ACID DEPOSITION AND MATERIAL DAMAGE IN EASTERN ASIA

摘要

The impact of local wet and dry deposition of acid compounds was investigated by means of exposure of different materials, copper, bronze, marble etc. under indoor and outdoor conditions. Different corrosion products are formed, depending on the local pollution climate. Especially the ratio between SO2 and NOx is important. Rates of damaged have been assessed and are proven to be significant. [References: 4]
