16. Sulfur isotopes used as a tracer of acidification reversal, dispersion of acid mine drainage and sulfur dynamics in small and large catchments

17. Mobilization of metals from mining wastes and the resuspension of contaminated sediments
Sammanfattning : In some environmental situations, environmental effects caused by elevated metals resulting from past mining and smelting activities can be observed in nearby receiving water bodies several decades after mine and smelter closure. There is a growing need for managing the hazardous solid wastes such as mining wastes as well as for assessing water quality and for sustainable management of sediment quality. LÄS MER
18. Sulphide oxidation and geochemical processes in mine tailings
Sammanfattning : The generation of acid mine drainage (AMD) from oxidation of sulphide- bearing waste is a world wide problem, due to low pH levels and the release of metals to recipients. It is therefore important to understand the fundamental geochemical processes occurring in mine waste. LÄS MER
19. Sulfidic mine waste microorganisms in an ecological context
Sammanfattning : The focus of this thesis are the microorganisms found in sulfidic minewaste and their ecology. The microorganisms are investigated from the point of view of being an important, if not the most important, factor in the production of acid rock drainage (ARD). The thesis is a summary of several studies. LÄS MER
20. An integrated systems approach to biogeochemical processes: Evalution of the control mechanism of trace metal speciation in a wetland streamenvironment affected by acid mine drainage
