[The variable regularity of five toxic elements].
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.
