21 Sedimentary samples were taken from the rivers in north part of Anhui province, China. The contents of 8 heavy metal elements (Be, Cd, Cr, Cu, Pb, Ni, Mn, and Zn) were determined by ICP-MS. Organic matter contents in sediment were also tested. The results show that the different degree enrichments of heavy metals in sediments are appearing as compared with the average values of heavy metal contents in soils in China. Moreover, organic matter concentrations are decreasing progressively from upper reaches to lower reaches in the major river. The distribution features of Be, Cr, Mn, and Zn in sediments are more clear in research area as compared with the others. The pollution of heavy metals was comparatively light in sediments from the rivers in north part of Anhui, and only two heavy metals (Cd and Mn) existed contaminating in some rivers.
