Remediation techniques play a key role in fu lly cleaning up the contaminants in soils and groundwater. This work is focused on the application of a remediation technique that maintains soil ecological and environmental services to the extent possible as well as search for alternative sustainable land uses. Soil sediments actively adsorb the ionic form of mercury, while iron oxides adsorb mercury ions in neutral soils. Controlled thermal desorption … 2. @article{osti_1265799, title = {In situ remediation technologies for mercury-contaminated soil}, author = {He, Feng and Gao, Jie and Pierce, Eric and Strong, P. J. and Wang, Hailong and Liang, Liyuan}, abstractNote = {A pollutant that poses significant risks to humans and the environment is mercury from anthropogenic activities. Appendix A contains a map … However, recent research has found that biochar, a charcoal produced by superheating agriculture or forestry waste in the absence of oxygen, holds promise as a low cost, “green” alternative. Mercury from anthropogenic activities is a pollutant that poses significant risks to humans and the environment. However, in the absence of organic matter, mercury becomes mobile and evaporates or can leach on to groundwater (1). In Situ Remediation and Stabilization Technologies for Mercury in Clay Soils Cabrejo, Elsa (DOE Fellow), Florida International Univ. Mercury remediation continues on the South River ... done either through excavating contaminated soil or capping the banks. For the cleanup of non-hazardous mercury-contaminated soils, the approved remediation methodology includes excavation and disposal of contaminated soils at an approved Subtitle D (sanitary) landfill. Mercury from anthropogenic activities is a pollutant that poses significant risks to humans and the environment. Remediation pathways include transfer of contaminants alone, or with Then, we systematically summarize the soil remediation technologies, including thermal desorption, electrokinetic remediation, soil washing, chemical stabilization, plant and microbial remediation. concentrations are less than 4.0 mg/kg. Mercury soil contamination is an important environmental problem that needs the development of sustainable and efficient decontamination strategies. The technologies addressed in this manuscript include chemical/plant stabilization and volatilization. Finally, we also discuss the potential challenges and future perspectives for remediation of Hg-contaminated soils. Mercury soil contamination is an important environmental problem that needs the development of sustainable and efficient decontamination strategies. In soils, mercury remediation can be technically challenging and costly, depending on the subsurface mercury distribution, the types of mercury species, and the regulatory requirements. Conventional methods of remediating mercury-contaminated soil – such as adding activated carbon – can be quite expensive to apply on a large scale. Toxicity of mercury T … Remediation refers to the process of environmental cleanup of contaminated sites and the techniques to reduce or eliminate contamination from soil or groundwater. Furthermore, organic matter adsorbs mercury ions in acidic environments. In soils, mercury remediation can be technically challenging and costly, depending on the subsurface mercury distribution, the types of mercury species, and the regulatory requirements. Sparging is one of the most common methods of in situ remediation, so this something to consider when looking at a soil remediation method.
