Abstract: Objective To examine the effect of particulate matter (PM) less than 10 microns in diameter (PM10) and ozone (O3) on daily mortality in Shanghai, China. Methods A generalized additive model with penalized spline function was used to observe the acute effect of PM10 and O3 on daily mortality. Results Higher PMt0 significantly increased the effect of O3 on total mortality,and O3 also increased the effect of PM10 although the estimated increment was statistically insignificant. Conclusion Our findings provide further evidence for the effect of PM10 and O3 on daily mortality.
