How does Rhizofiltration work?
Rhizofiltration refers to the use of plant roots to absorb, concentrate, and precipitate toxic metals from contaminated groundwater. Initially, suitable plants with stable root systems are supplied with contaminated water to acclimate the plants.
Which plant is used for Rhizofiltration?
A few examples of plants that are employed for rhizofiltration are sunflower, tobacco, spinach, rye and Indian mustard. Plant species besides hyperaccumulators can also be used, as the heavy metals need not be translocated to the shoots (Henry, 2000).
What is bioremediation PPT?
Bioremediation means to use a biological remedy to abate or clean up contamination. According to the EPA, bioremediation is a “treatment that uses naturally occurring organisms to break down hazardous substances into less toxic or non toxic substances”. Read more.

What is Phytovolatilization explain with example?
Plants can interact with a variety of organic compounds, and thereby affect the fate and transport of many environmental contaminants. Volatile organic compounds may be volatilized from stems or leaves (direct phytovolatilization) or from soil due to plant root activities (indirect phytovolatilization).
What is Rhizofiltration name few organisms associated with it?
Some of the most common plant species that have shown the ability to remove toxins from water via rhizofiltration: Sunflower. Indian Mustard. Tobacco. Rye.
What is Rhizofiltration in phytoremediation?
Rhizofiltration is a form of phytoremediation that involves filtering contaminated groundwater, surface water, and wastewater through a mass of roots to remove toxic substances or excess nutrients.
What are the types of bioremediation?
There are far more than nine types of bioremediation, but the following are the most common ways in which it is used.
- 5.1 Biopile.
- 5.2 Windrows.
- 5.3 Land farming.
- 5.4 Bioreactor.
- 5.5 Bioventing.
- 5.6 Bioslurping.
- 5.7 Biosparging.
- 5.8 Phytoremediation.
What is the meaning of Phytovolatilization?
Phytovolatilization. Phytovolatilization involves the uptake of contaminants by plant roots and its conversion to a gaseous state, and release into the atmosphere. This process is driven by the evapotranspiration of plants (Figure 3B).
How do Hyperaccumulators work?
A hyperaccumulator is a plant capable of growing in soil or water with very high concentrations of metals, absorbing these metals through their roots, and concentrating extremely high levels of metals in their tissues.

What are the basic principles of bioremediation?
The basic principle of bioremediation is hydrolysis of higher molecule contaminants into small and soluble entities which may undergo in the aerobic on anaerobic pathways.
