Methods The daily death data, the meteorological data and the air pollution data from January 1 to December 31, 2003 were collected, the time-series analysis by generalized additive model was used, controlling for long-term trends, seasonal patterns and meteorological variables (temperature, humidity). Results An increase of 10 ?g/m3 of SO2, NO2 and PM10 corresponded to 0.4%(0.1%-0.8%), 1.3%(0.2%-2.4%)and 0.4%(0.2%-0.6%)increase of cardiovascular mortality respectively in Beijing. Conclusion The results of the present paper show that the current level of air pollution is a risk factor for cardiovascular mortality in Beijing.
