Decontamination of Soils through Immobilization of Anthropogenic Organics by Biotic and Abiotic Catalysts

摘要：

Processes that cause immobilization of contaminants in soil are of great environmental importance because they may lead to a considerable reduction in the bioavailability of contaminants and may restrict their leaching into groundwater. Previous investigations demonstrated that pollutants can be bound to soil constituents by either physical or chemical interactions (Caiderbank, 1989). From an environmental point of view, chemical interactions are preferred, because they frequently lead to the formation of strong covalent bonds that are difficult to disrupt by microbial activity or chemical treatments. Humic substances resulting from lignin decomposition appear to be the major binding ligands involved in the incorporation of contaminants into the soil matrix through stable chemical linkages (Bollag et al., 1997; Gevao et al, 2000).
