摘      要：Introduction:The development of coal power base(CPB)poses a severe challenge to the *** conducted a soil survey in Xilinhot CPB,to evaluate and analyze the pollution characteristics,potential ecological risk,and sources of six heavy metals(As,Pb,Cu,Zn,Mn,and Cd)in soil by using Geo-accumulation index,revised Nemerow integrated pollution index(RNIPI),and potential ecological risk index(RI).Outcomes/other:The results showed that the pollution of Cd and As were *** mean of Cd and As were 1.11 mg·kg^(-1) and 25.13 mg·kg^(-1),which were 42.55 times and 4.41 times higher than its local background *** Geo-accumulation indices showed the contamination degree of Cd was strong and As was moderate,and the status of Cu,Pb,Zn,and Mn were *** was strongly contaminated based on its RNIPI and RI ***:The accumulations of As,Pb,and Cd were mainly associated with anthropogenic sources,including coal mining and combustion,and industrial exhaust ***,Mn,and Zn were primarily originated from the parent material(natural sources).Conclusion:This study provides scientific basis and effective countermeasures for the prevention and control of soil pollution in surrounding areas of CPB.
