Analysis of Harm Caused by Heavy-metal Pollution in Soil of Liaocheng
Take the 40 samples collected from farmland soil for testing.Use the single-factor variance analysis and multiple linear regression method to analyze the potential influence on ecological risk factor caused by heavy metal pollution by physical and chemical properties of soil.The results demonstrate that the potential ecological risk factor of a single metal is:Cd ＞ Hg ＞ As,Pb,Cu ＞ Cr,Zn;Organic matter has a promotion effect on potential ecological risk of metals in the physical and chemical properties of soil.The pH value takes on the antagonistic effect.The prevention and control of heavy metal pollution of soil in Liaocheng should be based on Cd and Hg.Take measures to reduce pollution to keep the pH in alkaline environment.
