摘 要:渤海南部调查的区域包括渤海湾南部沿岸和莱州湾。调查区沉积物的物质主要来源是黄河。这个区域,特别是黄河河口,历史资料很少。近来,黄薇文作了黄河口的一些重金属在表层沉积物中的含量及其在各地球化学相中的含量,但未测定重金属在该区域的堆积通量。本文主要讨论渤海南部沉积物中铜和锌的分布及它们在二个站的堆积通量。Zinc and copper contents in sediment of southern Bohai Sea are higher. Partial correlation coefficients between Zn, Cu and Rb, Mdφ and organic matter are respectively:From the Partial correlation coefficients it can be concluded that the main fractions of zinc and copper in southern Bohai Sea sediment are contained in minerals, not contaminated.Accumulation rates of Zn and Cu at two stations were measured. The accumulation rates at station 14 (see table 2) have decreased greatly since 1976 when the course of Huanghe River changed to the east, but at station 20 have no obviously changed.
