Air-borne pollen is known as one of the major causal agents to respiratory allergic reactions.
The daily number of pollen grains was monitored using Burkard volumetric spore traps at
eight locations including Seoul and Jeju during 1997-2005. Pollen grains were observed
throughout the year especially from February to November. They showed similar distribution
patterns of species among locations except Jeju, where Japanese cedar vegetation is uniquely
found. The peak seasons for pollen grains from trees, grasses, and weeds were from March to
May, May to September, and August to October. Tree pollens were mainly composed of pine,
oak, alder, and birch. Weed pollens were mainly from Japanese hop, sagebrush, and ragweed.
The diameter of pollen grains, which has a typical range of 20~60 ㎛, has close relationship with
allergenicity. The allergenicity of trees and weed pollens is higher than that of grass pollens in
general. Daily fluctuations in the amount of pollens have to do with a variety of meteorological
factors such as temperature, rainfall, and the duration of sunshine. Temperature and rainfall are
especially decisive in determining pollen concentrations. Ten weather elements that are thought
to affect the concentration of pollens are used to develop equations for the pollen forecasts.
Predictive equations for each pollen species and month are developed based on statistical
analyses using observed data during the last 5 years in Seoul through a co-work with the
Committee of Pollen Study in Korean Academy of Pediatric Allergy and Respiratory Diseases
and National Institute of Meteorological Research.
