Precipitation Chemistry and Corrosion of Metal Plates


From April 1991 to March 1992, precipitation samples were collected in Nara City and eight other sites in Nara Prefecture. Carbon steel plates were exposed to the open air outdoors in eleven sites in the prefecture. Precipitation chemistry was assessed in terms of ionic composition and concentration. The corrosion of sample plates was also observed in relation to precipitation chemistry as well as major air pollutants.
