황해 중앙부해역 표층퇴적물내 금속원소의 분포특성 = Characteristics of Metallic Elements Distribution in Surface Sediments of the Central Yellow Sea

다국어 초록 (Multilingual Abstract)

Thirteen surface sediment samples collected from the central area of the Yellow Sea, were analyzed for their contents of thirteen metallic elements, including Al, Fe, Ca, Mg, K, Na, Cu, Cr, Ni, Pb, Co, Zn and Mn, as well as their grain-size and organic carbon content.
The sandy sediment facies are distributed in the eastern area, the sandy mud and clay sedimentary facies are distributed in the central region, and a patch of fine-grained mud is exists in the western central part. The content of organic carbon which ranges from 0.3 to 1.3% in the sediment showed increase with the decrease of grain-size, and that is dominantly high concentration in the western mud patch region.
The total concentration of A1, Fe, Ca, and Mn are higher in the northwestern part near toward the Shandong Peninsula and its decreased the eastern and southeastern part far away from the Huanghe River. This distribution patterns are well coincide with grain-size. The elements content such as Cu, Ni, and Cr are enriches in the southwestern mud patch region and it seems to be partly influence by the Changjiang Diluted Plume.
