Abstract

The analysis of soil heavy metals in Zhengzhou suburb of Henan province showed that the integrated pollution index was 1.9,which was in the state of light pollution.The main pollutant was Cd,and the average single-factor pollution index was 2.44.With the extension of cultivation,the soil heavy metals showed the characteristics of surface accumulation in the profile distribution.The correlation coefficient among Ni,Cu,and Pb was high,which could be associated with the same source.
