1998年南极中山站海洋气溶胶的化学组成及其来源判别

Abstract

从1998年3月7日至1999年3月2日历时12个月,在南极中山站连续采集52个海洋气溶胶样品,提供全部样品的13种化学元素铜、铅、锌、镉、铁、铝、锰、铬、钒、钾、钠、钙、镁含量的实测值.研究表明中山站气溶胶化学成分的含量具有季节性变化的特征.通过富集因子、相关分析、因子分析等方法判别中山站气溶胶化学成分的来源.

Fifty two aerosol samples of 6~7 d duration were collected from March1998 through March1999 at the Zhongshan Station in Antarctica. The content of 13 chemical elements is presented:Cu,Pb,Zn,Cd,Fe,Al,Mn,Cr,V,K,Na,Ca and Mg. The study results demonstrate that the content of elements in marine aerosol at the Zhongshan Station appeared to be characteristics of seasonal variation, which were related to features of meteorological element. Meanwhile sources of the elements in the marine aerosols are discriminated using methods of enrichment factor, correlation analysis and factor analysis.
