| To determine the content of hazard microcystin (MC) in Han River system and Ecological Ponds in Seoul City and Kyunggi district, a most toxic derivative, microcystin-LR (MCLR) of 15 samples of 7 ponds, 4 rivers and 4 reservoirs during low precipitation and cold season in 2003 were analyzed by ELISA method. With the change of water temperature ($0.4;{sim};21.9^{circ}C$), cyanobacteria including Microcystis aeruginosa dominated the cold phytoplankton community in small ecological ponds such as Kyungbokgung Kyunghyaeru (KBP), Seokchon reservoir (SCR), Yangsoori Ryukgakji (YSS), having the long residence time. Contents of MCLR (the detection limit; $0.05;{mu}g;L^{-1}$) were high in cyanobacteria-rich sites, especially, Microcystis aeruginosa. Total MCLR, cell extracted type plus dissolved type, were $1.39;{mu}g;L^{-1}$ in KBP, $0.55;{mu}g;L^{-1}$ in SCR and $0.59;{mu}g;L^{-1}$ in YSS, in the first sampling having a high temperature (>$20^{circ}C$), while some detected only in YSS during the cold season. As expected, the MCLR content was correlated with Microcystis aeruginosa (r = 0.526 for cell extracted type, r = 0.433 for dissolved type). Therefore, low concentration of MCLR detected in small ponds and Han river system in Seoul metropolitan city and Kyunggi district, maybe hardly affect human recreation activity, especially the drinking water supply. |
