  1. 6. From emission sources to human tissues: modelling the exposure to per- and polyfluoroalkyl substances

    Författare :Melissa Ines Gomis; Ian Cousins; Robin Vestergren; Hermann Fromme; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PFAAs; PFOA; PFOS; fluorinated alternatives; human exposure; pharmacokinetic modelling; hazard assessment; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Produced since the 1950’s, per- and polyfluoroalkyl (PFASs) substances are persistent, bioaccumulative and toxic compounds that are ubiquitous in the environment. Being proteinophilic with a tendency to partition to protein-rich tissues, PFASs have been found in human serum worldwide and in wildlife with a predominance of long-chain perfluoroalkyl carboxilic acids (C7-C14 PFCAs) and perfluoroalkyl sulfonic acids (C6-C9 PFSAs).

  3. 7. Assessing environmental and contaminant stressors in a benthic amphipod

    Författare :Therese Jacobson; Brita Sundelin; Tamara Galloway; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multiple stressors; Reproduction; Temperature; Food; Parasites; Fenarimol; PFOS; TBT; Endocrine disruption; Ecdysteroids; Microsporidia; Microcosm; Crustacea; Amhipoda; Monoporeia affinis; Biology; Biologi; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Organisms in the aquatic environment encounter numerous stressors throughout their lifespan. Some of them are biotic such as food availability, predators and parasites. Others are abiotic and include shifting salinity and temperature change among others. LÄS MER

  4. 8. Influence of gut microbiota on xenobiotic toxicity in a Caenorhabditis elegans model with a focus on arsenic and PFAS

    Författare :Jagadish Mangu; Jana Jass; Abul Mandal; Nektarios Tavernarakis; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; C. elegans; physiological responses; gut microbe models; arse-nite; arsenate; PFAS; PFOS;

    Sammanfattning : Exposure to environmental toxins presents a hazard to humans. Inorganic metalloid- arsenic (As), organic chemicals- per and poly-fluoroalkyl substances (PFAS) are frequently detected in the environment. Exposure to As and PFAS is associated with multiple adverse effects in humans and animals. LÄS MER

  5. 9. Fate of perfluoroalkyl acids in the aquatic environment with a focus on mass balance studies

    Författare :Marko Filipovic; Urs Berger; Michael McLachlan; Crispin Halsall; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PFAA; PFOS; AFFF; tap water; ground water; WWTP; mass balance; atmospheric deposition; rivers; Baltic Sea; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Perfluoroalkyl substances (PFASs) are man-made chemicals. Their unique properties make them beneficial for a wide range of industrial and consumer product applications, such as in aqueous film forming foam (AFFF), durable water repellent clothing, hydraulic oils and food packaging materials.

  7. 10. Mass balance of perfluoroalkyl acids in the Baltic Sea

    Författare :Marko Filipovic; Urs Berger; Michael McLachlan; Bert Ove Lund; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PFOA; PFOS; mass balance; Baltic Sea; PFOA; PFOS; massbalans; Östersjön; miljökemi; Environmental Chemistry;

    Sammanfattning : Perfluoroalkyl acids (PFAAs) are man-made chemicals. Their unique properties make them beneficial for a wide range of industrial and consumer applications, such as constituents in fire fighting foams, hydraulic oils and food packaging materials. LÄS MER
