Analysis of Characteristics of Air Particular Matter in The Centre of Guiyang City

Shi Li,Yin Lu,Guo Ke,Jiang Peng(Guiyang Graduate School of Environmental Protection,Guiyang 550002,China)  
This paper analysizes structure character of quality concentration and granularity and chemical composing of particular matter,on the basis of the practical monitoring data.The quality concentration of PM10 of every monitor in winter is higher than in summer because of the more burning coal soot and the stability of air which cause the thin particulate is difficult to diffuse to sky.The proportion of thin particulate is increased distinctly in winter because of the different diffused condition in winter and summer.The diffusing scope is wider in summer than in winter so that the particulate is easy to diffuse to sky and especially for the thin particulate.The primary chemical composing are TC,SO2-4,Si,NO-3,Al and Ca.The quality concentration of PAH of the other four monitors is more in winter than in summer except for the monitor of Tai Ciqiao.The quality concentration of PAH of thin particulate is more than the thick particulate except for the monitor of Jian Cezhan in winter.The PHA accrete to the thin particulat which's quality concentration is more than the thick particulate in winter.
