Approaches for enhanced phytoextraction of heavy metals

Journal of Environmental Management, 2012
The 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.

Enhanced Phytoextraction: In Search of EDTA Alternatives

International Journal of Phytoremediation, 2004
Enhanced phytoextraction proposes the use of soil amendments to increase the heavy-metal content of above-ground harvestable plant tissues. This study compares the effect of synthetic aminopolycarboxylic acids [ethylenediamine tetraacetatic acid (EDTA), nitriloacetic acid (NTA), and diethylenetriamine pentaacetic acid (DTPA)] with a number of ...

Phytoextraction of copper by cicerarientum

International Journal of Pharma and Bio Sciences, 2016
Environmental 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.

Use of Willow in Phytoextraction

International Journal of Phytoremediation, 1999
ABSTRACT 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: Where’s the action?

Journal of Geochemical Exploration, 2015
Abstract Many articles concerning phytoextraction of trace elements state that it is “an emerging technology that can be used for the low-cost clean-up of contaminated land…”. Given the lack of commercial phytoextraction operations or even successful field trials, we sought to determine whether phytoextraction could ever compete with existing ...

Phytoextraction of Toxic Metals

Journal of Environmental Quality, 2002
ABSTRACTRemediation of sites contaminated with toxic metals is particularly challenging. Unlike organic compounds, metals cannot be degraded, and the cleanup usually requires their removal. However, this energy‐intensive approach can be prohibitively expensive. In addition, the metal removing process often employs stringent physicochemical agents which

Phytoextraction of Heavy Metals

2020
Heavy metals are considered as the major classes of a contaminant in nature. Heavy metal contamination from fertilizers, metal mining, and industrial activities leads to toxic effects on humans and other organisms. Although the toxic effects of these elements have been recognized for a long time, exposure to these elements continues.

Economics of Willow Pyrolysis After Phytoextraction

International Journal of Phytoremediation, 2008
The Campine is a vast cross-border area in the northeast of Belgium and southeast of the Netherlands that has been contaminated with heavy metals. As traditional excavation techniques are too expensive, phytoremediation is preferred. Economically viable conversion techniques for the biomass are researched in order to lower reclamation costs and to ...

A phytoextraction trial strengthened by Streptomyces pactum and plant nutrients: In view of plant bioindicators and phytoextraction indices

Environmental Pollution, 2020
The present work was done to explore the joint effect of Streptomyces pactum (Act12) and plant nutrients on phytoremediation of smelter-contaminated soils. The physiological indicators and phytoextraction indices of potherb mustard (Brassica juncea, Coss) grown in Act12 inoculated soil with or without Hoagland's solution (H), humic acid (HA) and peat ...

Phytoextraction Options

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 ...
