Abstract：Objective To explore the risk of acute excess death caused by atmospheric particulate matters (including PM10 and PM2.5) among people and the annual average number of excess deaths due to them in Wuhan City. Methods We collected the data regarding the number of daily death, the daily average concentration ofPM2.5 and PM10, and meteorological information in the urban area of Wuhan City from January 2014 to December 2018. Generalized additive model (GAM) was used to analyze the associations among PM2.5, PM10 and the number of non-accidental deaths, and the effects of PM2.5 and PM10 exposure on short-term excess death were characterized. Results During the 5-year period, the annual average concentration of PM2.5 and PM10 decreased from 88.7 μg/m3 and 115.4 μg/m3 in 2014 to 51.6 μg/m3 and 75.0 μg/m3 in 2018. The daily concentration ofPM2.5 and PM10 was significantly correlated with the number of non-accidental deaths, and there were significant lag-effects. At the lag of 0 day, the number of non-accidental deaths increased by 1.03% (95%CI:0.82%-1.23%) and 0.67% (95%CI:0.51%-0.82%) for every 10 μg/m3 increase in PM2.5 and PM10 concentration. During the 5-year period, the annual average excess death numbers of people daily exposed to PM2.5 and PM10 in the urban area of Wuhan City were 338 and 104, respectively. Conclusion The increased PM2.5 and PM10 concentration may lead to a significant increment in the number of non-accidental deaths, and significant increase the risk of short-term excess death in the residents.
