合肥市董铺水库沉积物重金属元素环境污染与潜在生态风险研究

The Environment Pollution and Potential Ecological Risk of Heavy Metal Element in Sediment from Dong-Pu Reservoir of Hefei

通过电感耦合等离子体质谱法(ICP-MS)对取自合肥董铺水库8个沉积物样品中Cu、Pb、Zn、Ni、Cr、Cd、As 7种重金属元素含量的测试,使用地质累积指数法与潜在生态风险评价模型对其环境污染与生态风险现状进行了研究,为合肥市的水源地保护提供了科学依据。

The contents of Cu,Pb,Zn,Ni,Cr,Cd and As from8sediment samples in Dong Pu reservoir from Hefei have been determined by Inductively Coupled Plasma Mass Spectrometry(ICP MS).The environment pollution and potential ecological risk have been studied by geo accumulation index and potential ecological risk evaluation model,and the study result can be used for the protection of water source in Hefei.
