| 摘 要： | 本文研究了锦州湾沉积物中重金属在不同粒级中的分布规律,据此得出了对沉积物重金属实测含量进行修正的粒度校正方法.经校正后,该湾沉积物中重金属含量较未校正者高3—40倍.对该地区≤2μm样品进行分相测定的结果表明,污染程度、沉积物化学组成均对重金属在沉积物中的相分布有影响,而重金属在不同粒级样品中的相分布无明显差异,在向人工海水-沉积物系统中投放各种污染物的模拟实验证明:金属向沉积物各相转移的动力学过程是迅速的,在一天内基本可达平衡.

| Abstract: | Three problems of heavy metal pollution in offshore sediment in Jingzhou Bay of the Bohai Sea were investigated in this work: (1) relation of concentration of zinc, cadmium, lead and copper with grain size of sediment; (2) partition of heavy metals between different geochemical phases in sediment, and (3) partition of heavy metals between different geochemical phases in the model of marin sediment, where flue dust, effluent, and suspended particles from the Huludao Zinc Smeltery situated close to the coast were introduced, respectively, into the marine water-sediment system. |
