  1. 16. Electrodialytic Remediation of PFAS-Contaminated Soil

    University essay from KTH/Vatten- och miljöteknik

    Author : Georgios Niarchos; [2018]
    Keywords : Per- and polyfluoroalkyl substances; Electrokinetic; Ground; Groundwater; Treatment; Electrochemistry; Environment; Per- och polyfluoralkylsubstanser; Electrokinetisk; Grundvatten; Förorening; Elektrokemi; Miljö;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are a group of anthropogenic aliphatic compounds, widelyknown for their environmental persistence and toxicity to living beings. While they are ubiquitous in theenvironment, interest has been focused on contaminated soil, which can act as a primary recipient andsource of groundwater contamination. READ MORE

  3. 17. Sorption of PFOS to different solid components as a function of aqueous chemistry

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Jean Noël UWAYEZU; [2018]
    Keywords : ;

    Abstract : Knowledge of fate and transport of chemical contaminants in the environment is essential for reducing their adverse effects to humans and wildlife. Surface and ground waters serve as drinking water which helps to sustain life. READ MORE

  4. 18. Phosphorus speciation across elevation and vegetation in soils of the subarctic tundra : A solution 31P NMR approach

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Johannes Krohn; [2017]
    Keywords : Climate warming; arctic ecosystems; tundra; phosphorus; Solution 31P NMR;

    Abstract : In tundra, phosphorus (P) is an important macronutrient for plants and microorganisms. A major fraction of P exists as organic compounds in the topsoil which can be mineralized to bioavailable inorganic P. READ MORE

  5. 19. Production, sorption and pathways for dissolved organic carbon flow in the Krycklan catchment. : Modelling with focus on the terrestrial forest ecosystem.

    University essay from KTH/Mark- och vattenteknik

    Author : Francisco Mieres Dinamarca; [2016]
    Keywords : Dissolved Organic Carbon; Modelling; Krycklan Catchment;

    Abstract : Dissolved Organic Carbon accounts for many different functions in the boreal forest ecosystem. It is the main vehicle for organic carbon transport from the litterfall to the forest soil profile and together with water drainage it can be transported to streams. READ MORE

  6. 20. 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.
