Soil and surface water contamination by used lubricating oil is a common occurrence in most developing countries. This has been shown to have harmful effects on the environment and human beings at large. Bioremediation can be an alternative green technology for remediation of such hydrocarbon-contaminated soil. Bioremediation of soil contaminated with 5% and 15% (w/w) used lubricating oil and a...

Public involvement is critical in sustainable contaminated site management. It is important for China to improve public knowledge and participation, foster dialogue between urban managers and laypeople, and accelerate the remediation and redevelopment processes in contaminated site management. In this study, we collected 1812 questionnaires from nine cities around China through face-to-face int...

Development of remediative techniques for PAH-contaminated soils and evaluation of residual toxicity after remediation are important issues in the assessment of soil quality. To investigate the efficiency of soil remediation technology using biomonitoring assay, soil flushing experiments with surfactant and ecotoxicity tests with Eisenia fetida were carried out for artificially phenanthrene-con...

Low-temperature plasma has exhibited high efficiency for fast remediation of organic-polluted soil with water content (less than 20%). In the present study, the feasibility of remediation of p-Nitrophenol (PNP) contaminated over-wet soil (water content of 100%) was studied using pulsed corona discharge plasma, which was generated in a needle-plate discharge reactor. Effect of energy input model...

Soil and surface water contamination by organic compounds is a common occurrence in most developing countries. This caused harmful effects on the environment and human beings. Bioremediation can be an alternative green technology for remediation of such hydrocarbon-contaminated soil. Bioremediation of soil contaminated with 5% and 10% (w/w) diesel fuel amended with 10% soy cake (SC), potato ski...

use of electrokinetic technique for remediation of contaminated soils has recently been highly attended to, but there are still concerns regarding the effect of this process on soil microbial activity. in this study, changes in concentration of heavy metals extractable through 4n nitric acid, microbial biomass-c, and microbial coefficient, following electrokinetic remediation of a native soil c...

A mathematical model has been simulated to describe natural in situ bioremediation of contaminated soil. The model equations consist of a system of three non-linear partial differential equations. Sensitivity analysis conducted by numerically solving them, has demonstrated the effect of initial contaminant concentration on the time and mechanism of remediation. The result of simulation indicate...

in recent decades, attention to contamination propagation into soils and underground water has increased, which has led to a rise in the studies on soil contamination problems and methods of in-situ remediation. in this research, effective parameters on oil contamination propagation in soils and underground water have been investigated using fem in order to determine propagation patterns. the m...
