%X The content and distribution of heavy metals (Pb, Cd, Cu, Zn) in the surface sediment samples collected from the shellfish culture area of Zhangzi Island, were analysed. Their potential ecological risks were assessed with the method presented by Lars Hakanson. The results showed that the contents of Pb, Cd, Cu and Zn were higher in winter and lower in summer, and the highest content is 9.17±2.05, 0.06±0.014, 6.71±2.01 and 24.94±5.21 mg/kg respectively, which is far lower than that in other areas and also the national criterion. Therefore, there was no potential economical risk of the heavy metals in this area and the environmental quality of culture was very well.
