| Abstract: | Based on the monitoring data of the heavy metals in September, 2009, the pollution status and the potential ecological risk of the heavy metals in Lanshan Port Temporary Ocean Dumping Site were studied by using the Hakanson ecological risk index, and the variation trend of ERI was analyzed. The results showed that the integrated contamination level and the potential ecological risk of the heavy metals were low in the surface sediments of Lanshan Port Temporary Ocean Dumping Site. The Cd and Hg were key factors of the potential ecological risk in dumping site. The variation trends of ERI showed the order of ecological risk degree was 2006>2009>2004>2008>2000, In 2009, it was higher than that of 2008, and the Cd and Hg had a larger increase. |
