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 crop disposal—an unsolved problem

Environmental Pollution, 2004
Several methods of contaminated crop disposal after phytoextraction process (composting, compaction, incineration, ashing, pyrolysis, direct disposal, liquid extraction) have been described. Advantages and disadvantages of methods are presented and discussed.

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.

Chenopodium: a prospective plant for phytoextraction

Acta Physiologiae Plantarum, 2007
Leaf samples were collected from 40 accessions of Chenopodium spp. and assessed for six heavy metals (Fe, Zn, Cu, Ni, Cr and Cd) accumulation to explore the use of Chenopodium for phytoextraction of heavy metals. The results suggest that Chenopodium spp.

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.

Phytoextraction and Phytostabilization: Technical, Economic, and Regulatory Considerations of the Soil-Lead Issue

1999
This chapter explores two emerging remediation technologies based on “agronomic” or “low-tech” solutions. Several approaches have been investigated to overcome the obstacles described above. Some researchers have examined the fundamental soil and plant processes influencing plant uptake of metals and tried to optimize these processes by agronomics, and

Biodegradable Chelant-Assisted Phytoextraction

2018
The 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 ...
