Phytoextraction of metals from a multiply contaminated soil by Indian mustard.
TLDR
A significant enhancement of metal uptake was observed in NTA-treated plants for Cu and Zn, and Indian mustard shoot dry weights suffered significant reductions following NTA application.About:

Phytoremediation Technology: Hyper-accumulation Metals in Plants
TL;DR: A review of the application of phytoremediation in alleviating heavy metal toxicity is presented in this article highlighting the relative merits of different options and revealing a cutting edge application of emerging strategies and technologies to problems of heavy metals in soil.
Journal ArticleDOI
Field crops for phytoremediation of metal-contaminated land. A review
TL;DR: The phytoremediation efficiency of field crops is rarely high, but their greater growth potential compared with hyperaccumulators should be considered positively, in that they can establish a dense green canopy in polluted soil, improving the landscape and reducing the mobility of pollutants through water, wind erosion and water percolation.
Journal ArticleDOI
Characterization of heavy metal-resistant endophytic bacteria from rape (Brassica napus) roots and their potential in promoting the growth and lead accumulation of rape.
TL;DR: Two lead (Pb)-resistant endophytic bacteria were isolated from rape roots grown in heavy metal-contaminated soils and characterized and could colonize the root interior and rhizosphere soil of rape after root inoculation.
Journal ArticleDOI
Remediation of Heavy Metal Contaminated Soils: Phytoremediation as a Potentially Promising Clean-Up Technology
TL;DR: To enhance phytoremediation as a viable strategy, microbiota from the rhizosphere can play an important role, but the use of genetic engineering can also increase the success of the technique.
Journal ArticleDOI
Isolation and characterization of a heavy metal-resistant Burkholderia sp. from heavy metal-contaminated paddy field soil and its potential in promoting plant growth and heavy metal accumulation in metal-polluted soil.
TL;DR: Results show that heavy metal-solubilizing and plant growth promoting bacteria are important for plant growth and heavy metal uptake which may provide a new microbial enhanced-phytoremediation of metal-polluted soils.

Phytoremediation: A Novel Strategy for the Removal of Toxic Metals from the Environment Using Plants
David E. Salt,Michael J. Blaylock,Nanda P. B. A. Kumar,Viatcheslav. Dushenkov,Burt D. Ensley,Ilan Chet,Ilya Raskin +6 more
TL;DR: Biological mechanisms of toxic metal uptake, translocation and resistance as well as strategies for improving phytoremediation are also discussed.
Journal ArticleDOI
Molecular mechanisms of plant metal tolerance and homeostasis.
TL;DR: Recent progress in the molecular understanding of plant metal homeostasis and tolerance is reviewed and a number of uptake transporters have been cloned as well as candidates for the vacuolar sequestration of metals are identified.

Enhanced Accumulation of Pb in Indian Mustard by Soil-Applied Chelating Agents
Michael J. Blaylock,David E. Salt,Slavik Dushenkov,Olga Zakharova,Christopher D. Gussman,Yoram Kapulnik,Burt D. Ensley,Ilya Raskin +7 more
TL;DR: In this paper, Indian mustard (Brassica juncea) was used to demonstrate the capability of plants to accumulate high tissue concentrations of Pb when grown in Pb-contaminated soil.
Journal ArticleDOI
The possibility of in situ heavy metal decontamination of polluted soils using crops of metal-accumulating plants
TL;DR: In this article, the use of metal-accumulating plants is explored for the removal of metals from superficially-contaminated soils such as those resulting from the long-term application to land of metal contaminated sewage sludges.
Journal ArticleDOI
Chelant extraction of heavy metals from contaminated soils.
TL;DR: The results indicate that the J-Field contaminated soils can be successfully treated using a soil washing technique, and EDTA and citric acid appear to offer the greatest potential as chelating agents to use in soil washing the Aberdeen Proving Ground soils.
