| Abstract: | The characteristics of temporal and spatial distribution of heavy metals (Cu,Pb,Zn,Cd,Hg) in the surface sediment of Hailing Bay in western Guangdong Province have been analysed. National marine sediment quality for heavy metals were used to assess heavy metals pollution (degree) in Hailing Bay. The potential ecological risk (PER) factors and risk indices of heavy metals were used to assess the PER of heavy metals to marine ecosystem in water areas of Hailing bay. The result showed that the PER of heavy metals was low, and higher in dry season than in wet season, except the PER of Hg was relative higher. The heavy metals PER order is following: Zn
