  • Content Analysis of Toxic Elements in Soil by Simultaneous ICP

    Contaminated soil not only leads to contamination of untreated drinking water through permeation into river water and rainwater, it adversely affects health when the soil itself is directly ingested as a child puts the ground into a stoma into a play etc. Therefore, assessment of soil toxicity using a defined method is required. I In Japan, the Soil ...

  • Soil Flushing

    Introduction In situ soil flushing is the extraction of contaminants from the soil with water or other suitable aqueous solutions. Soil flushing is accomplished by passing the extraction fluid through in-place soils using an injection or infiltration process. Extraction fluids must be recovered from the underlying aquifer and, when possible, they are recycled. Cosolvent Enhancement Cosolvent ...

  • Hydrologic signature analysis of select organic hydric soil indicators in northeastern Florida

    The magnitude, duration, and return intervals of surface water flooding and dewatering of the landward extent of the hydric soil indicators muck (LM), histic epipedon (LHE), and Histosol (LH) were quantitatively defined, providing a better understanding of the hydrologic conditions maintaining these hydric soil indicators. Land surface elevations were determined for the LM, LHE, and LH at 16 ...

  • Rapid Analysis of Petroleum Hydrocarbons (TPH) in Soil and Water by Infrared Spectroscopy

    In 1988 the US EPA estimated that there were 3 to 5 million underground chemical storage tanks (UST’s) in the United States, of which up to 1% would develop leaks every year. In response to growing concerns about the quality and future availability of safe drinking water, federal and state programs have begun to systematically replace virtually all UST’s installed before 1986 either with above ...

  • Database analysis of US state regulatory guidance for organic surface soil contamination

    This manuscript describes a database of US state regulatory guidance values assembled to examine the guidance applied to the most commonly regulated surface soil contaminants. Guidance values were identified for 994 different contaminants, but there is considerable variability in the number of contaminants regulated by each state and in the values applied to contaminants. Guidance values for the ...

  • Application of spatial Markov chains to the analysis of the temporal–spatial evolution of soil erosion

    Soil and water conservation in the Three Gorges Reservoir Area of China is important, and soil erosion is a significant issue. In the present study, spatial Markov chains were applied to explore the impacts of the regional context on soil erosion in the Xiangxi River watershed, and Thematic Mapper remote sensing data from 1999 and 2007 were employed. The results indicated that the observed ...

  • Environmental Analysis of BTEX Compounds in Soil, Water and Sludge by GC / PID

    Because of the widespread use and history of indiscriminate disposal practices of gasoline and fuel oils, their analysis in environmental samples is in high demand. Gasoline and diesel are both complex mixtures containing up to 400 individual compounds. The BTEX group (Benzene, Toluene, Ethylbenzene, and the Xylenes) are naturally occurring constituents of gasoline and diesel (although also ...

  • Analysis of atrazine and its degradation products in loamy soil by SPE and HPLC

    The degradation and leaching of atrazine and its degradation products (hydroxyatrazine, desethylatrazine, deisopropylatarzine and didealkylatrazine) were studied into loamy soil. An agriculture soil field (50 × 50 sq. feet with brinjal plants) was selected and atrazine spray was carried out once in a year. The irrigation of this plot was carried out once in a month. The sampling of soil was ...

  • Assessment of cement’s dust impact on the soil using principal component analysis and GIS

    To evaluate the impact of the cement’s dust emitted by the eastern Moroccan cement factory (Oujda Holcim) and deposited on the soil of the Ain Lahjar commune, 58 samples of soil were collected around the factory on a radius of 3 km approximately. The physicochemical analyses of the upper 3 cm of the soil surface samples correspond to the pH, electrical conductivity, the chlorides and the oxides ...

  • A Nonlinear One-Dimensional Wave Analysis of a Triaxial Soil Specimen

    A fast triaxial shear device (FTRXD) loads cylindrical soil specimens, displacing the top of the specimen downward and axially at a controlled and very rapid rate. Load and displacement at the specimen top and load at the bottom are measured; specimens are subjected to constant confining pressures. Nonlinear, one-dimensional wave analysis of the specimen was undertaken, using finite-difference ...

  • Multivariate analysis and visualization of soil quality data for no-till systems

    To evidence the multidimensionality of the soil quality concept, we propose the use of data visualization as a tool for exploratory data analyses, model building, and diagnostics. Our objective was to establish the best edaphic indicators for assessing soil quality in four no-till systems with regard to functioning as a medium for crop production and nutrient cycling across two Illinois ...

  • Metabolomic analysis of soil communities can be used for pollution assessment

    Here we show that metabolic profiling can be used to assess the changes in biochemical profiles of soil communities living in contaminated sites. We propose the term ‘community metabolomics’ for the application of metabolomics techniques to the study of the entire community of a soil sample. We anticipate our study to be a starting point for the use of this technique to assess how communities ...

  • Kato-Katz analysis technique for Soil-Transmitted Helminthiasis (STH)

    In last October’s newsletter, Sterlitech announced the availability of kits for performing the Kato-Katz  analysis technique for Soil-Transmitted Helminthiasis (STH) in field-based applications, signifying the first time that these kits were available from a source in the United States. ...

  • A soil quality index for reclaimed mine soils

    The quality of soils found in mines is low if they do not receive any reclamation treatment. To our knowledge, there are no still equations to evaluate the quality of metal contaminated mine soils after the application of the reclamation treatments mainly in use today (planting vegetation and amending with wastes). Therefore, the purposes of the present study was (i) to propose a method for ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • Natural Attenuation in Soils

    Introduction Surface and subsurface soils have different characteristics in natural attenuation. Mobile contaminants in subsurface soils diffuse into soil vapor and aqueous phase and thus are relatively easily subject to natural subsurface processes that can attenuate these contaminants. Most high-molecular-weight (persistent) organic and many inorganic contaminants will be immobilized in the ...
