Abstract
A study to determine changes in the incidence of asthmatic attacks based on the daily record of 15 outpatients residing in the neighborhood of a hospital in Tokyo and afflicted with bronchial asthma of the atopic type was conducted during the 81-day period between November 18, 1969, and February 6, 1970. Meanwhile, an automatic air pollution recorder was installed in that hospital to obtain a running record of the amount of SO2 and suspended particles in air. A comparative study of the changes noted in the above cases confirmed that the incidence of asthmatic attacks tended to rise when the day's maximum value of SO2 gas reached a high level of pollution (over 0.2 ppm), and that such incidence tended to rise even further along with an increase of suspended particles (50% or more absorbance).
