Phytoremediation, the use of plants and their associated microbes to remedy contaminated soils, sediments, and groundwater, is emerging as a cost-effective and environmentally friendly technology. Due in large part to its aesthetic appeal, this technology has gained increasing attention over the past 10 years. Phytoremediation uses different plant processes and mechanisms normally involved in t...

The soil bacterial diversity is one of the most important indicators to evaluate the effect of phytoremediation. In this study, the technologies of Sequence-Related Amplified Polymorphism (SRAP) and 16S rRNA gene sequence analysis were used to evaluate the soil bacterial diversity after phytoremediation in a barren rare earth mined area. The results showed that the plant density was remarkably ...

This paper reviews the potential for using trees for the phytoremediation of heavy metal-contaminated land. It considers the following aspects: metal tolerance in trees, heavy metal uptake by trees grown on contaminated substrates, heavy metal compartmentalisation within trees, phytoremediation using trees and the phytoremediation potential of willow (Salix spp.).

Increased soil pollution with heavy metals due to various human and natural activities has led to a growing need to address environmental contamination. Some remediation technologies have been developed to treat contaminated soil, but a biology-based technology, phytoremediation, is emerging. Phytoremediation includes phytovolatilization, phytostabilization, and phytoextraction using hyperaccum...

Selenium (Se) is an essential trace element for humans and animals but at high concentrations, Se becomes toxic to organisms due to Se replacing sulfur in proteins. Selenium biofortification is an agricultural process that increases the accumulation of Se in crops, through plant breeding, genetic engineering, or use of Se fertilizers. Selenium phytoremediation is a green biotechnology to clean ...

Phytoremediation is an emerging technology, which uses plants and their associated rhizospheric microorganisms to remove pollutants from contaminated sites. This plant based technology has gained acceptance in the past ten years as a cheap, efficient and environment friendly technology especially for removing toxic metals. Plant based technologies for metal decontamination are extraction, volat...

Leaching of heavy metals and other contaminants from soils poses a significant environmental threat as it affects the quality of downstream water bodies. Quantifying these losses is particularly important when employing phytoremediation approaches to reduce soil contamination, as contaminant escaping the system through leaching cannot be taken up by vegetation. Despite its undoubted importance,...

Phytoremediation, the use of plants to remediate sites contaminated with organic and inorganic pollutants, and phytomining, the technology involved in extracting the pollutants removed for commercial purposes, are rapidly-growing industries with multi-million dollar markets. This solar-driven, green technology is often favored over more conventional methods of clean-up due to its low cost, low ...

The role agronomy plays in the management of phytotechnologies is a significant example of the answers that the agrosciences can offer to the issues of society in the field of Green Remediation. This paper reports a study designed to test how the principles of classical plant growth analysis can be used in the field of phytoremediation. In the framework of a phytoremediation field trial set up ...
