大气污染对云冈石窟的风化侵蚀及防护对策
The Erosion of Yungang Grottoes by Air Pollution and its Protection Countermeasures
【摘要】 云冈石窟地区大气污染较为严重 .大气中的污染物主要是SO2 、工业粉尘及粉尘中的金属元素 ,其含量皆严重超标 .在有水份的环境中 ,通过金属离子的催化作用 ,SO2 容易生成H2 SO4或酸性物质 ,再与石质文物表层中CaCO3 作用 ,生成CaSO4·2H2 O ,导致风化侵蚀 .
【Abstract】 The air pollution in Yungang area is severe.The pollution is caused mainly by SO 2 ,industrial dust and metallic elements in it. All of these things exceed quota seriously. Catalyzed by metallic ions,SO 2 easily turns into H 2SO 4 or other acidic things, which will become CaSO 4·2H 2O if they react with CaCO 3 in the surface of rocky relics.
