What types of plants can be used for phytoremediation?
What is phytoremediation plants? Phytoremediation is a bioremediation process that uses various types of plants to remove, transfer, stabilize, and/or destroy contaminants in the soil and groundwater. In this process, the plant releases natural substances through its roots, supplying nutrients to microorganisms in the soil.
What is the fate of plants used in phytoremediation? Phytoremediation is a general term for several ways in which plants are used to remediate sites by removing pollutants from soil and water. Plants can degrade organic pollutants or contain and stabilize metal contaminants by acting as filters or traps.
What happens to the plant after phytoremediation? Plant residues obtained after phytoremediation can be converted into biochar. The generated biochar could be used as an effective sorbent for dye adsorption.
What types of plants can be used for phytoremediation? – Related Questions
Where can phytoremediation be used?
Phytoremediation uses plants to clean up contaminated environments. Plants can help clean up many types of contaminants including metals, pesticides, explosives, and oil. However, they work best where contaminant levels are low because high concentrations may limit plant growth and take too long to clean up.
What plants absorb heavy metals?
Brassica juncea (Indian mustard) and Eichhornia crassipes (water hyacinth) have the the highest tendency of absorbing heavy metals from soil and water, respectively.
Can all plants be used for phytoremediation?
Both terrestrial and aquatic plants can be used for rhizofiltration. For remediation of wetland water, aquatic species such as hyacinth, azolla, duckweed, cattail, and poplar are commonly used due to their high accumulation of heavy metals, high tolerance, or fast growth and high biomass production (Hooda, 2007).

How are plants used for bioremediation?
Plants use solar energy (through photosynthesis) to extract chemicals from the soil and to deposit them in the above-ground part of their bodies, or to convert them to a less toxic form.
These plants can then be harvested and treated, removing the pollutants.
What are the disadvantages of phytoremediation?
Limitations to phytoremediation in soil include:
The depth of the treatment zone is determined by plants used in phytoremediation.
High concentrations of hazardous materials can be toxic to plants.
It involves the same mass transfer limitations as other biotreatments.
It may be seasonal, depending on location.
What plants are Hyperaccumulators?
Hyperaccumulators are unusual plants that accumulate particular metals or metalloids in their living tissues to levels that may be hundreds or thousands of times greater than is normal for most plants (Reeves, 2003; van der Ent et al., 2013).
Is phytoremediation a viable form of rehabilitation?
It is one of the most natural and passive techniques available, and is often less expensive as a result. With rising energy and labor costs, it is being reconsidered as a viable treatment technique, especially in cases of strong public awareness.
How does phytoremediation improve soil health?
Rhizodegradation involves attenuation of organic contaminants into less toxic substances within the rhizosphere through biodegradation of soil microbes. This process is facilitated by root exudates (organic molecules) that sustain populations of soil microbes.
How do you increase phytoremediation?
To improve the bioavailability of heavy metals in contaminated soil, addition of chelating agents (e.
g.
Is phytoremediation good?
Phytoremediation has a great potential as a natural, solar energy–driven in situ strategy to treat soils and sites moderately polluted over large surfaces, provided the plants have been carefully chosen and the adequate agronomic methods are applied to manage correctly the phytoavailability of organic contaminants (

What is the difference between phytoremediation and Phytoextraction?
is that phytoremediation is (biochemistry) bioremediation by the use of plants while phytoextraction is a form of phytoremediation that exploits the process in which plants absorb substances, particularly heavy metals, from the environment and store them in their tissues.
Is phytoremediation in situ or ex situ?
Phytoremediation is the in situ use of plants and their associated microorganisms to degrade, contain or render harmless contaminants in soil or groundwater (Cunningham et al., 1996) (Figure 1.1).
What is the mechanism of phytoremediation?
Phytoremediation is a green emerging technology used to remove pollutants from environment components.
Mechanisms used to remediate soils contaminated by heavy metal are: phytoextrac-tion, phytostabilisation, phytovolatilization and rhizofiltration.
The two first mechanisms are the most reliable.
What is Phytotransformation process?
Phytotransformation is the ability of plants to change the molecular composition of certain chemicals.
In most cases, plants are able to create a non-toxic molecule from a toxic molecule.
This is another method in which an environment’s toxicity can decrease with the introduction of certain plant species.
