The quality of ambient air has significant effect on the production and life of human beings, and the PM2.5 is of great importance for the environment and heath. This paper presents the investigation on the regional, seasonal and daily characteristics of PM2.5 in Kunshan, China in 2013 by setting 7 sampling points. The daily average value of PM2.5 varies in a range of 4~366 g/m3 while the annual average value reaches 57 g/m3 with an over-standard rate of 63%. The mass concentration of PM2.5 shows a small regional difference but great seasonal difference. This index is high in winter while low in summer, and is similar in spring and autumn. The total number concentration of particles ranging 0.3 ~10 m in the four seasons is 587/cm3 of which the particles in 0.3~2.5 m account for 99.7%.
