大气环境污染对文物古迹的影响

Relic Corrosion by Air Pollution

国内外多年的研究结果表明，大气环境污染是造成文物古迹损害的重要因素。其中影响最大的是降尘、酸雨、二氧化硫、二氧化氮、二氧化碳和臭氧等。该文根据近年来关于大气环境污染的报导，着重论述了尘埃对文物损害的机理和现象，酸雨对文物的腐蚀过程和反应机理，以及ＳＯ２，ＮＯ２，ＣＯ２和Ｏ３等气态污染物使无机质文物老化、生锈，有机质文物脱色、褪色的原因。

According to many years′ investigation home and abroad,air pollution has made great contribution to relic corrosion.The dust,acid rain,sulphurous dioxide,nitrogen dioxide,carbon dioxide and ozone are the main pollutants.Based on air pollution reports on this area,this paper concluded the reliccorrosion mechanism and phenomenon by dust,the relics erosion and reaction by acid rain,inorganic relic rusting and organic relic decolour by SO2,NO2,CO2,O3,and other gaseous pollutants.
