| 摘 要： | 采用矿物学分析、BCR三步连续浸提、动态淋洗实验以及Hakanson潜在生态风险评价4种方法对锌浸出渣重金属的环境活性以及生态风险进行评价.结果表明,锌浸出渣中重金属的环境活性大小依次为Cd＞Zn＞Cu＞As＞Pb.废渣中主要重金属的潜在生态风险评价表明,该种废渣对环境具有很高的生态风险,单个重金属的生态危害顺序为Cd＞Zn＞Cu＞As＞Pb.Cd有很严重的生态风险,是对生态环境造成毒性的主要原因.

| Abstract: | Four different methods, namely mineralogical analysis, three-stage BCR sequential extraction procedure, dynamic leaching test and Hakanson Potential Ecological Risk Index Method were used to access the environmental activity and potential ecological risks of heavy metals in zinc leaching residue. The results demonstrate that the environmental activity of heavy metals declines in the following order: Cd>Zn>Cu>As>Pb. Potential ecological risk indices for single heavy metal are Cd>Zn>Cu>As>Pb. Cd has serious potential ecological risk to the ecological environment and contributes most to the potential toxicity response indices for various heavy metals in the residue. |
