TL;DR: A review of the full-scale and developing technologies that are available for metal removal can be found in this paper, where the main techniques that have been used for removal of metals from contaminated soils and sediments are discussed.
1,376 citations
TL;DR: In this paper, the authors provide an overview of the laboratory research, field demonstration and full-scale application of surfactants for the remediation of contaminated soil and discuss three types of biosurfactants evaluated for their effectiveness They included a lipopeptide called surfactin from Bacillus subtilis, a rhamnolipid from Pseudomonas aeruginosa and a sophorolipids from Torulopsis bombicola.
956 citations
TL;DR: In this paper, the feasibility of using biosurfactants for the removal of heavy metals from sediments was evaluated using batch washing experiments, and it was shown that the metal removal process occurs through sorption of the surfactant on to the soil surface and complexation with the metal, detachment of the metal from the soil into the soil solution and hence association with surfactants micelles.

TL;DR: Sediments dewatering is frequently necessary after dredging to remediate and treat contaminants and few remediation techniques have been commercially used for sediments, but there exists significant demand for further development.
382 citations
TL;DR: Modelling of contaminant migration plays a key role in evaluating natural attenuation as a remediation option and in ensuring that there will be no adverse impact on humans and the environment.

TL;DR: An overview of data published during the last five years on the immobilization of one metalloid, As, and four heavy metals, Cr, Cu, Pb and Zn, in soils, finds that Zn can be successfully immobilized in soil by phosphorus amendments and clays.
1,437 citations
TL;DR: Biosurfactants are surfactants that are produced extracellularly or as part of the cell membrane by bacteria, yeast and fungi as mentioned in this paper, which are used for soil and water treatment.
