortality is highest precisely in regions where in the previous months there were high concentrations of nitrogen dioxide in combination with atmospheric inversion conditions that prevented the effective dispersion of air pollution.
The biggest outbreak of
infection in Bulgaria is
Sofia, where is the situation?
it is exactly like this
Nitrogen dioxide (NO2) is a pollutant and a greenhouse gas, which is a by-product of burning fossil fuels such as coal, gasoline, naphtha, fuel oil, etc. A study by the German Martin Luther University in Halle-Wittenberg demonstrates the link between long-term NO2 exposure and K-19 mortality. Using satellite images, scientist Jaron Ogen compares data on the distribution of nitrogen dioxide in the atmosphere with the number of victims. Deaths in 66 administrative regions in Italy, Spain, France and Germany were analyzed.
Results show that 3,487 of 4,443 died on March 19, or
as much as 78% were in five

in northern Italy
and central Spain
It is in the same five regions that the highest NO2 concentrations have been recorded in combination with very low air exchange. Scientists conclude that long-term exposure to this pollutant may be one of the most important contributing factors for the fatal outcome of COVID-19 disease in these regions, and possibly worldwide.
For the concentration of nitrogen dioxide in the troposphere (located between the Earth’s surface and 10 km high), the Sentinel-5 space satellite, operated by the European Commission under the Copernicus program, was used. Mapping the concentration of nitrogen dioxide in the troposphere over Europe reveals

Red is also the area of the Padaan Plain, which stretches from the slopes of the Western Alps to the coastal plains of the Adriatic Sea.
Of the five regions with the highest mortality rates, 4 are in northern Italy: Lombardy, Emilia-Romagna, Piedmont and Veneto. The fifth is the administrative area of the municipality of Madrid, which, like the Pada plain, is surrounded by mountain ranges.
The air in such regions remains more stable and the level of pollutants in the atmosphere is higher. In the valley and surrounded by mountains is the Bulgarian capital Sofia, which is the head of the general, national operational headquarters. Ventsislav Mutafchiiski named “the main outbreak with the most infected with COVID-19”.
Long-term exposure to NO2 is associated with hypertension, cardiovascular disease, higher hospitalization rates, chronic obstructive pulmonary disease, significant deficits in the development of lung function in children, lung damage in adults, and diabetes.
Other studies have also focused on the response of the NO2 immune system. They find that
nitrogen exposure

and causes an inflammatory response in the respiratory tract.
The same trend is seen in the United States, where of the nearly 795,000 infected over 250,000 are in New York State, known for its high levels of air pollution. About 19,000, or about 45%, of all the more than 42,500 deceased Americans are registered there.
A Harvard study also found that even a slight increase in airborne particle levels in the years before the pandemic was associated with a 15% increase in mortality. Scientists confirm that

Environmental poisoning, therefore, means poisoning one’s body, whose ability to protect against infection is severely restricted when he has been subjected to chronic respiratory distress.
German research concludes that chronic exposure to nitrogen dioxide can make a significant contribution to the high levels of K-19 mortality. Previous studies have shown that exposure to NO2 causes inflammation in the lungs, so according to Jaron Ogen, it is now necessary to demonstrate whether the presence of an initial inflammatory condition is related to the immune system response to the coronavirus.
