| 摘 要： | 化学组成、微量元素、X-射线粉末衍射、红外吸收光谱、扫描电镜分析等研究，显示合肥市各个取样点大气颗粒物组成基本稳定，矿物组成为：伊利石、石膏、绿泥石、石英、长石、方解石、白云石、无定型非晶质物，具有异常的钙、钴、铜、铅、锌含量，主要为微米粒级颗粒，综合分析结果揭示合肥地区大气颗粒物主要源于水泥工业和交通造成的污染，部分来源于地面扬尘和工业窑炉。大气降尘中较多石膏（大于10%）的存在，说明大气SO2污染比较严重。

| Abstract: | Components of atmospheric particles were studied by XFR, XRD, IR and SEM, and the results show that they are basically the same in different parts of Hefei City. Mineral components of atmospheric particulates include illite, gypsum, chlorite, quartz, feldspar, calcite, dolomite and noncrystalline substances. There are abundant Ca, Pb Co, Cu and Zn in the particulates. Analytical results demonstrate that atmospheric particulates come mainly from concrete industry and traffic, and partly from air dust and soot of industrial stoves in Hefei City. There exists plenty of gypsum in atmospheric particulates, which account for the fact that SO 2 pollution is relatively severe in Hefei area. |
