Phytoremediation of Metal-Contaminated Soils D.A. Belluck, S.L. Benjamin, S. David (auth.), Jean-Louis Morel, Guillaume Echevarria, Nadezhda Goncharova (eds.) Phytoremediation, the use of plants to remediate environmental media, is being pursued as a new approach for the cleanup of contaminated soils and waters, including groundwater. Contamination of agricultural soil has been a worldwide concern, and phytoremediation is a promising alternative to conventional soil clean-up technology as a low cost and environment-friendly technology. However, the field application of phytoremediation is still limited, because of its low efficiency and long-period needed. In this paper, with discussion of the characteristics, mechanisms and.

Phytoremediation is an emerging technology helping to clean the soil and water bodies from noxious pollutants. Phytoremediation can provide a low-cost and sustainable way to improve the economies of developing countries. Phytoremediation is one of the most potent and viable solution for poor farmers through community-based management.

The clean-up of polluted soils and waters is very costly, and for many pollutants no feasible technologies are yet available. Plants possess highly efficient systems that acquire and concentrate nutrients as well as numerous metabolic activities, all of which are ultimately powered by photosynthesis.

Phytoremediation, an emerging cleanup technology for contaminated soils, groundwater, and wastewater that is both low-tech and low-cost, is defined as the engineered use of green plants (including. Phytoremediation potentially allows the inexpensive clean up of polluted environments.

These can be both aqueous and soil based, and pollutants can range from complex organic molecules to heavy metals such as lead, cadmium or zinc (Table 1) (Raskin et al., ).

Some applications rely. A study was designed to assess the phytoextraction potential of Glycine max L. for lead (Pb). Pots experiment was conducted. Viable seeds were planted in 5 kg of soil placed in each plastic pot having 0 ppm (control), 5 ppm, 10 ppm, 15 ppm, 20 ppm and 25 ppm of Pb respectively.

The study was carried out for a period of 12 weeks under natural conditions. A successful phytoremediation program, therefore, must take into consideration variations in soil properties of the specific site. Different approaches have been used or developed to mitigate/reclaim the heavy metal polluted soils and waters including the landfill/damping sites.

Phytoremediation i FOREWORD About GWRTAC The Ground-Water Remediation Technologies Analysis Center (GWRTAC) is a national environmental technology transfer center that provides information on the use of innovative technologies to clean-up contaminated groundwater.

Established inGWRTAC is operated by Concurrent Technologies Corporation. Environmental pollution affects the quality of pedosphere, hydrosphere, atmosphere, lithosphere and biosphere. Great efforts have been made in the last two decades to reduce pollution sources and remedy the polluted soil and water resources.

Phytoremediation, being more cost-effective and fewer side effects than physical and chemical approaches, has gained increasing popularity in.

Phytoremediation of Contaminated Soil and Water is the most thorough literary examination of the subject available today.

The successful implementation of phytoremediation depends on identifying plant material that is well adapted to specific toxic sites. Gentle remediation is then applied in situ, or at the contamination s: 1.

Phytoremediation can be a cost effective way to clean up contaminated soils, as at this Department of Energy test site (Photo courtesy Department of Energy Subsurface Contaminants Focus Area).

Phytoremediation is the use of green plants to remove pollutants from the environment or render them harmless. Current engineering-based technolo-gies used to clean up soils — like the removal of contaminated topsoil for storage in landfills — are very costly and dramatically disturb the landscape.

Phytoremediation is the use of plants to clean up a contamination from soils, sediments, and water. Phytoremediation takes the advantage of the unique and selective uptake capabilities of plant root systems, together with the translocation, bioaccumulation, and contaminant degradation abilities of the entire plant body for the remediation process.

The use of plants for the removal of heavy metals from soil and water offers a wide range of advantages. Phytoremediation is a technology which can be applied in situ without moving or excavating large amounts of contaminated soil and leaves.

Fig. Phytoremediation processes of contaminated soils Phytoremediation processes rely on the ability of plants to take up and/or metabolize pollutants to less toxic substances.

The uptake, accumulation and degradation of contaminants vary from plant to plant. The plants used in phytoremediation. In recent decades, severe contamination of soils by heavy metals has been reported. It is, therefore, a matter of urgency to develop a new and effective technology for removing contaminants from soil.

The environmentally friendly solution to these problems is phytoremediation. Phytoremediation literally translates as „restoring balance. phytoremediation technologies to clean up shallow groundwater.

This report was prepared by a graduate student from Duke University during the summer of It has been reproduced to help provide federal and state project managers responsible for hazardous waste sites with information on the current status of this technology.

Phytoremediation is the use of plants and its associated microorganisms to achieve the conditions necessary to facilitate the breakdown of contaminants and clean-up of the polluted environment.

Phytoremediation technology is viewed as the simplest way of handling variety of contaminants in many sectors of oil industry. in an economic evaluation of the use of phytoremediation combined with energy crop production for the remedia-tion of sites diffusely polluted with heavy metals.

This is necessary because the feasibility of the long-term strategy of phytoremediation has to be tested against the current remediation techniques. polluted sites recently had primarily driving force behind the search to develop new alternative technology, which is called phytoremediation.

Despites of its feasibility and great potential as a viable approach in cleanup polluted environment, phytoremediation is yet.

Phytoremediation as a Cleansing Tool. An Overview Phytoremediation is described as a natural process car-ried out by plants and trees in the cleaning up and stabi-lization of contaminated soils and ground water.

It is actually a generic term for several ways in which plants can be used for these purposes. @article{osti_, title = {Phytoremediation of soils and water contaminated with toxic elements and radionuclides}, author = {Cornish, J E and Huddleston, G J and Levine, R S}, abstractNote = {At many U.S.

Department of Energy (DOE) facilities and other sites, large volumes of soils, sediments and waters are contaminated with heavy metals and/or radionuclides, often at only a relatively. Several plants have also been described to have phytoremediation potentials to clean up petroleum polluted soils (Frick et al., ; Njoku, ; Njoku et al ).

The efficacy of plants to remediate petroleum polluted soils depends amongst other factors on the nutrient availability in such soil.

Such plants can be used to clean up heavy metal contaminated sites. Wil-low (Salix viminalis L.), maize (Zea mays L.), Indian mustard (Brassica junceaL.), and sunflower (Helianthus annuus L.) has been found to be highly tolerant.

Any means to reduce heavy metal pollution in the environment is of considerable economic significance. The use of green plants to clean up heavy metal pollution is an environmentally friendly as well as a low-cost approach to the problem.

This plant-based biotechnology is commonly known as ‘phytoremediation’. Phytoremediation: Using Plants To Clean Up Soils The lack of vegetation in the barren area above is a result of the soil's high zinc content and low pH. This site in Palmerton, Pennyslvania, was contaminated by a zinc smeltry operated from to (K) "Contaminated soils and waters pose major environmental, agricultural.Phytoremediation represents an efficient ecological solution for treating the polluted soils through the use of plants.

This is a passive process, with low costs, appropriate for the limitation of the risk of hazardous wastes in the case of in-depth contaminated soil. This paper presents a research with a novel result on soil remediation.Forum—Using Superplants To Clean Up Our Environment Phytoremediation is an innovative use of green plants to clean up our environment.

The term comes from the Greek word for plants ("phyto-") that can detoxify, or remediate, soil or water contaminated with heavy metals or excess minerals.
