Assessment and Spatial distribution of zinc pollution in agricultural soils of Chaoyang, China

摘要：

　　In this paper,we collected 295 soil samples from Chaoyang as the experiment material,then identify the concentration and spatial distribution of zinc (Zn) in agricultural soils on the basis of The integrated pollution index (IPI) and index geoaccumulation (Igeo).The concentration of Zn in soils of Chaoyang are from 22.787 to 669.597 mg kg-1,with an average concentration of 107.082 mg·kg-1.And results of the evaluation show that the pollution excess rate is 2.03%,which indicated that most of samples are slightly polluted.Compared two evaluation methods,integrated pollution index focuses on the evaluation of pollution results,the Geo accumulation index method is more accurate and objective.
