16. Weathering and water quality in an area with mineralized till, Liikavaara, northern Sweden
Sammanfattning : Avhandlingen består av tre artiklar som behandlar olika aspekter på vittring och vattenkvalitet i området vid kopparfyndigheten Liikavaara Östra i norra Norrbotten. Moränen i området har naturligt förhöjda metallhalter, särskilt av koppar, och i lic-avhandlingen redovisas med olika metoder att naturligt vittring i detta område kan leda till förhöjda metallhalter i lokalt grundvatten i jämförelse med ett referensområde med låga metallhalter i moränen.

17. Hydrogeochemistry and spatial variability of arsenic and other trace elements in the Lower Katari Basin around Lake Titicaca, Bolivian Altiplano. : Impact on drinking water quality and groundwater management
Sammanfattning : Arsenic (As) contamination in drinking water is a world-wide problem. Thenatural origin of As, its mobility and transport are of great interest in BolivianAltiplano (Lower Katari Basin: LKB and Sothern Poopó Basin: SPB) due topresence of mineral ore deposits, brines, hot springs and volcanic rocks.

18. Dynamics of Spent Nuclear Fuel Dissolution : Impact of Catalysis, Matrix Composition and Time Evolution
Sammanfattning : Worldwide, nuclear power produces a large portion of the electricity that we consume every day. While nuclear energy comes with certain advantages, waste originating from its use is of particular concern. LÄS MER
19. Coupled processes in seasonally frozen soils : Merging experiments and simulations
Sammanfattning : Soil freezing/thawing is of importance in the transport of water, heat and solute, with coupled effects. Due to complexity in soil freezing/thawing, uncertainty could be influential in both experimentation and simulation work in frozen soils. LÄS MER
20. Stability and sorption capacity of montmorillonite colloids : Investigation of size fractional differences and effects of γ-irradiation
Sammanfattning : Bentonite clay is intended to form one of the barriers in most repositories of spent nuclear fuel located in granite. One important function of the bentonite barrier is to retard transport of radionuclides in the event of waste canister failure. Bentonite has a high sorption capacity of cations and its main constituent is montmorillonite. LÄS MER
