Effects On Materials

Acid precipitation can damage manmade materials such as buildings, metals, paints, and statuary (Glass, Glass, and Rennie 1980). For example, Kucera (1976) has reported data on the corrosion rates of unprotected carbon steel, zinc and galvanized steel, nickel and nickel-plated steel, copper, aluminum, and antirust painted steel due to sulfur dioxide and acid precipitation in Sweden. Corrosion rates are higher in polluted urban atmospheres than in rural atmospheres because of the high concentrations of airborne sulfur pollutants in urbanized areas. Economic damage is significant in galvanized, nickel-plated, and painted steel and painted wood.
