| 摘 要： | 在2000年2个典型季节分别采集不同尺度的颗粒物样品,分析其中22种无机元素的含量.利用这些数据较详细地研究了北京市颗粒物的元素组成特征.数据分析结果表明,北京市大气颗粒物中的元素主要分为地壳元素、污染元素和双重元素三大类.利用不同污染元素在各种尺度颗粒物中的富集因子,确定了北京市大气颗粒物具有复合型污染的特征.

| Abstract: | The air suspended particles with different sizes were sampled and 22 elements analyzed in Beijing in 2 typical seasons.It was shown that the air suspended particles may be divided into 3 categories,i.e.soil elements from earth crust,pollution elements from coal burning,industry,traffic and households,and other elements from both soil and pollution.The enrichment factors of pollution elements in air suspended particles with different sizes were calculated.It was resulted that the air suspended particles come from not only coal burning,but also from traffic and natural sources. |

| Keywords: | air suspended particles with different sizes element enrichment factor PM\-\{2 5\} PM\-\{10\} TSP |
