Concentration of sulfur oxides and nitrogen dioxide in atmosphere was measured by alkaline filter paper method in summer (June 1968) and winter (January 1969) at 100 places in Kyoto, including the grounds of shrines and temples in which the designated Important Cultural Properties were placed. A rather higher concentration of both sulfur oxides and nitorogen dioxide was generally observed in winter than in summer. Further effect of these air-pollutants on metallic luster of these Properties was investigated, and the rate or decrease in metallic luster was about 10% lower on the average in winter than in summer. Although it was supposed that the weather conditions might be largely responsible in decreasing the metallic luster, correlation between the concentration of sulfur oxides and the rate of decrease in metallic luster was observed generally in both summer and winter (correlation coefficient found, 0.458 in summer, 0.416 in winter). There was no correlation between the concentration of nitrogen dioxide and decrease in the luster of metals (correlation coefficient found, 0.180 in smmer, 0.138 in winter).
