Abstract
We installed the standard method on the roof of the University Hospital to determine airborne pollens over a long period of full one year in this city. In the summer peak from the grass-trees such as Cannabis Humulus (1508 grains) and Spring peak Cupressaceae (530 grains) in Spring come to second. In the Autumn peak from the herbs such as Artemisia (1773 grains), Chenopodiaceae (283 grains) subsequently. The relationships among the quantity of airborne pollens montyly and the diffusion patterns of various pollen grains and the pollen quantity are discussed. The highest count after one year was Artemisia (3809 grains) in all total. This paper lists the counts of airborne pollens and will be serviced for pollinosis in this city.
