The content of TSP was analyzed in this paper,which was got from seven districts of Chongqing,in which Beibei District(Jinyun Montain) is background area.The results showed that the annual average value of TSP in the Yuzhong and Beibei lower than the Standard(Ⅱ)( 0.2mg/m3);the annual average value of TSP in the Jiulongpo,Yubei,Jiangbei,Nanan,Shapingba higher than the Standard(Ⅱ)( 0.2mg/m3).This implied the air pollution was serious in Chongqing.Five kinds of heavy metals in the TSP were analyzed by ICP-AES.It showed that the tiptop average value of content of Cd,Pb,Zn,Cu,Cr and the values is 0.0121μg/m3(Jiulongpo)、 0.4632μg/m3(Jiulongpo)、 1.5225μg/m3(Yuzhong)、 0.1296μg/m3(Shapingba)、 0.4719μg/m3(Shapingba),respectively.Based on the method of enrichment gene,the result showed that the enrichment coefficient of 5 kinds of heavy metals in the TSP greatly higher than 10,even 1-3 number grade.This can conclude that the pollution of heavy metals in the TSP come from the human activity.
