| 摘 要： | 2008年7—10月在中国科学院大气物理研究所采集气溶胶样品,用离子色谱进行水溶性无机离子分析,并对其组成、质量浓度变化特征、相关性及存在形式、来源解析等方面进行研究。结果显示,整个采样期间,SO42-、NO3-和NH4＋是最主要的水溶性离子,主要以（NH4）2SO4和NH4NO3形式存在;SO42-、NO3-和NH4＋、Ca2＋和Mg2＋的相关系数都较高,具有很好的同源性。NO3-/SO42-质量浓度比值表明,奥运前,固定源（燃煤）对水溶性离子的贡献大于流动源（机动车）,而奥运期间和奥运后则相反。因子分析表明,交通、燃煤、土壤、建筑尘和生物质燃烧源是采样期间北京大气污染的主要来源。

| Abstract: | Aerosols are sampled at Institute of Atmospheric Physics,Chinese Academy of Sciences from July to October 2008.The mass concentrations of water-soluble inorganic ions are determined with ion chromatogram(IC).This aims to investigate the composition,characteristics of mass concentration variation,relevance and form of the main water-soluble inorganic ions and their sources.The results show that SO42-,NO3-and NH4+are the main water-soluble inorganic ions in the aerosol samples,and they are mainly in the form ... |
