黄河口输出的泥沙对渤海沉积物。特别是对渤海西南部沉积作用产生极大影响。为了判断近期沉积物中某些重金属含量有无异常,或是否受到污染,有必要对该区表层沉积物中重金属的地球化学过程进行研究。本文讨论了该区表层沉积物中铜、锌、铁、锰有机质等含量及分布变化规律。
Sediment output from the Yellow River Estuary to the Bohai Sea sediments. Especially for sedimentation in the southwestern Bohai Sea. In order to determine whether some heavy metals in the sediments are abnormal or contaminated, it is necessary to study the geochemical processes of heavy metals in surface sediments. This paper discussed the content and distribution of organic matter, such as copper, zinc, iron and manganese in surface sediments of this area.
