Abstract:
Objective To analyze quantitatively the acute effect of serious air pollution on cardiovascular mortality in Taiyuan, a typical city where the air was heavy polluted in China. Methods Mortality data in 2004 were from Taiyuan mortality surveillance system, meteorological data and air pollution data were from Taiyuan Meteorological Bureau and Taiyuan Environmental Monitoring Station, respectively. Generalized Additive Model (GAM) extended Poisson regression was used to examine the relationship between air pollution and mortality in Taiyuan, and controlling with time trends, weather and the day of week. Nonparametric conditional bootstrap was used to adjust the concurvity and reduce estimation error. Results The average concentration of PM10, SO2, NO2、CO in 2004 were 173.55, 79.34, 23.03, 2 214.59 ?g/m3 respectively. The median daily count of death for cardiovascular disease in 2004 was 7/daily. Pearson correlation analysis between SO2, CO, PM10 and temperature showed that the association in order were SO2 (r=-0.701 6,P
