摘要
用1984年采集的福建龙海县滩涂区的样品,测定了沉积物及其酸可溶部分Fe,Mn,Cu,Zn,Pb,Co和Ni的含量,报道了它们的分布,分析了它们与Fe-Mn氧化物和有机质之间的相互关系,建立了相应的复相关式。
The distribution of Fe,Mn,Cu,Zn,Pb,Co and Ni in the sediments and acid-soluble fractions in the Longhai tidal flat and the relationship between elements in the sediments were analysed.It has been found that the heavy metals decrease seaward with high content in the north,and low content in the south.The contents of Pb and Zn in the sediments were higher thar those of normal sediments and they may derive from the north branch of Jiulong Jiang River.The contents of the trace metals in the sediments mainly controlled by Fe-Mn oxide and organic matter and their multiple relationships were statistically obtained.Mn and Pb mostly exist in the acid-soluble fraction and Fe,Cu,Zn,Ni and Co in acid-insoluble.A quasi-equilibrium in the sediments may Present between total metal content and its content in the various phases.
