| Abstract: | According to the study of heavy metal elements in surface sediments of mangrove wetlands in Northern Hain- an Island, it found that the level of Cu, As, Zn, Ni and Cr element in the surface sediments of Dongzhai Harbor, Qinglan Harbor and Xinying Harbor were all higher than the soil background value of Hainan. The correlation analysis, factor analysis and cluster analysis showed that heavy metal elements Cr, Cu, Ni and Zn had significant correlations with each other, which indicated that the heavy metal elements have the same or similar material sources. |
