Abstract

Phytoremediation is an emerging technology that uses plants and their associated microorganisms to depollute soils, air, sediments and waters. This phytotechnology is based on the capacity of some plant species to tolerate, absorb, accumulate and degrade pollutants. The ultimate goal of a phytoremediation process must be not only to remove the contaminant from the polluted soil but to restore soil quality, i.e. its capacity to function sustainably. Biological indicators of soil quality, especially those related to the biomass, activity and biodiversity of soil microbial communities, have great potential as monitoring tools for the assessment of the efficiency of a phytoremediation process. These bioindicators are particularly useful for the assessment of the effect of metal phytoextraction processes on soil quality.
