| 摘 要： | 用等离子发射光谱法对2000年10月至2001年8月上海市4个采样点大气PM2．5中的Cu,Zn,Pb,As等元素的浓度进行分析，研究表明，在上海市不同代表城区大气PM2．5中的元素浓度呈现一定的分布特征，存在一定的季节变化规律，计算元素的富集因子，并与国内外城市颗粒物中元素 的富集因子比较，表明Cu,Zn,Pb,As等元素在上海市大气PM2．5中的富集程度与它们在其他城市大气PM2．5中的富集程度基本处于同一水平。

| Abstract: | The concentrations of elements Cu, Zn, Pb, As, et al in PM 2.5 were measured using inductively coupled plasma(ICP). Samples were collected at four sites in Shanghai during period from October, 2000 to August, 2001. The result showed that the concentrations of the elements of interest in different functuonal zones had different distribution feature. Moreover, a seasonal variation was also found. After caculating the enrichment factors of the elements in PM 2.5 of Shanghai atmosphere and comparing them with other cities', enrichment of these elements was at nearly the same level as other cities'. |
