Air pollution in Gifu City was obserbed by the filter paper method from 1963 to 1965. The measurement on the variation of sulfur oxid and nitrogen oxid value was performed at eight places. It was found that the mean value of sulfur oxid was 0.31mg SO_3/day/100cm^2 and the value range was 0.01-0.71mg SO_3/day/100cm^2. The mean value of nitrogen oxid was 0.063mg NO_2/day/100cm^2,and the value range was 0.017-0.192mg NO_2/day/100cm^2. In Gifu City, we measured the smog states on the 10 th and the 15 th Jun. 1963. On the 10th, SO_2 was measured more than 0.2 ppm. But on the 15 th, SO_2-concentration was very low, and CO_2-concentration was very high. It was caused by burnning the wheat straw, so we call "Rural Type Smog". These smog states were caused by calm weather.
