담수의 녹조현상은 각종Cyanobacteria(blue green algae)의 증식에 따른것으로써 이는 단세포 혹은 filament 상태를 유지하면서 광합성을 하며 그람 음성균과 같은 세포벽을 가지고 있는 생명체이다.
이러한 녹조현상은 산업폐기물이나 가정하수 혹은 축산폐수로 오염된 물에 인, 암모니아, 질소 등의 증가와 같은 부영양화에 따른 현상으로 녹조가 심한물을 섭취했을 때 야생동물이나 일반가축에서 폐사하는 예가 있다.

Bloom of blue green algae is major fresh water strike in Korea recently. The organisms occur in eutrophic water of varied organic composition include high nutrient concentration (notably phosphorous, ammonia, and nitrate) which may rise from household, industrial, or livestock farming pollution. Most fresh water include Daecheug lake were contaminate with blue green alge, which were predominated with Microcystis aeruginosa. These can produce toxin "microcustin" with many niological activites. Their productin can be exposed to human and animal caused vital liver damage and death. Until now, there is no toxicopathologic study with microcystin -LR in Korea.
Colonies collected in Okjung-Ho were more or less firm, up to several millimeters, subspeherical and reticulated, elongated, or lobated. Cells tightly aggregated and appeared blackish under high magnification The hepatocytes around central vein were degenerative in mice which were given collected water from Okjung-Ho. Experimentally, female Sprague-Dawley rat and ICR mice were microcystin-LR intraperitoneally with 100 ug/kg body weight. Animals showed clinically lethargy and ruffled hair at 40 minutes post-dosing. Liver were enlarged and dark red beginning 40 miniute after dosing. Mild disassociation and hemorrhage of centrilobular hepatocytes developed. These pathological finding extended to most of the lobules at 80 miniute post dosing. Eosinophilic materials, which were fragment of disassociated hepatocyte, were entrapped in the lung capillaries and renal glomerular capillaries. Ultrastructurally, the Disse space was widened and microvilli of the hepatocyte were losed at 40 minute post dosing. At 120 miniute post dosing, cardiac muscles were degenerative and necrotic.
