Remediation of Heavy Metal Contaminated Soils: Phytoremediation as a Potentially Promising Clean-Up Technology
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...
متن کاملBiosurfactant-facilitated remediation of metal-contaminated soils.
Bioremediation of metal-contaminated wastestreams has been successfully demonstrated. Normally, whole cells or microbial exopolymers are used to concentrate and/or precipitate metals in the wastestream to aid in metal removal. Analogous remediation of metal-contaminated soils is more complex because microbial cells or large exopolymers do not move freely through the soil. The use of microbially...
متن کاملCoupled Electro-kinetic Remediation and Phytoremediation of Metal(loid) Contaminated Soils
Soil contamination with heavy metals and metalloids has become a serious environmental problem with rapid industrialization and urbanization [1-3]. Generally, the contamination is resulted from anthropogenic activities such as mining, domestic waste discharge, agricultural production and industrial activities. Heavy metals and metalloids such as Cd, Pb, Cr, Cu, Hg, Cs, Se, Zn and As enter the f...
متن کاملThe use of plants for remediation of metal-contaminated soils.
The use of green plants to remove, contain, inactivate, or degrade harmful environmental contaminants (generally termed phytoremediation) is an emerging technology. In this paper, an overview is given of existing information concerning the use of plants for the remediation of metal-contaminated soils. Both site decontamination (phytoextraction) and stabilization techniques (phytostabilization) ...
متن کاملProximal spectral sensing to monitor phytoremediation of metal-contaminated soils.
Assessment of soil contamination and its long-term monitoring are necessary to evaluate the effectiveness of phytoremediation systems. Spectral sensing-based monitoring methods promise obvious benefits compared to field-based methods: lower cost, faster data acquisition and better spatio-temporal monitoring. This paper reviews the theoretical basis whereby proximal spectral sensing of soil and ...
