  • 摘要: 研究了太湖流域漕桥河沉积物的重金属含量特征,结果显示,漕桥河沉积物的Cu、Pb、Zn、Ni、Cd的平均含量分别为46.5、40.6、149.9、58.7、0.54 mg·kg-1,不同的重金属之间存在显著相关关系(PP<0.05).沉积物中的不同重金属均呈现富集的趋势.生物毒性效应评价显示,Ni是可能造成生物负面影响的主要因子,其次是Cu、Zn;ERMQ评价说明漕桥河部分区域的沉积物已经存在生物毒性的风险.
    Abstract: Heavy metal distribution characteristics of Caoqiao River, Taihu Basin were studied in this paper. The results showed that mean values of Cu,Pb,Zn,Ni,Cd in sediment were 46.5, 40.6, 149.9, 58.7 and 0.54 mg穔g-1, respectively. Significant correlation was observed among the tested metals (PP<0.05). Heavy metals were found to be enriched in sediment of Caoqiao River compared to the baseline level. Evaluation of biological toxicity effects showed Ni was the main element which caused potential negative biological impact, followed by Cu and Zn. Results of an ERMQ assessment indicated that biological toxicity risk was found to exist in some of the sample sites.
