摘　　要：为探明付疃河中下游沉积物污染情况,对河底12个采样点表层沉积物中的TN,TP,OM和重金属(Cr,Ni,Cu,Zn,As,Cd,Pb)的含量开展调查,分析其分布特征、来源、污染水平以及健康风险。结果表明,城区段河流以及日照水库出库处TN,TP及OM相对较高,且相应的污染指数均为重度污染,其他区域为轻度~中度污染;除Pb外,其余6种重金属含量均高于东港区土壤背景值;城区段河流以及日照水库出口处重金属含量相对较高,可能受工业、农业及交通等复合因素影响导致;Cd处于轻度污染状态或中等生态危害状态,各类重金属均不存在非致癌健康风险,但存在可接受的致癌风险。In order to explore the pollution status in surface sediment of Futuan river.The content of total nitrogen,total phosphorus,organic matter and heavy metals(including Cu,Zn,Pb,Cd,Ni,Cr,Hg and As)in sediment of 12 samples were analyzed.The spatial distribution characteristics,pollution level and sources of pollutants were analyzed.The results indicated the total nitrogen single pollution index,total phosphorus single pollution index,comprehensive pollution index and organic pollution index of the urban river and the export of Rizhao Reservoir were generally seriously polluted while other sampling points were between light and moderate pollution.The average concentrations of other heavy metals were higher than the background value of Donggang district except for Pb.Heavy metal concentration of the urban river and the export of Rizhao Reservoir were generally higher than other areas.The sources of heavy metal pollutants may be caused by combined factors such as Industry,agriculture and transportation.The Cd content poses a mild to moderate risk.The heavy metals was no noncarcinogenic risk and carcinogenic risk levels were within the acceptable ranges.
