  2. 1. Improved analytical methods for perfluoroalkyl acids (PFAAs) and their precursors – a focus on human dietary exposure

    Author : Shahid Ullah; Urs Berger; Tomas Alsberg; Michael McLachlan; Jonathan W. Martin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental Science; PFASs; PFAAs; PFOA; PFOS; Precursor; FOSA; PAPs; Method development; LC-MS; SPE; Dietary sample; Drinking water; Human exposure; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Per- and polyfluoroalkyl substances are a large group of global environmental contaminants. They can be divided into two sub-groups, 1) perfluoroalkyl acids (PFAAs) and 2) so called precursors, i.e. compounds that can potentially be transformed to form PFAAs. READ MORE

  4. 2. Assessing the longitudinal trend of POP concentrations in humans using high-throughput sample preparation methods developed for low-volume samples

    Author : Jordan Stubleski; Anna Kärrman; Samira Salihovic; Petr Kukucka; Jean-Francois Focant; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Longitudinal trends; human biomonitoring; POPs; PFASs; high-throughput solid phase extraction; high-resolution mass spectrometry; tandem mass spectrometry;

    Abstract : Human exposure to anthropogenic persistent organic pollutants (POPs) and their related effects on human health widely vary from person to person, making population-based risk assessment difficult.This thesis aimed to evaluate how individual changes and implemented re-strictions in POP production influenced human exposure.

  5. 3. Remediation of per- and polyfluoroalkyl substance-contaminated soil and groundwater, using electrokinetic and stabilisation methods

    Author : Georgios Niarchos; Fritjof Fagerlund; Anett Georgi; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PFAS; contamination; emerging contaminants; forever chemicals; pollution; soil; groundwater; remediation; electrokinetic; stabilisation; activated carbon;

    Abstract : Per- and polyfluoroalkyl substances, commonly known as PFAS, are emerging contaminants with a worldwide environmental distribution and a concerning (eco)toxicological profile. The omnipresence of PFAS in various environmental media poses risks to the quality of our drinking water sources. READ MORE

  6. 4. Fluorine mass balance in wildlife and consumer products : How much organofluorine are we missing?

    Author : Lara Schultes; Jonathan P. Benskin; Michael McLachlan; Jörg Feldmann; Elsie M. Sunderland; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PFASs; PFOS; fluorine mass balance; organofluorine; EOF; TF; wildlife; consumer products; combustion ion chromatography; high resolution mass spectrometry; suspect screening; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are a class of anthropogenic pollutants. Many PFASs are highly persistent and have been linked to adverse effects in humans. According to latest estimates, there are more than 4700 PFASs in global commerce, which poses immense challenges for environmental monitoring. READ MORE
