| 摘 要： | 在珠江口东侧航道附近的桂山岛周围7个位点采集表层沉积物样品,采用Hakanson生态危害指数法和污染系数初步考察了表层沉积物中重金属污染状况和生态危害程度,并由重金属富集因子分析了沉积物中重金属污染来源.结果表明,沉积物中Cu、Pb、Cd和Zn的富集达到中等污染水平,而Ni尚处于低污染水平;沉积物中重金属的生态危害目前... |

| Abstract: | The surface sediment samples were collected from 7 sites in Guishan island near the eastern waterway of the Pearl River Estuary,and the pollution degree and ecological risk of heavy metals in surface sediments were preliminarily investigated by Hakanson' risk index and pollution coefficient.The sources of heavy metals were studied by the enrichment factor.The results showed that the contents of Cu,Cd,Pb and Zn reached the moderate level polluted,however,the content of Ni was low.The ecological risk of heavy... |
