1999年11月至2000年4月,在中国第16次南极科学考察往返航线上的海域,采集了22个海洋气溶胶样品,用原子吸收分光法测定了样品中的Cu、Pb、Zn、Cd、Fe、Al、Mn、Cr、V、K、Na、Ca、Mg等13种元素的含量.研究表明气溶胶重金属微量元素的分布具有明显的地理区域性.应用元素富集因子、相关分析和因子分析等方法研究了西太平洋、东印度洋、南大洋、中国南极中山站邻近海域气溶胶中各元素的来源. Twenty two aerosol samples were collected during the Sixteenth Chinese Antarctic Research Expedition from Nov. 1999 to Apr. 2000. These samples were analyzed by AAS for 13 chemical elements, i.e. Cu,Pb,Zn,Cd,Fe,Al,Mn,Cr,V,K,Na,Ca and Mg. The results show that the spatial variability of the heavy metal trace elements in aerosol in the studied area display a significant geographical pattern. Source discrimination of the elements in the marine aerosol was discussed using the methods of enrichment factor, factor analysis and correlation analysis. 国家自然科学资助项目(49976022)
