To assess the risk of excess mortality caused by exposure to PM_(2.5) in 5 cities in China. Surveillance data on daily concentration of PM_(2.5), meteorology and death-causes were collected from 2015 to 2018 in Harbin, Xi& apos; an, Nanjing, Chengdu and Guangzhou cities. Generalized additive model(GAM) was used to analyze acute exposure-response coefficients of PM_(2.5) exposure on the mortality. Using daily 24-hour average concentration of PM_(2.5) in 2018 to estimate the exposure levels of the population, with PM_(2.5) 24-hour average concentration limit of the ambient air quality standard(GB 3095-2012) for reference concentration(75 μg/m~3), and applicating the health risk assessment model, the excess deaths attribute to PM_(2.5) exposure in the 5 cities in 2018 was estimated. Attribute to PM_(2.5) exposure, the excess cases of death caused by circulatory system diseases in Harbin and Guangzhou were 35 and 92, the excess cases caused by respiratory diseases in Xi& apos; an was 70, the excess cases of caused by non-accident in Nanjing was 69, and the excess cases caused by non-accidental, respiratory and circulatory diseases in Chengdu were 588, 210 and 134 in 2018. PM_(2.5) exposure could increase the excess mortality risk, which varies among different cities.
