Effects of Ambient O₃ on Respiratory Mortality, Especially the Combined Effects of PM_2.5 and O₃.

ABSTRACT:

Background

In China, the increasing concentration of ozone (O₃) has emerged as a significant air pollution issue, leading to adverse effects on public health, particularly the respiratory system. Despite the progress made in managing air pollution in China, it is crucial to address the problem of environmental O₃ pollution at present.

Methods

The connection between O₃ exposure and respiratory mortality in Shenyang, China, from 2014 to 2018 was analyzed by a time-series generalized additive regression model (GAM) with quasi-Poisson regression. Additionally, the potential combined effects of fine particulate matter (PM_2.5) and O₃ were investigated using the synergy index (SI).

Results

Our findings indicate that each
