摘要
从 2002 年12 月到2003 年 2 月,利用 8 通道采样器对上海吴淞地区进行 3 个月的大气气溶胶 PM10(空气动力学直径小于 10μm 的颗粒 )的采样。使用质子激发 X 射线荧光 (PIXE)分析方法进行了多元素质量浓度测定,然后对获取数据进行主成分分析,讨论了吴淞地区 8 个风向采集的 PM10 中含有的主要化学元素成分和可能的来源。
Atmospheric aerosol samples (PM10) were collected using Automated Cartridge Collection Unit (ACCU) and TEOM1400 sampler in Wusong District of Shanghai City during the period of December 2002 - February 2003. The elemental concentrations of PM10 were determined by Proton Induced X-ray Emission (PIXE) technique, and the results were analyzed by principal component analysis. The elemental component factors from eight directions of pollution sources are also presented and discussed in detail.
