The Plant That’s Full Of Metal

Listen Later

To learn more about this topic, start your googling with these keywords:

  • Hyperaccumulator: a plant capable of growing in metalliferous soils and to accumulate extraordinarily high amounts of heavy metals, far in excess of the levels found in the majority of species, without suffering toxic effects
  • Phytoremediation: the treatment of pollutants or waste (as in contaminated soil or groundwater) by the use of green plants that remove, degrade, or stabilize the undesirable substances (such as toxic metals)
  • Phytomining: the planting (and subsequent harvesting) of vegetation that will selectively concentrate specific metals from the soil into their tissues
  • Euhalophytes: highly salt-tolerant plants capable of diluting salt within their succulent leaves or stems
  • Active transport: the process of transferring substances against a concentration gradient into, out of, and between cells, using energy
