Heavy Metal Pollution in Sediments of Nanwan Reservoir and Assessment of Its Potential Ecological Risk
测定了南湾水库沉积物中5种重金属元素(Hg、Cd、Pb、As、Cu)的含量,并根据Hakanson 潜在生态风险指数法对南湾水库沉积物中重金属污染元素导致的生态风险进行了分析.结果表明,各采样点Hg、As、Cd、Cu和Pb的含量范围分别为0.13～0.31 mg/kg、10.01～19.45 mg/kg、0.26～0.60 mg/kg、24.17～39.67 mg/kg和10.20～19.66 mg/kg.西双河和马家畈有中度Hg 污染；马家畈、…查看全部>>
This experiment measured the contents of typical heavy metal pollutants(Hg, Cd, Pb, As,Cu) and analyzed the potential ecological risks of heavy metal in the sediments of Nanwan reservoir using the index techniques of single factor and Hakanson ecological risk. The results showed that the contents of the five heavy metals were 0. 13 - 0. 31 mg/kg,10. 01 - 19. 45 mg/kg, 0.26 - 0. 60 mg/kg, 24. 17 - 39. 67 mg/kg and 10. 20 - 19. 66 mg/kg. There were moderate Hg…查看全部>>
