Abstract Epidemiological data were collected and the Meta-analysis method was used to get the exposure-response functions for health effects especially on mortality of residents under PM10 and PM2.5 pollution in China. As the concentration of PM10 increased 10μg/m3, acute mortality for all-course, respiratory disease and cardiovascular of residents increased 0.38% (95% confidence interval (CI): 0.35%~0.42%), 0.65% (95%CI: 0.35%~0.95%) and 0.37% (95%CI: 0.31%~0.49%), respectively. When PM2.5 concentration increased 10μg/m3, a 0.40% (95%CI: 0.19%~0.62%) increase for all-course mortality, 1.43% (95%CI: 0.85%~2.01%) increase for respiratory death and 0.53% (95%CI: 0.15%~0.90%) increase for cardiovascular death was found. PM2.5 had greater health effects than PM10. Chinese studies reported somewhat lower exposure-response coefficients as compared to internal studies.
