| Seasonal variations of cyanobacterial toxins (microcystins) in Yeongehun reservoir were studied from March to December, 2007. High level of microcystins production was shown during the late autumn and winter seasons. Total microcystins concentration increased sharply when the dominant species changed from Anabaena sp. to Microcystis aeruginosa. Microcystins-RR and -YR were the main components of the microcystins, whereas microcystin-LR was detected in small quantities. Especially, large amounts of microcystin-LR were detected when standing crops of M. aeruginosa increased exponentially. Total microcystins concentration showed a negative correlation with water temperature. However, total microcystins were lowly correlated with other environmental factors except for water temperature. As a result, this study clearly demonstrated that M. aeruginosa was the main producer of microcystins in Yeongchun reservoir. |
