The production mechanisms of microcystins, cyanobacterial toxins, were studied: the cyanobacterial biomass, environmental factors and production dynamics of cyanobacterial toxin in Paldang, Gachang, Yeongcheon and Angye reservoirs from March to December, 2007.
Yeongcheon reservoir showed the highest level of microcystins production during the late autumn and winter seasons. Microcystins concentration sharply increased when the dominant species changed from Anabaena sp. to Microcystis aeruginosa. The significant correlation between microcystins and M. aeruginosa was found. This result indicated that M. aeruginosa was the major contributor of microcystins production. Temporal concentration of microcystins correlated inversely with water temperature variation in Yeongcheon reservoir. Very small amount of microcystins were detected at liver, gills, internal organs and muscles of fishes which lived in cyanobacterial blooming Yeongcheon reservoir. This result indicated the dynamic movements of microcystins in reservoir. Due to persisting of cyanobacterial bloom until December, we could not study the destruction mechanism of microcystins.
