Corrosion damage due to acid deposition has been studied by exposing samples of galvanized steel, nickel and latex house paint (with and without carbonate extender) at three test sites in the Greater Los Angeles area and in Salinas, CA. Atmospheric corrosion rate monitors (ACRM) with zinc or nickel sensors facing the sky or the ground have also been exposed. The ACRMs provide a continuous record of the time-of-wetness and atmospheric corrosion rates. The results of the field tests show that corrosion rates for galvanized steel are very low with the lowest rates being observed in the winter months. The higher corrosion rates observed during the summer are considered to be caused by nitric acid produced by photochemical oxidation of NO{sub x}.
