  • Estuarine sediment controls on trace metal distributions

    Creator:
    Davies-Colley, Robert J.
    Abstract:
    Sediments are the major compartment in aquatic environments for many materials of toxic or nutrient concern. The lack of knowledge of the phase associations of toxic metals in sediments is the largest deficiency in our understanding of the environmental hazard posed by metal contamination. This study examined the sedimentary partitioning...

  • Adsorption of hexavalent and trivalent chromium to a clayey silt soil : batch kinetic and equilibrium studies

    Creator:
    Bean, Gregory R.
    Abstract:
    Chromium, an element of widespread use, is toxic in some forms. Improper disposal of waste chromium products has resulted in contamination of many sites throughout the United States, including the United Chrome Products Superfund site in Corvallis, Oregon. A better understanding of chromium chemistry is needed to facilitate the remediation...

  • Chromium (VI) sorption in soils : chemical behavior and solute transport modeling

    Creator:
    Schroth, Martin Herbert
    Abstract:
    Chromium spills on soils are causing severe groundwater contamination problems. To increase the performance of cleanup methods, the chemical behavior of chromium in soils and its transport through soils have to be understood. The objectives of this research were to investigate the sorption characteristics of chromium(VI) in soil and to...
