Abstract:Eight sediment cores collected with gravity corer and sediment profiles dug by handed-tools from the EBFZ marsh downstream of the Huolin River were studied with high-resolution distribut ion of heavy metal (Cu, Zn, Cr, Ni, Co, Pb, Fe, Mn), pH, TOC and TN.The results showed that Zn, Fe and Mn were inriched in the upper part of the sedimentary sequence and significantly correlated with TOC.On the contrary, heavy metal contents in most of the deeper layers of sediment cores were relatively lower and closed to geochemical background levels.Correlation between elements was easier to identify with high-resolution sampling.Heavy metal contents in the upper layers are higher in sediments that are closer to river and have high flooding frequency.
