An innovative approach to the modelling of distribution of volatile organic contaminants in the system soil dry matter - soil water - soil air is presented. An extended sorption coefficient is introduced comprising specific sorption on silicon- and aluminium-based soil constituents. The model was verified experimentally by the laboratory-scale simulation of tetrachloroethene sorption. The contaminated model samples were analyzed. The resulting distribution model confirmed the validity and practical importance of the extended soil sorption coefficient, which can be easily obtained by elemental analysis of the soil.
