dc.description.abstract | In order to understand behaviors of heavy metals around the artificial Lake Shihwa in the vicinity of Kyunggi Bay in Korea in relation with huge environmental changes according to construction of huge artificial lake, water samples were collected from Lake Shihwa and its tributaries from 1996 to 1997 and anlyzed. Due to extreme pollutant discharge from various kinds of anthropogenic sources such as the Banweol and Shihwa Industrial Complexes and cities, the Lake Shihwa and its tributaries has been polluted in waters and sediments with various heavy metals. The enrichment factors of particulate heavy metals in water of streams and storm sewers were very high. All of the heavy metals observed in the waters showed relatively high temporal and spatial variatiohs. In surface waters of the lake during the desalination after the dike establishment, spatial distribution of heavy metal concentrations were mainly controlled by various biogeochemical factors as well as input of industrial and municipal wastewaters, however, physical mixing was minor factor. Pb and Co showed a strong affinity to particle phase, however strong affinity to dissolved phase were dominated in Ni, Cu and Cd. After construction of dike, the anoxic conditions developed by pollutants loading, and also the lack of mixing was evident from the rapid decrease in DO. The vertical distributions of dissolved and particulate heavy metal concentrations showed dramatic changes at the oxic/anoxid boundary. | - |
