Phytoremediation

 
4.4 Phytoremediation
 
Definition of Phytoremediation
One of the treatment methods which uses plants for the purpose of degradation, extraction or elimination of pollute substances from soil and water.
 
Phytoremediation Method
  • Phytoremediation method is one of the alternatives in waste water treatment by eliminating heavy metals and also trapping harmful nutrients and microorganisms.
  • Phytoremediation treatment uses aquatic plants that can absorb heavy metals and nutrients contained in waste water.
  • The examples of plants used for phytoremediation is:
    • Eichhornia crassipes (water hyacinth).
      • This plant has long roots which can accumulate heavy metals such as copper and lead in water.
 
The image is an infographic titled ‘USES OF AQUATIC PLANTS IN PHYTOREMEDIATION’ with the logo ‘Pandai’ on the top right. It features four orange boxes with white numbers and text, each describing a different aquatic plant used in phytoremediation: 1. Water hyacinth 2. Sunflower 3. Water lettuce 4. Water spinach Each box is connected by arrows pointing to the next, indicating a sequence.
 
Uses of Aquatic Plants in Phytoremediation
Example of Plants Function
Water hyacinth
  • This plant has long roots which can accumulate heavy metals such as copper and lead in water.
Sunflower
  • Sunflower acts as a hyperaccumulator which can eliminate heavy metals such as zinc, chromium, copper, lead and nickel and also radioactive substances such as caesium and strontium.
Water lettuce
  • To treat waste water by accumulating heavy metals and absorb nutrients in the waste plant.
  • Has a fast growth rate.
Water spinach
  • The roots of ground water spinach are able to absorb mercury from the soil whereas the roots of river water spinach are able to absorb heavy metals such as cadmium from the water.
