In order to examine the effect of atmospheric pollution on important cultural objects, two kinds of dyed cloth and silk threads were exposed to air and their changes were examined. The dyed cloths were one silk cloth dyed with benzopurpurine 4B, which is easily affected by sulfur dioxide, and one acetate rayon cloth dyed with diacelliton fast brilliant blue B, which is easily affected by nitrogen dioxide. The color of the dyed cloths was measured by a spectrophotometer before and after exposure (June, 1968,and January, 1969). From the analysis of measured values before and after exposure, degree of the effect was examined. It was thereby found that dyed cloths were affected even by the present degree of pollution by sulfur dioxide and nitrogen dioxide. Fragility of silk threads could not be measured by the present examination lasting about 30 days.
