Abstract

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

The content sequence of the four elements is Zn>Pb>Cd>Cu. Elements’ distribution characteristics in acid solution, iron and manganese oxides, organic state and residue state were analysed. More specifically Cu and Zn were mainly distributed in acid solution; the majority of Cd was in acid solution and iron and manganese oxides; but Pb was in acid solution, iron and manganese oxides and residue in general. [J].
