| Abstract: | Based on systematic collection of the surface sediments of the Tuohe River in Suzhou City,the concentrations of heavy metals were measured by XRF.The results indicated that the concentrations of heavy metals in the Tuohe River are high as expressed by Pb,As,Cr,Cu and Zn,and their average concentrations are 40.8,14.6,58.8,52.2 and 143.3μg/g,respectively.The evaluation of pollution degree based on enrichment factor and geo-accumulation index showed that heavy metals of the sediments can be subdivided into three types: no-pollution(Cr),light-pollution(Pb and As),and moderate-pollution(Zn and Cu).Source discrimination of heavy metals by principle analysis indicated that As is controlled by the first factor,Cu and Zn are controlled by the second factor,and Pb is related to these two factors.In combination with other evidence,fossil fuel combustion(e.g.electricity generation) is considered to be the source of As and Pb,whereas the discharge of batteries and chemical materials,as well as agricultural activities,are related to the pollution of Zn and Cu,respectively. |
