| 摘 要： | 为了调查兰州市空气中颗粒物PM2.5的污染水平,于2008年夏秋、冬季在兰州市一交通主干道附近使用大气采样仪采集了32个样品。结果表明:兰州市PM2.5、PM10的污染状况严重,超标率分别为32.3～167.7%和23.1～480%;对人体和环境影响较大的PM2.5占PM10的比例范围从62.10～77.41%,而且呈现逐年增加的趋势。我国目前对于PM2.5的相关控制标准尚处于论证、试点研究阶段,使得对它的控制越发困难,应当引起公众和相关部门的高度重视。

| Abstract: | 32 PM2.5 and PM10 air samples collected in summer,autumn and winter of 2008 and early 2009 were analyzed to assess the air quality of Lanzhou city.The results showed that over the monitoring period,PM2.5(with USA air quality standard) and PM10 were beyond the standard.The exceeding rates of the twoparticls were from 32.3% to 167.7% and 23.1% to 480% for summer,autumn and winter respectively.The proportion of PM2.5 in PM10 was from 62.10 to 77.41% and appeared the rising trend.The PM2.5 standard in air quality in China is under discussion,so it is dramatically hard to put it under control. |
