The representative parts, such as Jianhe Estuary, the Luannan Zuidong Industrial Zone, Caofeidian Industrial Zone, the Qinglonghe Estuary, Caofeidian Wetlands, the Laoting Qianshui Bay, and Jingtang Port in Bohai West Bank, were chosen, selecting the 13 sampling sites, 31 surface sediment samples. X-ray fluorescence spectrometry (XRF), atomic absorption spectrometry (AAS) and inductively coupled plasma mass spectrometry (ICP-MS) were used to test the samples of heavy metals concentrations. Studies have shown that except the Caofeidian Industrial Zone, Pb contents in the other sampling points are more than the background value. Zn exceeded in the two sampling sites and Ni in one sample point
