| 摘 要： | 利用兰州市冬季大气颗粒物Anderson分级采样器和石英分级采样器的资料,采用改进的三次样条插值方法分离出PM2.5,研究兰州市PM2.5PM10的污染水平、PM2.5占PM10和TSP的比例,并比较兰州市PM2.5和PM10在国内的污染水平.结果表明:兰州市冬季PM2.5和PM10的污染严重,PM2.5在大气颗粒物中的质量浓度相对很高,PM2.5的污染和危害值得重视.

| Abstract: | PM2.5 are classified from data collected by Anderson cascade sampler and quartzose cascade sampler, using the piecewise cubic Hermite interpolation method. Then the pollution level of PM2.5 and PM10, the proportions of PM2.5 over PM10 are studied. Moreover, the pollution level of PM2.5 and PM10 in Lanzhou is compared with other cities in China and the results show that in Lanzhou in winter the pollution of PM2.5 and PM10 is very serious, air pollution is mainly caused by PM2.5, the proportion of PM2.5 in atmospheric particle is high, the pollution and harm of PM2.5 is worthy of recognition. |
