Abstract

Surface sediment samples were collected from four sampling areas (Ganzhou nonferrous metal processing zones (GZ), Jian city sewage discharge areas (JA), Non city areas (NC) and Zhangshu middle-city areas (ZS)) to investigate the degree and chemical partitioning of heavy metals. Samples were analyzed for Cu, Zn, Pb, Cd, Cr, As and Ni using sequential extraction scheme. Based on geo-statistics analyses, the results showed maximum values of Cu (131.84 μg g-1), Zn (290.68 μg g-1), Cd (99.57 μg g-1), Cr (53.75 μg g-1), As (25.58 μg g-1) and Ni (64.75 μg g-1) were in sediments dated at GZ areas, while ZS areas had the highest concentrations of Pb (128.51 μg g-1). Almost all metal values were higher than their corresponding background values in the following order: Ni
