Abstract

In a variety of environmental pollution problems, excessive air quality decline caused by PM2.5 has become a hot topic of social concern at home and abroad, PM2.5 concentration over the adverse effects on human health has been generally recognized, but on PM2.5's influence on the population, social and economic factors hidden after the population health risks are not seen in china.[1] Since 2013, haze has becoming more and more thick in the north area of china. Haze affects our daily life. So it's urgent to find the relationship between the haze and pm 2.5.This paper aims at finding the relationship based on AHP. Pm 2.5 includes different kinds of elements such as Pb, Mn, Sb, As, Cd, Co, Cr.....and materials like PAHs. We take some typical elements and materials to approach. The whole order of importance of pm2.5's components is:(PAHs,Pb)>(As,Cr) >(Cd,Co)>(Mn,Sb,SO42-).After establishing health evaluation coefficient and related layers, we can get the typical cities order: Beijing>Zhengzhou>Urumqi>Qinhuangdao>Xian>Anshan>Tianjin>Lanzhou>Yinchuan.
