| 摘 要： | 本文讨论了北京地区气溶胶浓度及其化学特性的年变化。冬季气溶胶的浓度及其化学元素含量高于夏季,一般在12月份出现最大值。气溶胶浓度的变化规律与气象条件有密切关系,亲气元素As、Se、Sb、Br的富集因子远大于10,它们主要来源于燃煤,与人类活动有关。其它元素的富集因子大多小于10或接近于1。 此外,还讨论了气溶胶的垂直分布和城郊气溶胶特性的对比。

| Abstract: | Aerosol concentration in Beijing area and the yearly change of its chemical characters are discussed in this paper. Results indicate that aerosol concentration and the content of chemical elements are higher in winter than in summer, maximum value appearing in December. The rule of aerosol concentration change is closely related with meteorological conditions. The values of enrichment factors of chalcophilic elements As, Se, Sb and Br are much higher than 10. These elements in aerosol mainly come from coal combustion and are of concern to man' s activities. Most of the other elements have the enrichment factor values lower than 10 or near 1.In addition, vertical distribution of aerosol and comparison between the aerosol characters in the city and in the suburbs are also discussed here. |
