Abstract :Metal plates (carbon steel, copper) were exposed from 1988 to 1998 every six months under outdoor and indoor conditions at three sites in Niigata prefecture. The outdoor carbon steel plates showed greater penetrations of corrosion (μm) than those of indoor plates. The amount of corrosion product (mg/200c㎡) and penetration of corrosion varied seasonally, especially in cold season (from October to March) in indoor exposure test, they remarkably increased in Niigata city. The outdoor carbon steel penetrations of corrosion correlated with SO_4^<2->, Cl^-, Na^+, K^+, Ca^<2+>, Mg^<2+> ions. The penetrations in Niigata prefecture were greater than those in the area along the Pacific Ocean. Copper mass loss in weight was much smaller than that of steel.
