| 摘 要： | 于2004年1月在中国科学院大气物理研究所气象观测塔院内进行了PM10的采样分析.结果表明,北京市冬季气溶胶浓度有明显的昼夜变化特征,峰值与交通和生活排放源有关;气溶胶元素浓度分析表明,北京市除受局地排放源影响外,还受远距离输送的影响;与1983 年相比,北京市冬季人为污染明显增加, 自然沙尘污染有减少的趋势.

| Abstract: | During January 2004, PM10 samples were collected in Beijing meteorological tower yard. The element concentrations of particle samples were analyzed by XRF method. The results show that aerosol concentrations in winter have obvious diurnal variation. Two peak values occurred in the morning and evening respectively which were affected by traffic and domestic sources. Analysis of aerosol elemental concentration show that Beijing is influenced not only by local source but also remote transportation. Compared with 1983, anthropogenic sources obviously increased and natural sources decreased in winter. |
