  1. 11. Spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, northern Tanzania

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Henriette Nishimwe; [2023]
    Keywords : Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling; Arsenic; Fluoride; Groundwater; Mobilization; Mount Meru; Geochemical and Spatial Modelling;

    Abstract : In Tanzania, approximately 76% of the drinking water supplies is dependent on groundwater sources. However, the groundwater in north Tanzania is susceptible to contamination by arsenic and fluoride. This study examines the spatial analysis of arsenic and fluoride mobilization in groundwater around Mount Meru, located in northern Tanzania. READ MORE

  3. 12. Bio-enhanced silicate weathering : Coupled to sequestration of CO2

    University essay from Uppsala universitet/Limnologi

    Author : Marcus Westholm; [2022]
    Keywords : NETs; Bio-enhanced weathering; Carbon capture;

    Abstract : Weathering of silicate minerals has long been a known source of natural CO2 sequestration, that could be increased in the presence of microorganisms. Bio-enhanced weathering of silicate minerals could increase the sequestration of CO2 from the atmosphere. READ MORE

  4. 13. Solubility of arsenic in untreated and ZVI-treated contaminated aquifer material

    University essay from SLU/Dept. of Soil and Environment

    Author : Oscar R. Davies; [2022]
    Keywords : Hjältevad; zerovalent iron; phosphate extraction; Oxalate extraction; Visual MINTEQ; geochemical modelling;

    Abstract : Arsenic (As) is a toxic element to all life and exists in nature both naturally and anthropogenically. Naturally As contaminated soils are formed due to high geogenic background As concentrations which is released when bedrock is eroded. Asia is a continent with a high amount of naturally As contaminated soils and groundwater. READ MORE

  5. 14. Geophysical Data from Norrbotten, Sweden - Evidence for the Presence of a Crustal Scale Fault?

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Jimmy Markström; [2022]
    Keywords : Self-Organizing Maps; Magnetic Anomaly; Radioisotopes; Geological Faults;

    Abstract : The method of combining multiple geophysical, geological, or geochemical datasets can reveal patterns of otherwise hidden features in the Earth’s crust. This may aid in geological mapping, locating economic mineral deposits and for general anomaly/feature detection. READ MORE

  6. 15. Uranium Mineralizations at Kiirunavaara,Northernmost Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Diego Segovia Menard; [2022]
    Keywords : kiirunavaara; uranium; EPMA; water; hydrothermal;

    Abstract : In recent years, a variably high amount of uranium (U) and radon (Rn) were found in the water and airof the Kiirunavaara mine in Kiruna, northern Sweden. The Swedish Agency for Marine and WaterManagement (Havs och vattenmyndigheten) has maximum limits for “special polluting substances” inwater that is released to natural recipients (HVMFS 2019:25), therefore, the mining company LKAB,owner and operator of the Kiirunavaara mine, decided to conduct a study to investigate the issueregarding these findings, triggering this master thesis.
