영문 초록

This study was performed to characterize the seasonal fluctuation of sediment quality from January 26 to October 8, 1994 around northern port of Mokpo. Which is located in northern part of Mokpo harbour of Korea. The results are as follows: Ranges of ignition loss(IL) were 3.41~15.75%, and showed the highest mean value of 6.51% in surface sediment of spring season. Chemical oxygen demand(COD) concentrations showed the highest mean value of 9.90㎎/g-dry in surface sediment of spring season, while did the lowest mean value of 5.32㎎/g-dry in surface sediment of autumn season. Total sulfide(S) were in the range of ND~3.39㎎/g-dry, and showed the highest mean value of 1.22㎎/g-dry in surface sediment of summer season(June). COD and IL were higher at spring season, but S was higher at summer and autumn season(June). COD was lower than the standard of sediment quality, while S was higher than it in almost all area at summer and autumn season. Concentration ranges of cadmium and copper were ND~0.08㎎/㎏-wet, and 0.32~8.70㎎/㎏-wet., repectively. Those of lead and zinc were 0.97~10.45㎎/㎏-wet. and 5.55~27.84㎎/㎏-wet., respectively.
