摘要: 采用“三步连续萃取法”研究了哈尔滨市何家沟淤泥样品中重金属(Cu, Pb, Zn和Cd)的生物可利用性, 结合淤泥中重金属“可利用态”分析了重金属对环境影响的程度, 为淤泥的处理提供理论依据.

关键词: 淤泥, 重金属, 生物可利用性

Abstract: A three-step continuous extraction method was used to study the bioavailability of heavy metals including Cu, Pb, Zn and Cd in seven samples of sludges collected in Hejiagou River in Harbin. The impact of heavy metals on the environment is discussed based on the available metals, mobile plus mobilisable, in the sludge from Hejiagou, and the resulted information is expected to give a suggestion for the treatment of the sludge if discharged.

Key words: sludge, heavy metals, bioavailability
