The usefulness of humus fractionation methods in studies about the behaviour of pollutants in soils

Humus organic and organo‐mineral components prevail in the retention and movement of most pollutants in soils. Numerous kinds of physical, chemical, sometimes unknown bindings, are involved, especially in the fixation of pesticides residues. Fractionation methods attempt to improve knowledge about the relation between the distribution of pollutants and the nature of native compounds in soils.
