摘要
采用等离子体原子吸收光谱法(ICP-AES)分析了成都市十里店地区大气气溶胶的元素组成,并运用富集因子和因子分析方法对气溶胶的元素富集状况及其来源进行了解析。结果表明:该地区大气气溶胶中Ca,Cu,Zn,As,Pb,Cd和Hg等有毒有害元素富集程度高,对人体和环境危害大。气溶胶主要来源于地面扬尘、冶金化工尘、燃煤和燃油尘。
In this paper, the element components of the atmospheric aerosols in the Shilidian area of Chengdu are analyzed by the inductively coupled plasma atom emission spectroscopy (ICP-AES) and the source apportionment of the aerosols is preliminarily analysed by enrichment factor and factor analytical method. The results of research show that the enrichment of poisonous and unwholesome elements such as Ca, Cu, Zn, As, Pb, Cd and Hg in the aerosols is high and that the aerosols mainly come from the dusts of ground, metallurgy and chemical industry, and the dusts by coal burning and oil burning.
