| 摘 要： | 以北方某河流河床及河流两侧农田中土壤为研究对象，采用地累积指数法和潜在生态危害指数法对土壤中Cd 和Ni 的污染状况进行风险评价。结果表明，废弃冶炼中心处河床及河流两侧土壤中 Cd 和Ni 污染严重，均超过当地土壤背景值; 河床中土壤重金属富集程度为Cd ＞ Ni，其中Cd 富集程度达5 级，为重污染。以当地土壤背景值作为参比值进行评价，该河流处于重度的潜在生态危害程度，重金属的生态危害顺序为Cd ＞ Ni。

| Abstract: | For investigation of the risk assessment of Cd and Ni pollution in soil,the authors used geo-accumulation index and potential ecological risk index methods,taking the soils in riverbed and farmland of one river in North China as an example.The results showed that the soils from riverbed and farmland near waste smelting center were severely polluted by Cd and Ni,which were higher than the local background soil value.The enrichment degree of heavy metals in riverbed was Cd>Ni,and the Cd reached grade 5(heavy ... |
