Abstract: Distribution of the content of heavy metals in marine sediment in Sansha Bay was analyzed according to the investigation data in 2004, its ecological harm was evaluated with the index method of potential ecological harm. The result showed that the ecological harm of heavy metals was slightly,except the serious pollution of Hg and Cd.Investigation on microelement in surface sediment in Sansha Bay was conducted, too.
Comparison of these results with those from other sea area at home and abroad was made in this paper. The mean values of microelement Fe2O3, Ni and Mn in surface sediment from Sansha Bay were higher than that from continental shelf of northern south china sea, of which the major factor was that metal ores was eroded by rainstorm and variety of microelements was carried into marine surface sediment by river runoff.
In addition, Al2O3 had significant correlation with Fe2O3. The correlation between Al2O3 and Co, Al2O3 and Ni were also significant, showing distinctive geochemistry.
