시화호와 주변 환경의 중금속 분포 특성과 오염

Abstract

In order to understand distribution characteristics of heavy metals around the artificial Lake Shihwa in the vicinity of Kyunggi Bay in relation with huge environmental changes, environmental samplesin aquatic environmental samples(surface seawater and sediments, settling particulate matters and aquatic organisms) were collected from Lake Shihwa in 2004. Due to extreme pollutant discharge from various kids of anthropogenic sources such as the Banweol and Shihwa Industrial Complexes and cities, the highest metal concentrations in the samples such as waters, sediments and settling particulate matter were found in inner part of the lake. Although the environmental qualities of heavy metals in the lake have been improved partially due to inflow of outer seawater, it is not clear to reach a good environmental quality. Therefore, further environmental programs should be conducted continuously for environmental improvement.
