  1. 1. The contribution of 11 measurable Per- and Polyfluoroalkyl substances (PFAS) in extractable organofluorine in Swedish blood samples: a case study

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Daniela Ferrer Esquivel; [2019]
    Nyckelord :;

    Sammanfattning : Recent studies have shown increasing levels of unidentified fluorinated compounds, with unknown toxic effects to living organisms. These unidentified fluorinated compounds might be those novel replacements for PFOS and PFOA and some other related chemicals. LÄS MER

  2. 2. Sorption of perfluorinated and polyfluorinated alkylated substances (PFASs) in the subsurface of an industrial site in Sweden

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Carl Sköld; [2019]
    Nyckelord :Sorption; soil-water partitioning; Kd; PFOS; PFOA; PFHxS; Sorption; fördelningskoefficient; Kd; PFOS; PFOA; PFHxS;

    Sammanfattning : Per- and polyfluoroalkyl substances (PFASs) are a group of emerging chemicals which havereceived increasing attention due to their toxicity, persistent properties, and global distribution.In this study, sorption coefficients (Kd and KOC) of PFASs in an industrial site in Sweden wereevaluated.

  4. 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

  5. 5. Suspect screening of human serum with UHPLC-QTOF/MS

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Louise P. Poolsri; [2018]
    Nyckelord :;

    Sammanfattning : The number of environmental pollutants has increased due to the increased production and the use of various chemicals in different applications. An estimation of today’s synthetic chemicals is approximately 50,000 to 100,000 and many of them may be harmful to humans and the environment. LÄS MER
