Description
Summary:This study was performed to evaluate characteristics of algal occurrence in Lake Paldang. Chlorophyll a concentration was highest during spring, based on weekly measurements from 2006 to 2008, which revealed a different trend compared to the data before 2000 that showed the highest level during summer. Total algae cell quantity was also highest during spring, based on monthly data. Overall, Bacillariophyceae was dominant and represented 87% of total algae cells and occupation was more significant during spring and winter. Cyanophyceae was dominant during summer. 2-MIB and geosmin originating in algae which caused odor problems was high in July 2008, and more research on the relationship between algae and production of odor causing material is needed. 본 연구는 팔당호내 조류의 발생특성 파악을 위해 수행되었다. 2006-2008년 매주 측정한 자료를 토대로 클로로필-a 농도는 봄철에 가장 높은 것으로 조사되어 여름철에 가장 높게 조사되었던 2000년 이전 자료와 다른 결과를 나타내었다. 월간 측정 자료에 의하면 2008년 총 조류개체수도 봄철에 높게 나타났다. 전체적으로 규조류가 우점하였으며 연평균값으로는 총 조류개체수의 87%를 차지하였으며, 특히 봄과 겨울에 우점정도가 높았다. 하절기의 경우 특정시기에 남조류가 우점을 차지하였다. 조류에서 기인하는 냄새 유발물질인 2-MIB와 geosmin은 2008년 7월에 특히 높게 나타났는데 조류와 냄새물질 발생간의 상관관계에 대한 보다 많은 연구가 필요하다.
