  • Analyzing sulfur in soil and sediment with handheld XRF

    Background Sulfur creates more than nasty odors. Exposure to low levels (0-10ppm) of hydrogen sulfide (H2S) causes irritation of eyes, nose, and throat; higher levels can cause headaches, dizziness, nausea and vomiting, coughing, and breathing difficulty. H2S and numerous other odor-causing compounds are generated as a result of organic material decomposition. In the case of the Muddy River in ...

  • Determination of the feasibility of using a portable x-ray fluorescence (XFR) analyzer in the field for measurement of lead content of sieved soil

    Soil samples collected in housing areas with potential lead contamination generally are analyzed with flame atomic absorption spectrometry (FAAS) or other laboratory methods. Previous work indicates that field-portable X-ray fluorescence (XRF) analysis is capable of detecting soil lead levels comparable to those detected by FAAS in samples sieved to less than 125 μm in a laboratory. A ...

  • Evaluation of Soil Environment after Saline Soil Reclamation of Xinjiang Oasis, China

    Land degradation resulting from soil salinity is a primary problem in arid farmland. This study clarifies the characteristics and regulation of reclaimed salinized farmlnd in a desert oasis. As a case study, we examined an alluvial fan oasis in the Manas River Valley using fixed position experiments, spacial substitutes, and a trend estimation model derived from principal component analysis. In ...

  • Determination of Deformation Properties of Collapsible Soils

    Mechanical properties of loessial soils are the functions of their in-situ physical conditions, geological history, as well as actual load distribution at the site of interest. It is well known that the bearing capacity of loesses and loessial soils decreases with an increase in their porosity and water content. Physical and mechanical properties of soils can be determined by different laboratory ...

  • Effects of soil solution`s constituents on proton NMR relaxometry of soil samples

    Proton nuclear magnetic resonance (1H NMR) relaxometry has been used to analyze pore size distributions of wet porous samples. To make this method applicable to soil samples, knowledge about contribution from the soil solution to the total proton relaxation is needed. We extracted soil solutions from nine soil samples and determined transverse proton relaxation rates, the concentration of Fe, Mn, ...

  • Pollution retention capabilities of roadside soils

    ABSTRACTRunoff from highways contains significant loads of heavy metals and hydrocarbons. According to German regulations, it should be infiltrated over embankments to support groundwater-recharge. To investigate the decontaminating effect of greened embankments, soil-monoliths from highways with high traffic densities were taken. Soils were analyzed to characterize the contamination in relation ...
