%X By selected three small towns,we studied the pollution character of heavy metals in sediments.Results show that the content of sediments-Zn is between 3.11 g/kg and 3.74g/kg,which is heavily excess the criterion of farming fertilized by sullage.The Zn-pollution of sediments has been a territorial and heavily pollution question of small towns,the content of sediments-Pb is between 0.03 g/kg and 1.00g/kg,And that of sediments-Cu is between 0.07g/kg and 0.20g/kg.The river sediments has also been polluted by Pb and Cu.To the diversity-region,light-toxicity metals(Fe,Mn,Zn) is less than heavy-toxicity metals(Pb,Cu,Cr).The river sediments from small towns can not be fertilized to the farmlands. By analyzed the relativity of TP-metals(Fe,Cr,Cu,Mn,Pb,Zn) and that of Fe-metals(Fe,Cr,Cu,Mn,Pb,Zn),we can conclude living sewage form small towns is a source of metals in sediments.Street-dust is an important source of sediments-Pb through surface-eroded by living-sewage.
