Abstract

There has been increasing number of patients with asthma, rhinitis, and conjunctivitis due to the atmospheric pollution and global warming. In this study, we investigated daily observed number of pollens to establish a standardized method for the impact analysis of the climate changes on the number of daily pollens in Korea. Daily observed allergenic pollens of trees, weeds, and pine were analyzed during the period of 1998 to 2010 (except 2006) in Seoul, Busan, Daegu, Gwangju, Gangneung, and Jeju. They increased in large cities including Seoul during the last 12 years and the long-term trend may continue in the future. Daily concentration or amount of pollens was highly correlated with weather variables. Positive correlation was found between air temperature and the pollens although different relationships existed for different locations. Chill days were utilized to estimate the length of the flowering or pollen period. The pollen period of trees was shorter in the field when the winter temperature was low. This approach may be utilized to determine the quantitative change in length of the pollen season in the future.

세계적으로 기후변화에 의한 온난화 현상과 대기오염증가와 아울러 알레르기 유발성 꽃가루의 증가로 천식, 비염, 결막염 등 알레르기 질환 환자가 급증하고 있다. 본 연구에서는 꽃가루 농도의 변화에 따른 영향을 체계적으로 표준화하기 위하여 한국의 꽃가루 특성을 분석하였다. 관측된 꽃가루는 1998~2010년(단, 2006년은 제외)의 알레르기를 일으키는 소나무, 수목류(소나무 제외), 잡초류를 서울, 부산, 대구, 광주, 강릉, 제주지역을 중심으로 분석하였다. 꽃가루는 지난 12년간 서울을 포함한 대도시 지역에서는 장기적으로 증가하고 있으며, 앞으로도 장기적으로 증가할 것으로 판단된다. 꽃가루 농도와 기상요소는 매우 높은 상관관계가 있으며 특히 기온과 양의 상관관계를 가진다. 지역별로는 꽃가루 농도와 기상요소는 서로 다른 상관관계를 가진다. 꽃가루농도에 영향을 주는 기상요소 중저온누적도와의 관계를 이용하여 꽃가루 개화기간의 예측식을 도출하였다. 분석결과로부터 수목류의 경우, 충분히 낮은 기온이 만족되면, 개화기간이 줄어드는 결론을 얻었다. 이 모형에 의한 결과로부터 알레르기 유발 꽃가루의 유행시기변화를 생물계절모형으로 예측 가능함을 판단할 수 있다.
