| 摘 要： | 为研究西安市南郊地区采暖期大气颗粒物PM2.5的污染浓度及水溶性成分,使用颗粒物采样器于2009年1月6日～2009年2月15日进行PM2.5采样.将24 h分为8个阶段,每天3 h定时采样.结果表明,西安市南郊地区采暖期PM2.5明显污染,24 h中PM2.5污染状况最严重的时段为21:00～23:59;PM2.5中NH+4、NO-3和SO2-4是其最主要的水溶性组分,在PM2.5中的平均质量混合比分别为10.225%、13.698%和15.650%,三者在PM2.5中质量混合比最高的时段分别为06:00～08:59、03:00～05:59和18:00～20:59.

| Abstract: | The purpose of this study was to investigate the mass concentration and water-soluble components of atmospheric particulate PM2.5 during the heating period in the southern suburbs of Xi'an.PM2.5 were collected periodically everyday at three-hour intervals from Jan.6,2009 to Feb.15,2009 by sampling instrument.The results showed that PM2.5 pollution was obvious during heating period in the southern suburbs of Xi'an,the most serious time interval was from 21:00 to 23:59;NH+4,NO-3,SO2-4 were the main water-solu... |
