| 摘 要： | 在北京市不同地点采集４６ 个降水样品，测定了其中汞和其它元素的含量，通过主成分因子分析进行来源识别分析． 结果表明，降水中元素主要来源于燃煤、扬尘、燃油和特殊污染源．降水中汞（Ｈｇ）可能主要是土壤中汞挥发到大气中，经氧化后随降水降到地面．

| Abstract: | rain samples were collected in Beijing and the content of the chemical elements,including Hg were detected.With the tested data the sources of the Chemicals were identified by principal component factor analysis.The elements in rain were orderly come from the coal burning,the dust,and the combustion of gasoline and other sources.The total mercury in rain was mainly from the source probably related with volatilization of Hg from soil. |
