For investigating the impact of PM2.5 and PM10 during dust weather and non-dust weather on cardiovascular and cerebrovascular diseases, this paper used time series method of nonparametric generalized additive model (GAM) by controlling the long-term trend, "week effect", the influence of meteorological factors, to establish the relationship (RR) between the concentrations of PM10, PM2.5 during dust weather and non-dust weather and between the number of inpatients contracting cardiovascular and cerebrovascular diseases from 2006 to 2010 in Beijing on the basis of PM10 and PM2.5 classification, and then compare the different effects on cardiovascular and cerebrovascular diseases between dust pollution and haze pollution. The results have shown that there was significantly associations between PM10, PM2.5 and the number of inpatients contracting cardiovascular and cerebrovascular disease with a lag of 0~2d,the RR value of PM2.5 and PM10 were relatively close; During the non-dust weather, there were dose-response relationship of RR between PM2.5, PM10 and the number of contracting cardiovascular and cerebrovascular diseases. RR increased as the PM2.5 concentration rose. Firstly RR increases and then decreased gradually as the PM10 concentration rose. On the same PM10 exposure level, RR of dust weather was lower than that of non-dust weather. Exposed to the same PM2.5 concentration, RR of sandstorms and non-dust weather was close. With respect to the dust weather, there was also lag effect for haze pollution affecting cardiovascular and cerebrovascular diseases, as haze worsened, cardiovascular and cerebrovascular diseases on the population experienced greater harm.
