| Abstract: | The situation of soil contamination with heavy metals in agricultural soil in the northern suburb of Xuzhou City was studied.The results indicate that the average contents of heavy metals(Cu,Cd,Pb,Zn,Cr) in the soil exceed the(background) values.The soil has been seriously contaminated with Cd and(Cr.) Pollution of Zn is at the warning-grade,(while) others are at the safe-grade. The order of integrated contamination index is Cr>Cd>Zn>Cu>Pb. |
