Interactive effects of ambient fine particulate matter and ozone on daily mortality in 372 cities: two stage time series analysis.

ABSTRACT:

Objective

To investigate potential interactive effects of fine particulate matter (PM_2.5) and ozone (O₃) on daily mortality at global level.

Design

Two stage time series analysis.

Setting

372 cities across 19 countries and regions.

Population

Daily counts of deaths from all causes, cardiovascular disease, and respiratory disease.

Main outcome measure

Daily mortality data during 1994-2020. Stratified analyses by co-pollutant exposures and synergy index (>1 denotes the combined effect of pollutants is greater than individual effects) were applied to explore the interaction between PM_2.5 and O₃ in association with mortality.

Results

During the study period across the 372 cities, 19.3 million deaths were att
