  1. 6. Tissue distribution studies and risk assessment of perfluoroalkylated and polyfluoroalkylated substances (PFASs)

    Författare :Daniel Borg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Perfluoroalkylated and polyfluoroalkylated substances (PFASs) represent a large class of man-made chemicals. These substances have emerged as environmental contaminants due to their extraordinary resistance to degradation, potential for bioaccumulation, toxicity and a global presence in humans, wildlife and the environment.

  4. 8. Binding of per- and polyfluoroalkyl substances (PFASs) in soil : effects of solution chemistry, soil properties, and PFAS structure

    Författare :Hugo de Campos Pereira; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The large environmental mobility and persistence of per- and polyfluoroalkyl substances (PFASs) along with confirmed or suspected toxicities make the substances one of the great challenges of our time in the fields of chemical management and environmental risk assessment. In order to risk assess PFAS-contaminated sites, improved quantitative and mechanistic understanding of the partitioning and retention in soil is crucial. LÄS MER

  5. 9. Treatment methods for the removal of per- and polyfluoroalkyl substances (PFASs) from drinking water : optimizing existing and exploring novel treatment techniques

    Författare :Vera Franke; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Worldwide, the demand for safe drinking water is rising. As drinking water sources are increasingly impacted by anthropogenic and environmental changes it is becoming a challenge to produce safe and clean water. LÄS MER

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

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

    Sammanfattning : 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.
