    Abstract:

    Twenty three soils and 8 vegetables around Wuhan Iron and Steel Corporation were collected and the contents of heavy metals Cu, Zn, Pb, Cr, Cd, Ni in these samples were investigated. Results showed that Cd content in all soils was higher than the background index of Hubei Province soil (BIHBS), indicating that there was serious soil Cd pollution. The average contents of Pb, Cr, Ni for all soils were below the BIHBS. Cu and Zn for most soils were medium or severe pollution. There were correlations between Cu, Zn, Pb, Cr, Cd, Ni contents and soil organic matter, and soil physical clay contents. When organic matter and physical clay contents were controlled, the cation exchange capacity and Cu, Zn contents showed significant partial correlation. Through Q type cluster analysis, soils from four sites were divided into 4 types based on the pollution degrees. Cluster I had the lowest pollution, which was consisted mainly with some samples from site 1 and site 4; Cluster IV had the severest pollution, which was consisted mainly with soils from site 2.
