Epidemiological studies on the subjective symptoms of students affected with photochemical air pollution were made in the periods of Sept. 13, 21, 22, 1972, and on Oct. 3 in Osaka. A statistical analysis following Hayashi's Quantification Theory (Pattern Classification) revealed that the symptoms were to be classified into three types: Type A with a chief complaint of eye irritation, Type B complaining of cough and sore throat and Type C with nausea, dizziness, and numbness of the extremities. Those three types were either interchangeable or overlapping depending upon the time and day of examination. Difference in type classification seems to show a difference in the quality of photochemical air pollution.
