摘要
为研究我国广州、武汉、兰州、重庆４城市空气中ＰＭ２．５和ＰＭ１０的污染水平，在这我国４城市分别设一污染点和对照点进行了为期２年的ＰＭ２．５、ＰＭ１０和ＴＳＰ监测。结果表明，空气中颗粒物的污染是严重的，污染点比对照点更甚．对人体健康危害大的ＰＭ２．５普遍超过美国新标准的２－８倍。
In order to study the pollution level of PM2.5 and PM10 in the four cities of Guangzhou, Wuhan, Lanzhou,Chongqing City in China, two kinds of sites in these four cities were selected respectively for monitoring PM2.5, PM10and TSP for two years,one being polluted site and the other reference site. The results show that the particulate pollutionin air is serious,especially in the polluted sites PM2.5, which has more impact on health,is 2 to 8 times greater than thenew standard of USA.
