摘要:

连续三年(1998—2001年)采集了南极中山站的气溶胶样品,利用中子活化(INAA)分析其元素组成,采用作图法对元素的来源进行分析。结果表明除南极中山站气溶胶中的Na,Cl,Mg,Ca,Sr,Br,I和Rb等8个元素主要来自海洋,Al,Sc,Fe和Mn等4个元素主要来自陆源,而Se,Co,Sb,Zn和Cr等5个元素呈现出高度的富集,属于重金属污染特征元素,这可能与站区发电、垃圾焚烧、污水处理、车辆运行和加工制作等站务活动有关。

Abstract:

Three years of bulk,high-volume aerosol samples were collected at Zhongshan Station in East Antarctica. Full name (INAA),(SEM-EDX) and (TEM-EDX) were applied respectively to study chemical species and physical features of aerosols. A graphical technique was applied to the INAA data. Results showed that Na,Cl,Mg,Ca,Sr,Br,I,Sr and Rb were marine elements while Al,Sc,Fe and Mn were crustal elements. Five elements (Se,Co,Sb,Zn,Cr) were highly abundant in the station aerosols either to marine or crustal sources,...
