Abstract

The temporal and diel changes of cyanobacterial cell density, species composition, and cyanobacterial toxins (microcystin-RR, -YR, -LR) were examined for the outflow water of Lake Suwa in Japan from May to October, 1998. The highest total cell densities of Microcystis were observed in July and September, when the dominant phytoplankton was Microcystis ichthyoblabe and M. viridis, respectively. Both the species composition and total cell density of Microcystis affected the variation of the concentration of three microcystin variants. Only microcystin-RR(MC-RR) and -LR (MC-LR) were detected in July when Microcystis ichthyoblabe dominated, while microcystin-RR, -YR (MC-YR) and -LR were detected in August and October when Microcystis viridis dominated. The microcystin concentration and the cell density of Microcystis in the outflow water showed diel variations; the ratio of maximum to minimum value was $3{\sim}20$ fold far microcystin concentration, and $5{\sim}31$ fold for cell density. The diel variations of toxin concentration as well as Microcystis cell density was closely related to the diel variation of wind. During the windy period, when higher speeds occurred in the afternoon hours than morning hours, both the cell density of Microcystis and microcystin concentration tended to increase in the morning and decrease in the afternoon. The results of this study suggest that controlling the timing of lake discharge at the floodgate or intake tower can be useful for water resource management with respect to decreasing cyanobacteria biomass within intake water.

방류수내 남조류 세포의 밀포와 종조성 및 독소의 계절별, 일일 변화를 일본 중심에 위치하고 있는 Suwa호의 수문에서 1998년 5월부터 10월까지 조사하였다. Microcystis의 높은 세포밀도가 M. ichthyoblabe가 우점했던 7월과 M. viridis가 우점종으로 나타난 9월에 관찰되었다. Microcystis의 종조성과 총 세포밀도는 3종류의 microcystin의 정성${\cdot}$정량적인 변화와 관련이 있었다. M. ichthyoblabe가 우점했던 7월 동안에는 MC-RR과MC-LR만이 검출되었으나 M. aeruginosa의 개체수 증가와 함께 M. viridis가 우점종으로 나타난 8월부터 10월까지는 MC-YR을 포함한 3종류의 microcystin 모두 검출되었다. 방류수내 Microcystis의 세포밀포와 microcystin의 함량의 일 변화는 바람의 일 변화에 큰 영향을 받았다. 아침에 비해 오후에 바람이 강하게 부는 풍속주기의 조건에서 Microcystis의 세포밀도와 독소의 함량은 아침에 증가하고 오후에 감소하는 경향을 나타냈다. 본 연구의 결과들은 수문이나 취수탑에서 방류시기의 조절은 부영양 호수에서 물을 취수하여 이용함에 있어 원수내 조류의 생물량을 저감할 수 있는 유효한 방법임을 제시한다.
