Abstract The PM2.5-related loss on life expectancy in 2013 in 74 key Chinese cities was evaluated based on the annual average PM2.5 concentration, exposure-response relationship coefficients of PM2.5, mortality due to 4 main diseases from “Global Burden of Disease 2010”, and the life table of urban permanent residents. Pollution caused by PM2.5 could attribute to a decrease in 1.48 years in life expecteny. Increases of 0.42, 1.04 and 1.26 years in life expectancy comparing with the 2013 level were estimated if the PM2.5 level was decreased to the second level of national air quality standard, the first level of national air quality standard and the Air Quality Guidelines formulated by World Health Organization, respectively. This study suggested that ambient PM2.5 pollution was an important determinant of the life expectancy of Chinese urban residents, and reducing PM2.5 could improve the life expectancy.
