Abstract—The research reveals the relationship and environmental conditions, such as reduction of pH in soil,
enrichment of heavy metals in soil of sewage irrigation area in change of redox conditions in soil, etc. Therefore, the
Guangdong province, southern China. Samples were collected research on the relationship and enrichment of heavy metals
from topsoil (0-10cm) and subsoil (30-40cm), and the total in soil is needed.
concentrations of heavy metals were extracted by HNO3–HF– Combining the methods of correlation and cluster
HClO4. It is concluded that Cu, Zn, Cd, and Pb may be analysis, the objectives of this study were: ⑴ to clarify the
homologous bined pollution, and Mn and Cr may be correlations of heavy metals (Cd, Cu, Zn, Pb, Mn, Ni, As, Cr
also homologous in soil. According to the result of cluster
and Se) in soil of sewage irrigation area in Guangdong
analysis, it is shown that Se and As may have the similar
environmental geochemical behavior in topsoil, because
