    Contaminant Behavior in the Environment

    1. Models of Contaminant Migration: The Role of Chromatographic Models

    2. A summary of my research on contaminant migration
    3. Contaminant Accumulation During Transport Through Porous Media

    4. A coupled geohydraulic/geochemical transport model is solved numerically. Even when the leakage from a waste repository produces negligible concentrations in the escaping water ("primary leakage"), a considerable contaminant inventory can become associated with the solid phase of the porous medium ("secondary repository"). A simple process is shown to be able to both remobilize that secondary repository and achieve soluble contaminant concentrations far in excess of those in the primary leakage.


      I hope you'll find the above papers helpful. They seem quite exotic in environmental geochemistry, and I'll be happy to help you when you think you have problems in following the formalism.

      Also, have a look at the research at the Dept. of Petroleum Engineering, School of Earth Sciences, Stanford University, Stanford, CA 94307, USA, e.g. at Analytical Multicomponent Displacements by Birol Dindoruk and Lynn Orr's research on carbon dioxide injection into deep geological formations.



       
    5. Evaluation of the Potential Hazard originating from Radioactive Waste
    6. Calculation of Particle Removal Velocities in the Mecklenburg Bight Based on the Thorium Deficit

    7. The Baltic Sea is continuously being fed with large amounts of contaminants. They adsorb to the particulate matter suspended in the sea water. This particulate matter is constantly generated and settling onto the sea bed. This way the contaminants are continuously being removed from the mobile phase of the Baltic ("sedimentation"). If one knows the particulate removal rates one can -on the basis of a balance between feed and removal- calculate the stationary mobile contaminant inventory as a function of the parameters determining the settling process. 
      The presented research shows a method to determine the particulate removal rate.
