Hydrologic evaluation of a poplar phytoextraction system
International Journal of Phytoremediation, 2021This paper reports the results of a seven-year study of a phytoremediation system consisting of 349 hybrid poplars (Populous deltoids x Populus nigra 'DN-21') that were emplaced to reduce the migration of impacted groundwater toward a nearby stream. For the relatively small tree stand, the achievement of hydraulic containment was challenged by several ...

Biodegradable Chelant-Assisted Phytoextraction
2018The present manuscript reviews the research progresses on the phytoextraction of metals using biodegradable chelants in our research group. It mainly focuses on the theoretical considerations including metal solubilization, root uptake and translocation upward to the shoots, the effects of chelant application on metal leaching and soil microbes, and ...

Use of Willow in Phytoextraction
International Journal of Phytoremediation, 1999ABSTRACT Willow is shown to be able to accumulate high levels of heavy metal ions such as cadmium and zinc. The properties of willow to be used in phytoextraction therefore have been studied. In this article, results from different studies on heavy metals and willow have been used to demonstrate the capacity and possibility of using Salix in ...

Phytoextraction of copper by cicerarientum
International Journal of Pharma and Bio Sciences, 2016Environmental pollution is a global problem that affects both the developing and developed countries. To an equal extent both human and natural processes contribute to environmental pollution. The contaminants are can be either organic or inorganic.

Wastewaters often contain an array of economically valuable elements, including elements considered critical raw materials and elements for fertilizer production. Plant-based treatment approaches in constructed wetlands, open ponds, or hydroponic systems represent an eco-friendly and economical way to remove potentially toxic metal(loid)s from ...

Critical Assessment of Chelant-Enhanced Metal Phytoextraction
Environmental Science & Technology, 2006Chelant-enhanced phytoextraction has received a lot of attention in the past decade. In theory, this technique could cleanse metal polluted soils by solubilizing contaminating metals, allowing them to be taken up by plants that would subsequently be removed from the site.

Chelate-assisted phytoextraction of mercury in biosolids
Science of The Total Environment, 2011Mercury contaminated stockpiles of biosolids (8.4 mg kg⁻¹ Hg) from Melbourne Water's Western Treatment Plant (MW-WTP) were investigated to evaluate the possibility of their Hg chelate-assisted phytoextraction. The effects of ammonium thiosulphate (NH₄)₂S₂O₃, cysteine (Cys), nitrilotriacetic acid (NTA), and potassium iodide (KI) were studied to mobilize

Factors Affecting Phytoextraction: A Review
Pedosphere, 2016Abstract Hyperaccumulators concentrate trace metals and heavy metals in their shoots when grown in metal-contaminated soils and these trace metal-loaded plants may be removed by harvesting the fields. Studies exploring the beneficial role of these hyperaccumulators to clean up the environment have led to the development of phytoextraction.

Approaches for enhanced phytoextraction of heavy metals
Journal of Environmental Management, 2012The contamination of the environment with toxic metals has become a worldwide problem. Metal toxicity affects crop yields, soil biomass and fertility. Soils polluted with heavy metals pose a serious health hazard to humans as well as plants and animals, and often requires soil remediation practices.
