  • Compressibility of Contaminated Fine-Grained Soils

    An experimental study was performed to investigate factors that control the compression index of contaminated soils and to evaluate the applicability of the correlations proposed by Skempton (1944) and Arulanandan et al. (1983) for contaminated soils. The literature search indicated that the compressibility of a soil depends on mechanical as well as physicochemical factors. The addition of ...

  • Common Treatment Train for Radionuclides

    A treatment train is the combination of different treatment technologies. A system diagram of a common treatment train for radionuclides is illustrated below. Radionuclide contaminated soil is first excavated from the contamination soil and transported to a vitrification site. During vitrification, the contaminated soil is molten at extremely high temperatures. Radionuclides are incorporated into ...

  • Detoxification of chromium slag and contaminated soil

    Chromium slag and contaminated soil are significant risks to human health. Their detoxification is a difficult problem. In this study, we tried to detoxify the chromium slag and contaminated soil by a solid reduction method. The final product is ceramist. The mechanism and process of detoxification of chromium slag and contaminated soil were studied. The residues of Cr (VI) are lower than 0.004 ...

  • Government bill regulating contaminated soils in Catalonia

    The region of Catalonia in Spain has developed a Government bill regulating Contaminated Soils in order to comply with both National Law 10/1998 of 21st April on Waste, and Royal Decree 9/2005 of 14th January, by which it is established the list of soil polluting activities and the standard criteria to declare a soil as contaminated. This decree is based upon the necessity that all Autonomous ...

  • Estimation of OCDD degradation rate in soil

    The current concentrations of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) were determined in soils contaminated with Chinese technical product sodium pentachlorophenate (Na-PCP). The estimated half-life of octachlorodioxin (OCDD) was about 14 years in contaminated soils based on the local historical record and mass balance calculation during the past 43 years (1960-2003). The ...

  • In Situ Treatment Technologies for Contaminated Soil

    Compared to excavation and ex situ treatment, the use of these technologies offers several benefits, such as addressing deep contamination and generally costing less. The summary for each in situ technology includes a basic description of the technology, its implementation, applicability based on contaminants and site characteristics, general limitations, costs, and status of the ...

  • Germination and growth of six plant species on contaminated soil with spent oil

    Abstract: Effects of contaminated soil with spent oil on germination, above ground height and biomass of six herbaceous plant species were investigated by conducting a general phytotoxicity test and growth inhibition assessment. Six local plant species were used in order to investigate plant’s ability to germinate and survive in a gradient of contaminated soil with spent oil. The species ...

  • Effect of amendment on phytoextraction of arsenic by Vetiveria Zizanioides from soil

    Abstract: The present study was undertaken to evaluate the growth response of Vetiveria zizanioides amended with organic amendments to arsenic (As) in contaminated soils and its ability to sequester As. The test results indicate that the plants exhibited high tolerance to As in the soils and their normal growth continued even though As concentration reached 500 mg/kg. However, when As ...

  • Treatment of Oil-Contaminated Soils for Identification and Classification

    An experimental investigation was performed to evaluate the effects of oil contamination on soils and to establish a methodology to identify and classify contaminated soils. Identification and classification tests were performed before treatment, cleaning, stabilization, or disposal of contaminated soils.There are no standards for identification and classification of contaminated soils. ...

  • Extraction of lead and cadmium from soils by Cysteine and Glutathione

    Received for publication December 17, 2008. Metal-thiol complexes can enhance metal uptake by plant roots and microorganisms, therefore it is important to determine whether thiols effectively solubilize these metals from the soil matrix. Extractions were conducted by combining 1 g contaminated soil and 10 mL of 10 mmol L–1 thiol solution and shaking for 1 h. Both cysteine and glutathione ...

  • Remediation Of MTBE Contaminated Soil And Groundwater

    Methyl tertiary-butyl ether (MTBE) is a fuel additive made, in part, from natural gas. Since 1979, it has been used in the United States as an octane enhancing replacement for lead, primarily in midand high-grade gasoline at concentrations as high as 8 percent (by volume). Since the mid-1980s, it has been widely used throughout the country for this purpose. It is also used as a fuel oxygenate at ...

  • Common Treatment Train for Nonhalogenated SVOCs

    A treatment train is the combination of different treatment technologies. A system diagram of a common treatment train for nonhalogenated SVOCs is illustrated below. A thermally enhanced soil vapor extraction system is used to pull SVOC vapor from the contaminated soil. Electrodes are installed in the contamination zone to enhance the desorption of SVOCs from the contaminated soil. The ...

  • Comparison of extractability of Cd, Cu, Pb and Zn with sequential extraction in contaminated and non-contaminated soils

    Various extraction procedures were employed for measuring extractable concentrations of potential toxic elements in soil. The extractability of Cd, Cu, Pb and Zn in four contaminated and four non-contaminated soils of Japan, was compared by single extraction (CaCl2, DTPA, NH4Cl, 0.1 M HCl and 1 M HCl ) and sequential extraction procedures [(six operationally defined chemical phases, viz. water ...

  • Simultaneous removal of polycyclic aromatic hydrocarbons and copper from soils using ethyl lactate-Amended EDDS solution
