English

Subject field(s)
  • Biotechnology
  • Plant Biology
  • Anti-pollution Measures
DEF

[Process by which contaminants such as metals are] taken up by particular plants, which are then harvested to reduce contaminant concentrations in soil.

OBS

[There are] two versions of phytoextraction : natural hyperaccumulation, where plants naturally take up the contaminants in soil unassisted, and induced or assisted hyperaccumulation, in which a conditioning fluid containing a chelator or another agent is added to soil to increase metal solubility or mobilization so that the plants can absorb them more easily.

Key term(s)
  • phyto accumulation
  • phyto-accumulation

French

Domaine(s)
  • Biotechnologie
  • Biologie végétale
  • Mesures antipollution
DEF

Procédé utilisant les plantes accumulatrices de métaux lourds pour extraire, absorber, transporter et concentrer les métaux toxiques du sol dans les parties récoltables des racines et des parties aériennes.

OBS

On distingue [...] deux types de phytoextraction : la phytoextraction continue qui se fait naturellement et consiste souvent en une hyperaccumulation [et] la phytoextraction induite qui se fait en présence de chélateurs.

OBS

Les contaminants sont généralement éliminés lors de la récolte des plantes.

CONT

Phytoextraction is the use of plants to remove metals from soil, often while preserving the soil structure. Some plants have the specialized ability to remove large quantities of a specific metal from the soil, a process called natural hyperaccumulation.

OBS

[There are] two versions of phytoextraction : natural hyper-accumulation, where plants naturally take up the contaminants in soil unassisted, and induced or assisted hyper-accumulation, in which a conditioning fluid containing [an] agent is added to soil to increase metal solubility or mobilization so that the plants can absorb them more easily.

Key term(s)
  • natural hyper accumulation
  • natural hyper-accumulation

French

Domaine(s)
  • Biotechnologie
  • Biologie végétale
  • Mesures antipollution
CONT

Les plantes qui pratiquent la phytoextraction continue sont capables d'accumuler au sein même de leurs tissus des quantités importantes de polluants (et plus précisément de métaux lourds).

CONT

On distingue [...] deux types de phytoextraction : la phytoextraction continue qui se fait naturellement et consiste souvent en une hyperaccumulation [et] la phytoextraction induite qui se fait en présence de chélateurs.

[There are] two versions of phytoextraction : natural hyperaccumulation, where plants naturally take up the contaminants in soil unassisted, and induced or assisted hyperaccumulation, in which a conditioning fluid containing [an] agent is added to soil to increase metal solubility or mobilization so that the plants can absorb them more easily.

CONT

Phytoextraction is the use of plants to remove metals from soil, often while preserving the soil structure... there are currently no known natural hyperaccumulators for some metals such as lead. In order for plants to efficiently accumulate lead, a chemical called a chelating agent is required. This process is called induced hyperaccumulation.

Key term(s)
  • induced hyper accumulation
  • assisted hyper accumulation
  • induced hyper-accumulation
  • assisted hyper-accumulation
  • chemically enhanced phytoextraction
  • chemically assisted phytoextraction
  • chelate induced hyperaccumulation
  • chelate assisted phytoextraction

CONT

On distingue [...] deux types de phytoextraction : la phytoextraction continue qui se fait naturellement et consiste souvent en une hyperaccumulation [et] la phytoextraction induite qui se fait en présence de chélateurs.

OBS

[...] la phytoextraction induite comporte deux processus de base : [la] libération de métaux liés dans la solution du sol [et le] transport des métaux jusqu'aux parties récoltables.
