In this paper, the assignment coefficients and formation variable of five toxic elements (such as Pb, Hg, As, Cd and Cr) in soil have been determined. The variable regularity in soil has been discussed. A scientific reference has been provided in this paper. On the basis of this reference, we can infer five elements absorption mechanism, and prevent the deep-water and the crops from pollution.
本文测定了土壤中铅、汞、砷、镉、铬五种有毒元素的分配系数和形态变量，探讨了其在土壤中的变化规律，为科学推断这五种元素的吸收机理、防止深层水体及农作物受污染提供了参考依据。
