... site owners and citizen groups are interested in phytoremediation as possibly the cleanest and cheapest technology that may be employed in the remediation of selected hazardous sites. Although current research continues to explore and push the boundaries of phytoremediation applications, there are certain limitations to plant-based remediation systems.  3, fiche 1, Anglais, - phytoremediation%20system

Another phytoremediation process is phytodecontamination. Definition: The contaminants can be degraded or removed from the soil matrix, through the process of rhizosphere degradation and phytoaccumulation/phytoextraction, respectively. These processes are different from phytostabilization, which only binds the contaminant and reduces its mobility.  2, fiche 3, Anglais, - phytodecontamination

Accumulator plants are known for many naturally-occurring chemical elements. The term "accumulator plant" is used here to describe plants which have dry-weight elemental concentrations greater than either the associated substrate or "normal" plants. Much work has centred on copper, zinc and selenium accumulators but little attempt has been made to explain the rationale of elemental accumulation. It is usually considered a "tolerance" mechanism, and only recently has the functional or essential role of these elements been suggested.  4, fiche 6, Anglais, - accumulator%20plant
