摘要

Airborne pollen is known as one of the major causal agents to respiratory allergic reactions.Daily number of pollen grains was monitored using Burkard volumetric spore traps at eight locations including Seoul and Jeju island in the Republic of Korea during 1997-2009. Pollen grains were observed throughout the year especially from February to November. They showed similar distribution patterns of species among locations except in Jeju, where Japanese cedar vegetation is uniquely found. Peak seasons for pollen grains from trees, grasses, and weeds were March to May, May to September, and August to October, respectively. Tree pollens were mainly composed of pine, oak, alder, and birch. Weed pollens were mainly from Japanese hop,sagebrush, and ragweed. Statistical analyses including simple correlation and multiple regression were conducted between the day-to-day fluctuations of pollens and various meteorological variables so that we can estimate the increase of pollens as the consequences of the climate change. Diameter of pollen grains, which has a typical range of 20～60μm, has close relationship with allergenicity. Pollens from trees and weeds have higher allergenicity than those from grasses in general. The allergenicity of the pollen grains is observed to depend on the concentration of atmospheric carbon dioxide. The elevated level of pollen allergenicity together with the increased number of airborne pollens can be more harmful to the allergic patients in the future.
