Epidemiological studies on the subjective symptoms of students affected with photochemical air pollution were made in the periods of Sep. 13, 21, 22, 1972 (School A), and on Oct. 3 (School B) in Osaka.<BR>A statistical analysis following Hayashi's Quantification Theory (Pattern Classification) revealed that the symptoms were to be classified in to 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.<BR>Those three types were either interchangeable or overlapping depending upon the time and day of examination.<BR>Difference in type classification seems to show different quality of photochemical air pollution.
