英文摘要	Based on the data of heavy metals (including total Hg, Cd, Pb, Zn, Cu, Cr and As) in 17 samples in the sediment of Lai Zhou Bay in the year of 2014, the distribution of heavy metals in the sea area and degree of sediment pollution were researched. With Hakanson's method, potential ecological risk of heavy metals in the sediment of Lai Zhou Bay was primarily assessed. The results demonstrated that the horizontal distribution of total Hg, As, Cd, Pb decreasing from center of Lai Zhou Bay to its west and south and the Yellow River Estuary. The horizontal distribution of Zn increased from northwest to southeast, Cu decreased from offshore to inshore, Cr decreased from inshore to the center of Lai Zhou Bay. Parameter of pollution metals on sediment was lower than 1, the value of RI was among 233.3 similar to 35.1, indicating that the degree of pollution of heavy metals on the sediment and its ecological risk were low. The pollutants in the order of impacting the extent of ecological risk were Cd>Hg>As>Cu>Pb>Cr>Zn.
