摘　　要：对南方稀土矿山水系环境中Ｐｂ、Ｃｄ、Ｃｕ、Ｚｎ的化学形态进行研究，探讨４种重金属在此水系中的迁移转化规律。结果表明，ＮＨ＋４的存在容易引起ＣＵ、Ｚｎ、Ｃｄ再生污染，不利于Ｃｕ、Ｚｎ、Ｃｄ从水相向固相转化，而Ｐｂ受影响较小。The ecological effect and the transport of heavy metals in aquatic environment are closely related to their chemical species.This paper has studied and discussed the chemical species of Pb,Cd,Cu and Zn and their transport and transformation in aquatic environment.The results show that the existence of NH+4 is liable to cause the secondary pollution of Cu,Zn and Cd and affects their transport from water to h sedimenti but has less effection Pb pollution.
