COVID-19 lockdowns averted tens of thousands of premature deaths related to air pollution

Lockdowns initiated to curb the spread of the coronavirus in China and Europe at the beginning of the pandemic improved air quality, averting tens of thousands of deaths in regions where air pollution has a significant impact on mortality, a new study shows. According to research published in The Lancet Planetary Health, scientists at the University of Notre Dame found that particulate matter concentrations in China dropped by an unprecedented 29.7 percent, and by 17.1 percent in parts of Europe, during lockdowns that took place between Feb. 1 and March 31 in China and Feb. 21 to May 17 in Europe. Particulate matter (PM2.5)—tiny airborne particles smaller than 1/10,000 of an inch in diameter—comes from various combustion-related sources including industrial emissions, transportation, wildfires and chemical reactions of pollutants in the atmosphere.
