| 摘 要： | 对伊通河（长春市区段）沉积物中重金属元素的含量和形态的分布特征进行了研究。结果表明，重金属元素的总量呈现出沿河变化的趋势，且各重金属元素沿河变化程度有很大区别；沉积物中铁主要以残渣态存在，Mn、Pb、Cu、Zn元素残渣态含量很低，而有效态含量却很大（70%），即伊通河沉积物中存在着潜在的重金属污染。沉积物中重金属在各形态的叠加也有所区别，Pb和Cu主要叠加在有机物态和残渣态中，而Zn则主要叠加在铁锰氧化物态中。

| Abstract: | Distribution of heavy metals in the sediments from the Yitong River (Changchun section) was studied. It is indicated that amounts of heavy metals varied markedly along the river selected. Iron existed mainly in the form of residue, and most of other metals, including Mn, Pb, Cu, and Zn, existed in the form of available speciations (70%). The resulted information also showed that potential pollution of heavy metals are obvious in the sediments of the river, and Pb and Cu mainly accumulated in organic and residual forms with Zn in Fe and Mn oxides. |
