摘要：

Heavy metal concentrations of the sediment from Tuohe river in Suzhou city, northern Anhui Province were determined, and the index of Geo-accumulation (Igeo) was calculated for evaluating the extent of the metal contamination. The principal components analysis (PCA) and correlation matrix(CM) have been used for the sources of heavy metal. The result showed: The degree of pollution arranged in the following decreasing order: Cu > Zn > As > Pb > Cr > V, V is unpolluted, Cr, Pb and As are light pollution, Cu and Zn are moderate pollution; Cu, V and Zn mainly originate from human activities, Pb and As mainly derived from the source rock, Cr mainly derived from clay minerals and colloidal material.
