摘要
分析了上海市区5个采样点,1986年至1987年连续12个月(每月60～100小时)的大气颗粒物样品中的11种金属元素含量。结果表明,市区各功能区之间,以及各个季节之间,元素分布特征有明显差异;细粒子中的重金属元素主要受局部地区工业源和气象条件的影响;与其它城市相比,上海市大气颗粒物中的重金属元素含量高数倍;通过粒径—成份分析以及富集因子分析,探讨了这些元素的来源。
Analysis of the contents of eleven metal elements in the atmospheric participate samples from 1986-1987 at five sampling sites in Shanghai. The results showed that the characterisitics of the elements were quite different from site to site and season to season; the heavy metal elements mainly contained fine particles and affected by local industrial sources or meteorological factors, while alkaline metal elements, such as Na and Al were coarse particles. In comparison with other cities in China, the contents of metal elements in
Shanghai were higher. The analysis of sources of metal elements have been presented.
