[Health Benefit Evaluation for PM as Well as O Pollution Control in Chengdu, China from 2016 to 2020].

Both particulate matter with aerodynamics of less than 2.5 (PM) and ozone are the two main air pollutants in China, which seriously endanger human health. To estimate the adverse impacts of PM and ozone on human health during the implementation of air pollution prevention and control actions in Chengdu, both the generalized additive model and the nonlinear distribution lag model of epidemiology were adopted to explore the exposure-response relationship coefficients of daily ozone 8h maximum concentration average (O), as well as that of PM on disease deaths in Chengdu from 2014 to 2016.
