  1. 1. Evaluation of two-stage GAC filtration for PFAS reduction in drinking water

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Julia Söderberg; [2023]
    Nyckelord :Per- and polyfluoroalkyl substances PFAS ; Granular activated carbon GAC ; drinking water; removal efficiency; DWTP;

    Sammanfattning : PFAS, or per- and polyfluoroalkyl substances, are a group of chemicals found in a wide range of industrial and consumer products. Due to their persistent nature and widespread use, concerns have been raised about their impact on human health and the environment. LÄS MER

    Sammanfattning : The growing concern around per- and polyfluoroalkyl substances (PFAS) and their negative health and environmental effects have lately become more apparent which also is reflected in the new, more strict regulations of permitted levels of PFAS in drinking water extracted from water resources. However, many point sources of PFAS pollution to the environment and to water resources are still not identified and assessed for risk. LÄS MER

  4. 3. Pharmaceuticals and other chemicals of emerging concern in leachate from a landfill and sludge storage facility

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Victoria Runnäs; [2022]
    Nyckelord :Chemicals of emerging concern CECs ; pharmaceuticals; leachate; landfill; sludge; wastewater treatment plant WWTP ; Potentiellt hälso- eller miljöfarliga kemikalier; läkemedel; lakvatten; deponi; slam; avloppsreningsverk;

    Sammanfattning : The occurrence of 86 chemicals of emerging concern (CECs) (including pharmaceuticals, parabens, per- and polyfluoroalkyl substances, pesticides, stimulants, an isoflavone and an industrial chemical) was investigated in this study at Hovgården, a waste facility in Uppsala (Sweden). The selected CECs were analysed using solid phase extraction, sludge extraction and ultra-high pressure liquid chromatography coupled to mass spectrometry. LÄS MER

  5. 4. Electrodialytic Remediation of PFAS-Contaminated Soil

    Master-uppsats, KTH/Vatten- och miljöteknik

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

    Sammanfattning : 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. LÄS MER
