  1. 6. Filter Materials for Sorption of Cu and Zn in Stormwater Treatment: A Batch Equilibrium and Kinetic study

    University essay from Luleå tekniska universitet/Arkitektur och vatten

    Author : Per-Albin Norman; [2018]
    Keywords : Stormwater; Treatment; Metals; Sorbents; Batch equilibrium test; Isotherms; Kinetic test; Catch basin inserts;

    Abstract : Urban stormwater is today recognized as a significant source of pollution that has contributed to the deterioration of water quality in lakes and streams. Of the pollutants, metals are commonly occurring in stormwater and can cause major damage when released into the receiving waters. READ MORE

  3. 7. Interpretation of geophysical and geochemical data in a 3D geological model construction of a contaminated site

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Haoyu Wei; [2018]
    Keywords : Halogenated hydrocarbon; Geophysics; DCIP; GeoScene3D; Groundwater chemistry; Earth and Environmental Sciences; Technology and Engineering;

    Abstract : The Alingsås dry-cleaning facility is one of the heavily halogenated hydrocarbon contaminated sites in Sweden. The source of contamination dates back to the 1970s when a large scale tetrachloroethylene leakage outbroke inside the dry-cleaning building. READ MORE

  4. 8. Geochemical Investigation of Arsenic in Drinking Water Sources in Proximity of Gold Mining Areas within the Lake Victoria Basin, in Northern Tanzania

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Enrico Lucca; [2017]
    Keywords : ;

    Abstract : Access to safe drinking water is a challenge for rural communities in many developing countries. Drinking contaminated water endangers human health and impairs social and economic development. Arsenic (As) is a metalloid widely distributed into the environment and is highly toxic in its trivalent inorganic form. READ MORE

  5. 9. Solubility of arsenic in Swedish contaminated soils : experiments and modelling

    University essay from SLU/Dept. of Soil and Environment

    Author : Ann-Sophie Heldele; [2016]
    Keywords : arsenic; leaching; pH influence; geochemical modelling; contamination;

    Abstract : Even though arsenic can be found everywhere in the environment, it is phytotoxic and hazardous to human and animal health. Especially arsenic leaching produces contamination of groundwater. READ MORE

  6. 10. Geochemistry of arsenic and heavy metals in pyrite ash : speciation, solubility control mechanisms and geochemical modelling

    University essay from SLU/Dept. of Soil and Environment

    Author : Gunilla Theorin; [2015]
    Keywords : soil contamination; leaching tests; extractions; EDTA; kinetics; surface complexation modelling;

    Abstract : This thesis was part of a project at the Swedish Geotechnical Institute aiming at investigating the geochemistry of heavy metals and arsenic in pyrite ash. The spe-cific aims with this work were to extend the knowledge on solubility control mechanisms of metals in pyrite ash and how the sorption ability of the ash was dependent on content of iron (hydr)oxides.
