서울에 있어서 空中花紛의 飛散時期와 飛散量의 春秋變化

A Study on the Distributed Time and the Seasonal Change of the Amount of the Airborne Pollens in Seoul

The airborne pollens were investigated by 11 pollen traps in Seoul from September to November, 1986 and from March to May, 1987. There were 25 families and 36 genera of which pollens were observed, the amount of airborne pollens was most in May, and least in November. Distribution patterns of ariborne pollens were that of herbs, such as Ambrosia, Artemisia, Humulus, and persicaria in fall, and that of trees, such as Alnus, Salix, Corylus, Pinus, Platanus Betula, and Quercus in spring. From the viewpoint of regional distribution, pollens were much observed at a residential section and an industrial area in fall, and at a park region in spring.
