abstract the plants which can be used to clean up the soil of heavy metals contamination are named phytoremedation. phytoremediation has received increasing attention because of its low environmental impact and cost-effectiveness. but, it is slowly process and needs long time. in such reson, chelating agents have been proposed to improve the efficiency of phytoextraction by increasing solubilit...

phytoextraction is a remediation technology that uses plants to remove heavy metals from soil. the success of a phytoextraction process depends on adequate plant yield (aerial parts) and high metal concentrations in plant shoots. a pot experiment was conducted to investigate the combination effects of plants [sunflower (helianthus annuus) and canola (brassica napus)] with soil treatments (manur...

In the present work, we aimed to focus on the identification and characterization of the heavy metal-tolerant plant species growing spontaneously at the tailings site of the Sarcheshmeh copper mine, south of Iran. Our aim was to find the plant species that were potentially useful for phytoextraction purposes. The concentrations of As, Cu, Mo, Ni, Zn, and Re were analyzed in soil as well as in t...

heavy metals contamination is a major environmental problem which requires immediate human attention. the use of plant species to remove pollutants from soils, generally defined as phytoextraction. in order to evaluate phytoextraction of contaminated soils, a pot experiment conducted using two plants barley, canola three kinds of heavy metals (cd, pb, ni) with 3 levels in a completely randomize...

The use of plants for phytoextraction of heavy metals from contaminated soil is limited by the ability of the plants to grow on these soils and take up the target metals, as well as by the availability of the metals for plant uptake in the soil solution. The hypotheses of this study were that the growth-promoting phytohormone auxin (indole-3-acetic acid, IAA) can alleviate toxic effects of meta...

metal pollution has become one of the most serious environmental problems resulting from human activity. phytoremediation utilizes plants to uptake contaminants and can potentially be used to remediate metal-contaminated sites. the present study investigates heavy metal uptake (cd, cr, and ni) from soil by different organs of populus alba and morus alba. for this purpose, cd (40, 80, and 160 m...

Microbacterium spp. isolated from heavy metal (HM)-contaminated environments (soil and plants) can play a role in mobilization processes and in the phytoextraction of HM. Here, we report the whole-genome sequences and annotation of 10 Microbacterium spp. isolated from both HM-contaminated and -noncontaminated compartments.

Phytoextraction is gaining acceptance as a cost-effective and environmentally sound phytoremediation strategy for reducing toxic metal levels from contaminated soils. We hypothesized that the addition of synthetic chelates can increase the amount of bioavailable metal for root uptake, thereby improving the efficacy of phytoextraction. This study was therefore conducted to determine whether the ...

In most developing parts of the world, the rapid expansion of industrial areas leading to uncontrolled processing and utilization of industrial products, agricultural inputs, vehicular emissions and improper disposal of liquid and solid wastes may cause soil to become contaminated with chemical hazards such as heavy metals. Heavy metal contamination of soil may pose risks to humans and the ecos...
