摘要
云岗石窟群(山西大同)正在受到大气污染的危害,特别是气溶胶粒子所造成的危害十分显著。本工作采集并分析了该地的气溶胶粒子并研究了其物理化学特性。结果显示,大部分气溶胶是由人为污染产生并且主要集中在粒径较小的范围。细粒子中有较多的酸性污染物并比粗粒子酸性强,这些细粒子对石窟有侵蚀作用。本文还对侵蚀机理进行了探讨并评价了危害程度。
Yungang Grottoes (Datong,Shanxi Province) are being damaged by air pollution, especially by aerosol particulates. Aerosol particulates in this area. were sampled and analized The physical and chemical characteristics of aerosol were studied. The results show that parts of the particulates are caused by anthropoginic pollution and concentrated in the small size range. The particulates have more acidic pollutants with strong acidity and have the corrodibility to grottoes. The corrosion mechanisms were discussed and damage degree was assessed in this paper.
