Phytoextraction of Toxic Metals

Journal of Environment 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 ...

Metal Phytoextraction—A Survey of Potential Risks

International Journal of Phytoremediation, 2005
Metal phytoremediation, and more specifically, phytoextraction, utilizing hyperaccumulators is one of the most exciting new environmental technologies developed over the past decade (Baker et al., ...

Chelate-assisted phytoextraction of mercury in biosolids

Science of The Total Environment, 2011
Mercury 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

Phytoextraction of Ni, Pb and, Cd by duckweeds

International Journal of Phytoremediation, 2019
Heavy metals phytoextraction potential of swollen duckweed (Lemna gibba Linn.) and lesser duckweed (Lemna aequinoctialis Welw.) was determined under greenhouse conditions by exposing to untreated industrial/municipal effluent for a period of 21 days. The nickel (Ni), lead (Pb), and cadmium (Cd) concentrations in water samples were measured weekly and ...

Factors Affecting Phytoextraction: A Review

Pedosphere, 2016
Abstract 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.

Phytoextraction of cadmium with Thlaspi caerulescens

Plant and Soil, 2003
The in situ phytoextraction of cadmium from soils can only be achieved using plants that are both tolerant to high Cd concentrations and able to extract sufficient amounts of the metal. However, very few plant species are capable of remediating Cd polluted soils in a reasonable time frame.
