영문 초록

We examined three factors to mainly cause the sedimentary contamination of Gamak Bay located at the southern coastal waters of Korea; one is an inflow of pollutant from the land, two is an inflow of pollutant from maricultural facilities of the bay, and three is a self-pollution by cultural shellfish itself. The result turned out that detritus of cultural organisms was the largest factor for sedimentary contamination, and then domestic and industrial sewage followed it. In addition, the pollution by maricultural facilities appeared to be a minor factor that does not directly affect the sedimentary contamination of the bay. Thus we could conclude that the sedimentary environment of Gamak Bay was contaminated by mainly a self-pollution by cultural shellfish and sewage from the land. On the other hand, the sedimentary contamination due to organic matters in Gamak Bay appeared to be more serious than before, and in particular, the northern part of the bay was likely to be more contaminated owing to sewage. Nevertheless, the sewage treatment plant that has started its operation in 2005 wass judged to have partly contributed to the mitigation of the sedimentary contamination in Gamak Bay.
