title: Phytostabilization of metal contaminated soils.
abstract: The contamination of soils with heavy metals represents a worldwide environmental problem of great concern. Traditional methods for the remediation of metal contaminated soils are usually very expensive and frequently induce adverse effects on soil properties and biological activity. Consequently, biological methods of soil remediation like phytoremediation (the use of green plants to clean up contaminated sites) are currently receiving a great deal of attention. In particular, chemophytostabilization of metal contaminated soils (the use of metal tolerant plants together with different amendments like organic materials, liming agents, or phosphorus compounds and such) to reduce metal mobility and bioavailability in soils appears most promising for sites contaminated with high levels of several metals when phytoextraction is not a feasible option. During chemophytostabilization processes, one must at all times be cautious with a possible future reversal of soil metal immobilization, with concomitant adverse environmental consequences.
