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 [2]. Therefore, for sites that pose acute risks for human and other ecological receptors, phytoremediation may not be the remediation technique of choice [29, 46].
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). Mechanisms of heavy metal uptake by plantcontaminant uptake by plants and its mechanisms have been being explored by several researchers. Mine-land restoration: phytoremediation of heavy-metal contaminated sites—a critical view,” international ecological engineering society, :///ecoeng011/ecoeng011_.

The generic term “phytoremediation” consists of the greek prefix phyto (plant), attached to the latin root remedium (to correct or remove an evil) [28, 29]. For inorganics, mechanisms which can be involved are phytostabilization, rhizofiltration, phytoaccumulation and 1: uptake mechanisms on phytoremediation technology.
Phytoremediation is more than just planting and letting the foliage grow; the site must be engineered to prevent erosion and flooding and maximize pollutant uptake. Sigua, “phy toremediation potentials of selected tropical plants for ethidium bromide,” environmental science and pollution research, vol. After investigating using phytoremediation on a site contaminated with hydrocarbons, the alabama department of environmental management granted a site.
Garbisu, “phytoremediation: a technology using green plants to remove contaminants from polluted areas,” reviews on environmental health, vol. Currently, the majority of research is concentrated on determining the best plant for the job, quantifying the mechanisms by which the plants convert pollutants, and determining which contaminants are amenable to phytoremediation. Interest in phytoremediation as a method to solve environmental contamination has been growing rapidly in recent years.
Some definitions on phytoremediation that have been described by several researchers are listed in table 1: definition of lly, according to the above researchers, phytoremediation is defined as an emerging technology using selected plants to clean up the contaminated environment from hazardous contaminant to improve the environment quality. Phytoremediation research can also contribute to the improvement of poor soils such as those with high aluminum or salt levels [75]. 6) phytoremediation, the use of plant systems to remove toxic elements from the soil, has recently attracted a great deal of attention as an alternative means of soil decontamination, since it is a cost-effective, eco-friendl...
It is the most ecological cleanup technology for contaminated soils and is also known as a green r advantage of phytoremediation is the generation of a recyclable metal-rich plant residue [32]. At the naval air station joint reserve base fort worth, phytoremediation is being used to clean up trichloroethylene (tce) from a shallow, thin aerobic aquifer. Surface waters, and ground water worldwide, are increasingly affected by contaminations from industrial, research experiments, military, and agricultural activities either due to ignorance, lack of vision, carelessness, or high cost of waste disposal and treatment.
Phytoremediation as possibly the cleanest and cheapest technology can be employed in the remediation of selected hazardous sites [29]. On the collected data from the phytoremediation research listed in tables 2 and 3, the accumulation of heavy metals as, pb, and hg in plant tissue is summarized in respective, figures 4, 5, and 4: as accumulation in plant 5: pb accumulation in plant 6: hg accumulation in plant ing to figure 4, the highest accumulation of as in plant tissue (the researchers have not detailed which part it is, but it might be the whole plant) occurs in pteris vittata l. Macek, et al, “phytoremediation: biological cleaning of a polluted environment,” reviews on environmental health, vol.
At the iowa army ammunitions plant, phytoremediation is being used as a polishing treatment for explosive-contaminated soil and groundwater. Understanding mass balance analyses and the metabolic fate of pollutants in plants are the keys to proving the applicability of phytoremediation [46]. Phytoremediation was used at the decommissioned detroit forge plant to clean up approximately 5,800 cubic yards of lead-impacted soil.
Al research council (nrc), “lead in the human environment,” national academy of sciences, washington dc, 1980, p. 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. Even the phytoremediation technique seems to be one of the best alternative, it also has some limitations.
