Considering the environment behaviors of contaminant in soil
such as diffusion
equilibrium/nonequilibrium two-site absorption-desorption and microbiological degradation
the kinetic model of the contaminants transport in soil is established; and its finite difference equation is given. Based on it
the distribution regularities of the contaminant concentration in soil are discussed in detail; and the sensitivities of parameters and are analyzed. The study shows that the parameter has important influence on the concentration distribution in soil and the influence degree is also related to the proportion (1- ) of nonequilibrium sites to total sites; At the later stage of pollution
the existence of absorption phase may increases the solute concentration in the water in soil; and the lager is
