Abstract
This survey and research was planned in order to grasp on a large scale the extent of spread across the nation of air pollution (which will be called simply photo-chemical smog) caused by photo-chemical reactions. The plan was to observe the leaves of the morning glory for the appearance of visible damage caused by oxidants and ozone which are secondary products of the photo-chemical reaction. The results of the study showed that injuries caused by oxidants were found on the indicator plants in regions reaching all the way from Miyagi prefecture in the north to Kagoshima prefecture in the south along the Pacific coast, all over Shikoku, and in Niigata and Toyama prefectures along the coast of the Japan Sea. Through this survey many Junior High School students, who hold the destiny of the next generation, experienced recognition of photo-chemical smog and the extent to which it causes damage to the plants.
