Summary:To investigate the sediment quality of Fudu Estuary waters in East Liaodong Bay, the grain size, concentrations of total organic carbon (TOC) and heavy metal (Cr, Cu, Zn, As, Cd, Pb) of 25 surface sediments were tested. The concentration of heavy metals was found to be higher in the Southwest of Yingkou Port and outside the Fudu Estuary. Cd is the principal contaminant with mild pollutant and moderate ecological risk. Cr may cause negative biological effects. The abnormal enrichment of Cu and TOC may respectively be caused by riverside industrial activities and mariculture. The abnormal enrichment of Pb in Moon Bay Beach and the Lagoon was suggested to be caused by the mooring of boats or excessive tourist activities. Grain size dominates the concentrations of heavy metals in the study area. The impact of coastal engineering on sediment quality through changing sedimentary dynamics should also be given particular attention.
