Short-term joint effects of ambient PM_2.5 and O₃ on mortality in Beijing, China.

ABSTRACT:

Introduction

In recent years, air pollution caused by co-occurring PM_2.5 and O₃, named combined air pollution (CAP), has been observed in Beijing, China, although the health effects of CAP on population mortality are unclear.

Methods

We employed Poisson generalized additive models (GAMs) to evaluate the individual and joint effects of PM_2.5 and O₃ on mortality (nonaccidental, respiratory, and cardiovascular mortality) in Beijing, China, during the whole period (2014-2016) and the CAP period. Adverse health effects were assessed for percentage increases (%) in the three mortality categories with each 10-μg/m³ increase in PM_2.5 and O₃. The cumulative risk index (CRI) was adopted as a novel appr
