摘    要:研究了海沧周边海域表层沉积物为7种重金属(Fe、Mn、Cu、PbZn、Co、Zi)的含量,讨论了它们的分布趋势、相互关系和主要来源,结果表明,该海域表层沉积物中重金属的分布比较均匀,Pb、Zn、Co含量较高,Cu、Ni含量偏低,微量金属含量不受Fe-Mn氧化物控制,重金属主要来源于陆源风化产物和沿海散布的小型金属矿床,具有福建沿海口港湾沉积物普遍存在的地球化学特征。

关 键 词:厦门海沧  表层沉积物  重金属  地球化学特征  海洋监测

Abstract:The contents of 7 heavy metals (Fe、Mn、Cu、Pb、Zn、Co、Ni) in surface sediments are studied and their distribution, interrelation and main resources are discussed along the coast surrounding Haicang Economic Development Zone, Xiamen. The results show that contents of heavy metals are well-distributed in the surface of sediments, and Pb、Zn、Co are higher than those of Cu、Ni, and the contents of trace metals are not controlled by the Fe-Mn oxides. The main resources of heavy metals are from terrestrial weathering products and minitype metal beds. Those take on the ubiquitous geochemical characteristics of the sediments in the rivermouths and bays distributing along the coast areas in Fujian province.
Keywords:Haicang  surface sediments  heavy metal  geochemical characteristic
