  1. 1. 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. 2. 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

  4. 3. Environmental transformations of Manganese and Manganese oxide nanoparticles

    University essay from KTH/Materialvetenskap

    Author : Lundberg Annie; [2020]
    Keywords : ;

    Abstract : Engineered nanoparticles (NPs) are produced in increased quantities. Due to this increase, itis vital to understand the full lifecycle and fate of these NPs to prevent any possible environmental stress. READ MORE

  5. 4. Long-term application of digestate and biofuel ash to arable soil : effects on the solubility of Cd, Al and trace metals as evidenced by simulated scenarios

    University essay from SLU/Dept. of Soil and Environment

    Author : Elias Bäckström; [2018]
    Keywords : cadmium; fertilizer; Visual MINTEQ;

    Abstract : The importance of nutrient recycling could not be emphasized enough in to-day’s society. Reduction of waste as well as recycling of nutrients would be the result if ash and biogas digestate could be used as fertilizer. However, the solubility of Cd, Al and micronutrients might be affected in a different way than by standard fertilizers. READ MORE

  6. 5. Investigation of the origin of salt in coastal aquifers and assessment of metals in the aquatic environment : River Drin and River Vjosa, Albania

    University essay from KTH/Vatten- och miljöteknik

    Author : Maximilian von Bahr; Ida Gomez Bergström; [2018]
    Keywords : Albania; aquifers; bioavailability; Drin; groundwater; isotope analysis; metal speciation; river; saltwater intrusion; Vjosa;

    Abstract : The preservation of freshwater aquifers is one important task of managing natural resources today. Intrusion of saltwater from the sea into the groundwater might occur in coastal-near areas and can affect the freshwater quality negatively. READ MORE
