Aerobiological Study of Pollen and Mold in the 10 States of Korea / 소아알레르기및호흡기학회지

ABSTRACT

PURPOSE: As outdoor allergen, pollen and mold are increasely drawing attention all over the country in Korea. The peninsula is located in a temperate zone and has four distinct seasons. In this study, we described the seasonal variation of the pollen and mold distributions in Korea, which may be used to evaluate the pollenosis prevalence for the first time. METHODS: Rotorod samplers were installed on the 10 stations at each state in Korea. Outdoor allergens were collected daily in each station from July 1, 1997 to June 30, 1999. After staining they were identified, counted and recorded with the weather in each state. RESULTS: The pollens were found in the beginning of February through the middle of December. The earliest pollen was found from Pusan which is a south region, and followed by Chonju, Daegu which are midsouth. The peak season for pollen was from the end of April to the middle of May(major pollen Tree, Grasses), the second peak was depicted from the end of August to the middle of September (major pollen sagebrush, ragweed) the outdoor molds were largely collected from the July to the middle of October. Cladosporium and Alternaria were prevalent all year round and Ascospores of Leptospheria was peak in monsoon season. CONCLUSION: The pollens were found during the whole year except from middle of the December through the middle of the January. Molds were found all year round.
