摘要
Based on systematic collection of the surface sediments of Tuohe River in Suzhou City, the concentrations of heavy metals were measured by XRF. The results indicated that the concentrations of heavy metals in Tuohe River are high. 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). In combination with other evidence, fossil fuel combustion 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.
