| Abstract: | Identification of the background content in environmental media from the concentration of the contaminant is a basic and important problem in the study of heavy metal pollution.There are no practice thinking clue and way to distinguish background content from the content of contaminant in the field of environmental science today.As a cese,Nanjing alloy factory was studied for its Cr background content in the soil polluted by Cr by means of Hazen probability gridding and the process how we carry the way through in practice is presented companioning with discussions in this paper.The results showed that Hazen probability gridding is useful in identifying the content of geological setting from contaminant.The parameters obtained from the means are significant for the explanation of the pollution situation in the study area. |
