In this study,contents of seven trace elements along with Fe and Mn in the roadside soil near a trafficway of Huainan,Anhui province,China have been measured for the pollution assessment and source identification (along with quantification).The results show that iron is the most abundant element,followed by Mn,Zn,Cr,Pb,Cu,Ni,As and Co.They have coefficients of variation range between 0.038 and 0.622,indicating that some of them might have multi-sources.The single pollution and geo-accumulation indexes suggest that the soils are no-slightly to moderately polluted by different elements,and the Nemerow composite index suggests that 57.5%,35.0% and 7.5% are slightly,moderately and seriously polluted,respectively.Three sources responsible for the soil elemental concentrations have been identified by statistical analyses,the geogenic,agricultural and traffic related (and probably coal combustion) sources,and their mean contributions calculated by the Unmix model are 37.9%,32.0% and 30.1%,respectively.
