However, with the use of phytoremediation, the possibility of safe selenium levels has never been closer. Cunningham, “phytoremediation of lead-contaminated soils: role of synthetic chelates in lead phytoextraction,” environmental science and technology, vol.

Interest in phytoremediation as a method to solve environmental contamination has been growing rapidly in recent years. Therefore, for sites that pose acute risks for human and other ecological receptors, phytoremediation may not be the remediation technique of choice [29, 46].
Figure 7 simplifies some advantages of phytoremediation 7: advantages of phytoremediation major advantages of the heavy metal adsorption technology by biomass are its effectiveness in reducing the concentration of heavy metal ions to very low levels and the use of inexpensive biosorbent materials . The wells provide an artery for tree roots to grow toward the water and form a root system in the capillary ining which plant to use:The majority of current research in the phytoremediation field revolves around determining which plant works most efficiently in a given application.

Title : phytoremediation of heavy metals laden waste water using duckweed species introduction presservation of the environment quality is one of the major concern of this century. If the daughter compounds are relatively benign, the plants can still be used in traditional most effective current phytoremediation sites in practice combine these three mechanisms to clean up a site.

Phytoremediation might be best suited for remote areas where human contact is limited or where soil contamination does not require an immediate response .
Cortez, “assessment and phytoremediation of heavy metals in the panlasian creek,” an unpublished high school thesis, university science high school, central luzon state university, science city of mu? On figure 1, some certain essential processes involved in phytoremediation technology [29, 31] are phytostabilization and phytoextraction for inorganic contaminants, and phytotransformation/phytodegradation, rhizofiltration, and rhizodegradation for organic root plants exudates to stabilize, demobilize and bind the contaminants in the soil matrix, thereby reducing their bioavailability.
This phytotoxicity could lead to a remedial approach in which high-concentration waste is handled with expensive ex situ techniques that quickly reduce acute risk, while in situ phytoremediation is used over a longer period of time to clean the high volumes of lower contaminant concentrations . A major limitation in the phytoremediation of toxic elements is the maximal level that can be accumulated by plants.
Phytoremediation can be an alternative to the much harsher remediation technologies of incineration, thermal vaporization, solvent washing, or other soil washing techniques, which essentially destroy the biological component of the soil and can drastically alter its chemical and physical characteristics as well as creating a relatively nonviable solid waste. Phytoremediation is regarded as a new approach for the cleanup of contaminated soils, water, and ambient air .
Limitations of phytoremediation technologyon the other hand, there are certain limitations to phytoremediation system (figure 8). Among them are being time-consuming method, the amount of produced biomass, the root depth, soil chemistry and the level of contamination, the age of plant, the contaminant concentration, the impacts of contaminated vegetation, and climatic 8: the limitation of phytoremediation emediation can be a time-consuming process, and it may take at least several growing seasons to clean up a site.

Table 2 lists some research done to remediate heavy metals from contaminated soil, while table 3 lists some research conducted to remediate them from contaminated water and 2: phytoremediation study on soil 3: phytoremediation study on water medium (hydroponic). Phytoremediation was used at the decommissioned detroit forge plant to clean up approximately 5,800 cubic yards of lead-impacted soil.
