The method employing statistical moments has been applied in to analyse and compare two models elaborated previously for a soil decontamination by sorption of pollutants on agglomerates. On the basis of the results obtained, the evaluation of significance of each transfer process has been proposed. From the comparison of the relationships between statistical moments (the first absolute moment and the second central one) and appropriate parameters of both models direct relationships between the parameters of these models have been found. The results obtained have been discussed in terms of a wide range of the operating parameters.
