With the development of technology and industry, problem global air pollution has become difficult to ignore. We investigated association between pollutant concentrations daily all-cause mortality stratified analysis by sex, age, season. Data for six pollutants [fine particulate matter (PM 2.5 ), inhalable particles 10 nitric dioxide (NO 2 sulfur (SO ozone (O 3 carbon monoxide (CO)] rates were collected from 2015 2019 in Guangzhou, China. A time-series study using a quasi-Poisson generalized additive model was used examine relationships environmental mortality. Mortality data 296,939 individuals included analysis. The results showed that an increase μg/m PM , SO O NO CO corresponded 0.84% [95% confidence interval (CI): 0.47, 1.21%], 0.70% (0.44, 0.96%), 3.59% (1.77, 5.43%), 0.21% (0.05, 0.36%), 1.06% (0.70, 1.41%), 0.05% (0.02, 0.09%), respectively. effects more significant male than female individuals, cool season warm season, people 75 years or older those younger years. all associated with neoplasms circulatory respiratory diseases. two-pollutant models found may independently affect risk exposure excessive Guangzhou.
