| 摘 要： | 为评价污水灌溉区农田土壤重金属污染状况,采用单因子指数和综合多因子指数法,对沈阳西郊污灌区农田土壤重金属铜锌铅的污染特征进行了研究.结果表明,于洪区宁官、高明、胡孤家和四台子四个样点土壤均受到三种重金属污染,其中宁官点0～10 cm土层铜、锌、铅含量分别达到69.74 mg·kg-1、275.09 mg·kg-1和81.83mg·kg-1,分别足当地土壤背景值的2.82、4.59和3.60倍.各样点土壤有效态铜、锌、铅含量也远高于未受污染地区的平均含量,土壤铜、锌、铅有效态含量占全量的比例分别为4.65%～15.46%、1.36%～3.84%和5.46%～18.86%.说明沈阳西郊污灌区农田土壤重金属污染较严重,必须通过工程、生物及化学措施进行长期的污染治理.

| Abstract: | The farmland soils in western Shenyang suburb,Liaoning Province of China were irrigated with waste waster in late of the last century.To assess heavy metal contamination status in soils irrigated with waste water,the characteristics of Cu,Zn and Pb pollution in farmland soils of western Shenyang suburb were evaluated using single-factor indices and multiply-factor indices.The results show that all the test soils in Ningguan,Gaoming,Hugujia and Sitaizi were contaminated by Cu,Zn and Pb.Total content of Cu,Zn... |
