Abstract
This study was carried out to understand the distribution and pollution history of heavy metals in sediments of Gohyun Bay, one of the semi-enclosed bays in Korea. In addition, to evaluate metal input loads and pathways in the bay which includes a large shipyard and city, river water and effluents were collected in several rivers and creeks. Highly elevated Cu and Zn contents were found in surface sediments near shipyard effluent outlet. Metal contents in the surface sediments steeply decreased towards of coast. At St. 2 and 6, heavy metal(Cu, Zn, Cd and Pb) contents slowly increased during the period of 1920-1970, rapidly increased during 1970-2000, and followed by slight decrease after 2000. The highest value of metal(Cu, Zn, Cd and Pb) excesses among the sediment cores were found at St. 2.
