Phytoremediation

Phytoremediation

• Plants acts a filters and metabolize substances generated by nature plants are used to remove contaminants from soil and water.

In phytoremediation four type of techniques:-

1. Phyto-extraction.
2. Phyto-transformation.
3. Phyto-stabilization.
4. Phyto-degradation.

1) Phyto-extraction:-

• In phyto-exraction contaminants are accumulated into the roots and above the ground shoots or leaves used for extracting heavy metals and phytomining.

2) Phyto-transformation:-

• In this phyto-transformation uptake of contaminants from soil, sediments or water take place.

3) Phyto-stabilization:-

•  In this phyto-stabilization plants reduce the mobility and migration of contaminants and contaminated soil.

4) Phyto-degradation:-

• Phyto-degradation is the breakdown of contaminants due to presence of proteins and enzymes produced by the plants.
