Short-Term Interaction Effects of PM_2.5 and O₃ on Daily Mortality: A Time-Series Study of Multiple Cities in China.

ABSTRACT: In recent years, PM_2.5 and O₃ have been the two main pollutants affecting public health in China, but the interaction of the two pollutants on human health remains unclear. A two-stage analytical approach was used to investigate the relationships of PM_2.5-O₃ co-pollution with nonaccidental, cardiovascular, and respiratory mortality levels across 14 cities in China. We first utilized a generalized additive model (GAM) to determine the city-specific associations of PM_2.5 and O₃ with daily mortality. The associations were then combined at the national and regional levels using meta-analysis. To investigate the potential interactions between the two pollutants and cause-specific mortality, we performed stratified analyses by co-
