摘　　要：以毕节市内四个地区煤灰库的粉煤灰做研究对象,采用顺序提取重金属并测定重金属形态分布;建立ICP-AES法、ICP-MS法及AFS法分析Zn、Pb、Cd、Ni、Cr、Cu、Hg、As等重金属分布特征,运用潜在风险指数法评估八种重金属的潜在环境风险。In this paper,the heavy metals were extracted sequentially and the speciation distribution of heavy metals was determined from the fly ash from the coal ash storage and the thermal power plant in Bijie city.The distribution characteristics of Zn,Pb,Cd,Ni,Cr,Cu,Hg,As and other heavy metals were analyzed by ICP-AES,ICP-MS and AFS methods.The potential environmental risks of eight heavy metals were evaluated by potential risk index method.
