| 摘 要： | 本文对兰州市不同季节大气颗粒物中水溶性离子的主要理化特性及其与降水的关系进行了研究，认为大气颗粒物中水溶性离子是当地降水中ＳＯ４＾２－，Ｃａ＾２＋，Ｃｌ＾－等主要离子的来源。在１３种被测的水溶物中，ＳＯ４＾２－和Ｃａ＾２＋离子所占比例较高，分别占总离子的３１．４％和２７．８％，年均浓度值为１０．７２μｇ／ｍ＾３和３．９６μｇ／ｍ＾３。同时大气颗粒物中水溶物浓度与ＳＯ２，ＴＳＰ等大气污染物浓度之间也

| Abstract: | The paper studies on the main physics- chemical properties of water soluble ions in atmospheric particulates and their relations with precipitation in different seasons of Lanzhou. The results show that SO42- , Ca2+ , Cl- , and so on were found as water soluble ions in atmosperic particulates and were from local precipitation mainly. Among the 13 kinds of water soluble matters measured, the content of SO42- and Ca2+ ions are the highest and their percentages are 31. 4% and 27. 8%,and the values of annual mean concentration 10. 72mg/m3 and 3. 96mg/ m3, respectively. Besides, the concentrations of TSP water soluble matters are changed with different seasons in similar manner, like that for SO2, TSP etc. |
