香港维多利亚港沉积物Cu、Pb、Cd在各地球化学相中的分布特征

The Characteristics of Gechemistry of Cu,Cd and Pb in Sudrface Sediment of Victoria Harbour

测定了香港维多利亚港沉积物中Ｃｕ、Ｐｂ和Ｃｄ三个元素的五种地球化学相，并初步探讨了它们的各形态分布规律．为研究重金属在沉积物中的存留及迁移规律、地球化学过程，以及污染源的调查研究等提供科学依据．

surface sediments of victoria harbour on Hong Kong have been ana-lyzed for trace metals after sediment fractions(exchangeable,carbonate,reducible,organic/sulphidic and residual fraction )are sequentially leached.Trace concentrations of Cu,Cd andPb are determined by ICP-AES.The distribution patterns and relationship of the investigatedelenients are discussed.The results show that the distribution of sediment fractions are con-trolled by the organic material in sediment and seawater. The major fraction of the heavymetals is non-residual.Organic/sulphidic form is the most important one.
