Abstract
Ash samples were collected using eight classifications of atmospheric particulate matter sampler in two temples located in Jiaozuo city. Concentration of particles of different grain size was measured and analyzed. The results indicated that particulate mass concentration was significantly increased in the burning incense air. The maximum concentration of PM9.0 and PM2.1 were 9 times than that of the national air quality secondary standard (PM9.0:0.15mg/m3) and 13.5 times for American standard (PM2.1:0.065mg/m3), respectively. The size distributions of particles from incense burning overall showed “U” model. Range of size distribution of fine particles concentrated in 1.1~0.43µm, or the total 39.36%~50.14%.
