Abstract: This project is part of the Swedish International Development Co-operation Agency (Sida) funded Program on Regional Air Pollution in Developing Countries (RAPIDC). The Program is managed on Sida's behalf by the Stockholm Environment Institute (SEI) and the corrosion project is coordinated by Swerea KIMAB AB. Corrosion attack after one (2002-2003 and 2005-2006), two (2002-2004) and four (2002-2006) years of exposure are presented for 12 test sites in Asia (India, Vietnam, Thailand, Malaysia, and China including Hong Kong) and four test sites in Africa (South Africa, Zambia and Zimbabwe). Materials exposed are carbon steel, zinc, copper, limestone and paint coated steel. At each test site, the environment is characterized by SO2, NO2, HNO3, 03, particles, amount and pH of precipitation, temperature and relative humidity. Preliminary results are also given from the enlargement of the network (2006-) by inclusion of five new test sites in Asia (Taj Mahal/India, Iran, Nepal, Sri Lanka and Maldives) and two new test sites in Africa (Mozambique and Tanzania). SO2 is the most important parameter but acid rain is also important for all materials while HNO3 show correlation to corrosion of zinc and limestone, much similar to the situation in Europe. Attempts to predict corrosion values using dose-response functions developed in Europe have failed, especially for limestone.
