| Abstract: | Based on the investigation of the heavy metals in surface sediment in 2009 in Xiaoyao Bay,the assessesment on the potential ecological risk degree by Hakanson ecological risk index was made.The results showed that the integrated contamination level of the heavy metals and the potential ecological risk of the heavy metal were low in sediments,and the heavy mental potential ecological risk,and the cadmium and mercury are key factors of the potential ecological risk in the survey locations. |
