2006～2007年,利用大容量气溶胶采样器在台湾海峡采集79个大气气溶胶样品.采用ICP-MS分析法测定了样品中Pb、Cu、Cd、V、Zn、Fe和Al等金属元素的含量.分析结果显示,台湾海峡大气微量金属含量呈现出明显的季节变化,对大部分元素而言,含量最低值出现在夏季,而最高值出现在冬季,气溶胶中微量金属的含量变化与海峡的气象条件等因素有关.通过富集因子、相关性分析和因子分析,对微量金属的来源进行了判别.台湾海峡大气微量金属的来源特征为:Cu、Pb、 Cd、V主要来自污染源,而Al、Fe、Zn则主要来自地壳源.比较和分析了台湾海峡海域微量金属的大气与河流输入, Cu和Zn的大气输入低于九龙江和闽江的输入,而Pb、Cd的大气输入则超过了这2条河流的输入.

79 marine aerosol samples over the Taiwan Strait were collected using high volume aerosol sampler during 2006 and 2007.All the samples were analyzed for Cu,Pb,Cd,V,Zn,Fe,Al using atomic absorption spectrophotometer.The results showed that the contents appeared to be characteristics of seasonal variation,as for most of metal elements,its contents were the highest in summer,and the lowest in winter.The contents varied with the features of meteorological element and so on.The sources of atmospheric trace metals were distinguished from enrichment factor,correlation analysis and factor analysis,it showed that Cu,Pb,Cd,V came mostly from anthropogenic sources,and Al,Fe,Zn mostly from crustal sources.The atmospheric input and river input of trace metals to Taiwan Strait were compared and analyzed.It showed that the atmospheric inputs of Cu and Zn were lower than the Jiulongjiang River and Minjiang River inputs,and the atmospheric inputs of Pb and Cd were higher than the river input.
