As the number of leaking underground fuel tank sites with MTBE contamination continues to grow, there is a need to develop cost-effective solutions for treatment of soil and water contamination. MTBE poses special challenges due to its physicochemical properties, in particular high solubility and low Henry’s constant, low affinity for sorption, and very slow rate of microbial degradation. Advan...

Soils contaminated with radionuclides, particularly 137Cs and 90Sr, pose a long-term radiation hazard to human health through exposure via the foodchain and other pathways. Remediation of radionuclide-contaminated soils has become increasingly important. Removal of the contaminated surface soil (often up to 40 cm) or immobilization of radionuclides in soils by applying mineral and chemical amen...

<span>Soil quality is rich in various substances, as well a variety of uses for life, which leads to the potential pollution. Once soils are polluted, remediation mitigative and must be carried out, has been focus many studies so far. However, preventive novelty this study, aims prepare predictive methods. This literature review over last ten years, related soil indicators through respira...

Using plants for the remediation of soils contaminated with heavy metals is an economical, cheap, and effective strategy. The goal of this research was to study the effect of sewage sludge and drought stress on the remediation of cadmium in soil, root uptake by corn plant. This study was carried out on corn in factorial design experiment based on completely randomized design with three replicat...

supercritical fluid extraction (scfe) is a soil remediation technology. at present, only a few companies are using from this method, all of which are technical based on conventional methods of extraction such as soilex solvent extraction. because of the hard enforcement of environmental conservation law, using green technology seems imperative. this paper endeavors to carry out the feasibility ...

Soil Fungi May Help in Lead Remediation Lead contaminates soil in many urban areas. Investigators have discovered that lead can be transformed by multiple soil fungi into a stable form known as chloropyromorphite, suggesting a potential new tool for cleaning up soil lead contamination. This ability of the fungi may help them to survive in contaminated locations. The authors write that “fungal m...

To assess soil and groundwater quality two generic (i.e. multifunctional) risk-based standards, Target and Intervention Value, have been developed, in the framework of the Dutch Soil Protection Act. These standards allow soil and groundwater to be classified as clean, slightly contaminated or seriously contaminated. The Target Value is based on potential risks to ecosystems, while the Intervent...
