Abstract: Contents of heavy metals (Cu,Zn,Pb and Cd) in soils of grain area in the northwest of Shandong Province were investigated in order to evaluate environmental quality of heavy metals. The contamination status of above-mentioned soils was assessed by means of single and Nemerow Synthetical pollution index method comparing with the environmental quality standard for soils of China. The results showed that soils of grain area in the northwest of Shandong Province were low-grade polluted. The Nemerow Synthetical pollution index was 1.161.The single pollution indexes of Cu, Zn, Pb and Cd were not exceeded the quality standard, but the single pollution index of Cd was watchful.
