Abstract
Determination of airborne pollens is essential for understanding tree pollinosis. Therefore, we installed the Durhum standard pollen examiner on the roof of the Wakayama Red Cross Hospital to determine airborne pollens over a long period of time.This paper lists the counts of airborne pollens of Japanese cedar, Japanese cypress and pine from February to May, 1985, and correlates Japanese cedar pollinosis with meteorological data in Wakayama city.Methods of estimating airborne pollens described by several investigators showed a probable high count of airborne pollens as judged by last year's weather phenomena. In Wakayama city in the pollen season this year, Japanese cedar pollens amounted to 577/cm2 and the highest daily count was 58/cm2. A comparison could not be made becuase of lack of previous data in Wakayama. However, on the basis of the yearly change in numbers of patients with Japanese cedar pollinosis at our hospital and the results of measurements by other investigators, the pollen count this year was probably lower than average.We will follow airborne pollens for a long term to help estimate the airborne pollen count in relation to meteorological data.
