罗源湾海水中重金属的调查研究

Heavy Metal Survey and Study in the Luoyuan Bay Waters

为了开发利用罗源湾,我们于1986年11月至1987年9月调查了海水中重金属,报道了罗源湾海水中Cu,Pb,Zn,Cd,Hg②的含量及其分布特征,并着重研究了表层海水中Cu,Pb,Zn,Cd含量与盐度的关系。

The contents of Cu.Pb.Zn.Cd.Hg in the Luoyuan Bay waters were surveyed during Nov. 1986 to Sep. 1987. The determination of Cu.Pb.Zn.Cd were performed with GFAAS after a two-stage APDC-MIBK extraction procedure. The emphasis was put on the study of relationship between the contents of Cu,Pb,Zn.Cd and salinity in surface water. It has been suggested that the annual mean observed for the heavy metal were Cu 0.76±0.08 μg/l. Pb 0.058±0.024/μg/l, Zn 2.40±0.72μg/l. Cd 0.024±0.003μg/l, Hg 0.02μg/l. The concentrations of Cu.Pb,Zn.Cd are decreased gradually fromthe bay interior to the outlet.There is a better relationship between the contents and salinity.
