Abstract

To explore the status of heavy metals pollution in South China Sea, the surface samples of sixteen stations were collected. Concentrations of heavy metals Cu, Pb, Zn, Cd as well as relevant environmental parameters, such as TOC, pH value, salinity and so on, were analyzed. The Hakanson ecological risk index was adopted to assess the potential ecological risk of South China Sea. Concentrations of Cu (0.012~0.127mg/L), Pb(0.051~0.113mg/L), Zn(0.045~0.186mg/L) and Cd (0.047~0.324mg/L) in surface seawater were pretty high and the average level of them were beyond the third class of sea water quality standard of China. There was a significant correlation between four heavy metals and some of environmental parameters, which suggested their similar origins. Based on the potential ecological risk assessment results, the average RI value was 873.87, indicating a high ecological risk level. The descending order of ecological risk of heavy metal was Cd > Pb >Cu > Zn. Consequently, more efforts should be made to monitor heavy metal pollution and protect marine ecological environment.
