Short-term Effect of Ambient Ozone on Daily Emergency Room Visits in Beijing, China

Abstract Little is known about the acute effects of ozone on morbidity risk in China. We conducted a time-series study to examine the association between ozone and daily emergency room visits (ERVs) in Beijing, China. We identified 7,088,309 ERVs between January 1, 2014 and December 31, 2015. A gene...
