Results Using a symmetric bi,directional control sampling approach, the results obtained from a conditional logistic regression model with four reference periods after controlling for weather conditions showed that the OR of non,accidental mortality associated with each 10 ?g/m3 increment of PM10, SO2 and NO2 over a 48,hr moving average were 1.007(95%CI 1.003-1.011),1.011(95%CI 1.001-1.021),1.010(95%CI 1.000-1.020)respectively. Similar associations were observed between mortality of cardiovascular diseases and PM10, mortality of respiratory diseases and NO2. Also, PM10 was associated with mortality in a sensitivity analysis. Conclusion The acute effect of air pollution on mortality of the general population was established in Zhabei district of Shanghai.
