Title: Air Pollution Reduction and Mortality Benefit during the COVID-19 Outbreak in China Cord-id: mmvbkbjw Document date: 2020_3_27
ID: mmvbkbjw
Snippet: To control the novel coronavirus disease (COVID-19) outbreak, China undertook stringent traffic restrictions and self-quarantine measures. We herein examine the change in air pollution levels and the potentially avoided cause-specific mortality during this massive population quarantine episode. We found that, due to the quarantine, NO2 dropped by 22.8 {micro}g/m3 and 12.9 {micro}g/m3 in Wuhan and China, respectively. PM2.5 dropped by 1.4 {micro}g/m3 in Wuhan but decreased by 18.9 {micro}g/m3 acr
Document: To control the novel coronavirus disease (COVID-19) outbreak, China undertook stringent traffic restrictions and self-quarantine measures. We herein examine the change in air pollution levels and the potentially avoided cause-specific mortality during this massive population quarantine episode. We found that, due to the quarantine, NO2 dropped by 22.8 {micro}g/m3 and 12.9 {micro}g/m3 in Wuhan and China, respectively. PM2.5 dropped by 1.4 {micro}g/m3 in Wuhan but decreased by 18.9 {micro}g/m3 across 367 cities. Our findings show that interventions to contain the COVID-19 outbreak led to air quality improvements that brought health benefits which outnumbered the confirmed deaths due to COVID-19 in China
