78% of air is NO2. I don't see how a small increase can have an impact on corona virus fatalities.I just read this off of one of the sites I look to for updates. I thought this was pretty interesting. Kinda obvious that air pollution contributes to lung issues but non the less, the statistics are quite dramatic.
"Nitrogen dioxide (NO2) pollution [learn more] "may be one of the most important contributors to fatality caused by the COVID-19" a recent study [source] found after analyzing death cases from 66 administrative regions in Italy, Spain, France, and Germany. "Results show that out of the 4443 fatality cases, 3487 (78%) were in five regions located in north Italy and central Spain. Additionally, the same five regions show the highest NO2 concentrations combined with downwards airflow which prevent an efficient dispersion of air pollution. These results indicate that the long-term exposure to this pollutant may be one of the most important contributors to fatality caused by the COVID-19 virus in these regions and maybe across the whole world." [source]
It shall be noted that there are other potentially decisive factors, such as a higher population density or a higher rate of international travel, that are also typical characteristics of urban areas, in addition to higher levels of pollution."
- 83% of all fatalities (3701 cases) occurred in regions where the maximum NO2 concentration was above 100 μmol/m2
- 15.5% (691 cases) occurred in regions where the maximum NO2 concentration was between 50 and 100 μmol/m2
- 1.5% of all fatalities (51 cases) occurred in regions where the maximum NO2 concentration was below 50 μmol/m2
