2. A model of pH and redox buffer depletion in waste landfills
Abstract : The geochemical processes governing the release of heavymetal contaminants from solid waste materials have been studiedexperimentally and modelled using a mass balance approach. Theaim of the modelling work was to develop calculation tools thatcan be used to predict the release rate of heavy metals fromwaste heaps or landfills. READ MORE

3. Evolution of the groundwater geochemistry in sulphide bearing tailings remediated by applying till cover, Kristineberg, Northern Sweden
Abstract : At the Kristineberg mine in northern Sweden, sulphide-rich tailings were remediated in 1996 by applying till covers. The sulphides were isolated from the atmosphere to prevent oxidation. READ MORE

4. Phytostabilisation : use of wetland plants to treat mine tailings
Abstract : Mine tailings can be rich in sulphide minerals and may form acid mine drainage (AMD) through reaction with atmospheric oxygen and water. AMD contains elevated levels of metals and arsenic (As) that could be harmful to animals and plants. READ MORE

5. Hydrothermal alteration of organic matter at spreading centers
Abstract : Alteration of organic matter, mainly amino acids, at sub-seafloor hydrothermal conditions has been investigated by performing laboratory experiments and by studying deep-sea sediments from hydrothermally active areas on the northern Juan de Fuca Ridge, northeast Pacific Ocean.Quaternary sediments from Middle Valley and the eastern flank of the Juan de Fuca Ridge recovered during the Ocean Drilling Program Legs 139 and 168 have been analyzed for total hydrolyzable amino acid concentrations, individual amino acid abundances and stereochemistry in order to evaluate the effects of hydrothermal stress on the decomposition of sedimentary amino acids.
