  1. 21. New approaches for synthesis and analysis of adducts to N-terminal valine in hemoglobin from isocyanates, aldehydes, methyl vinyl ketone and diepoxybutane

    Författare :Ronnie Davies; Margareta Törnqvist; Leif Kronberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbamoylation; modified-Edman procedure; 5- hydroxymethyl furfural; MISPE; biomarkers; Environmental chemistry; Miljökemi; miljökemi; Environmental Chemistry;

    Sammanfattning : Human exposure to harmful compounds in the environment, from intake via food, occupational exposures or other sources, could have health implications. Exposure to reactive compounds/metabolites can be identified and quantified as hemoglobin (Hb) adducts by mass spectrometry. LÄS MER

  3. 22. What contributes to human body burdens of phthalate esters? : An experimental approach

    Författare :Georgios Giovanoulis; Cynthia A. de Wit; Jörgen Magnér; Brice Appenzeller; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phthalates; Alternative plasticizers; DINCH; In vivo screening; Urine; Nails; Air; Dust; Hand wipes; Duplicate diet; Predictors of exposure; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Phthalate esters (PEs) and alternative plasticizers used as additives in numerous consumer products are continuously released into the environment leading to subsequent human exposure. The ubiquitous presence and potential adverse health effects (e.g. LÄS MER

  4. 23. Incorporation and preservation of geochemical fingerprints in peat archives

    Författare :Sophia V. Hansson; Richard Bindler; Dominik Weiss; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Peat; Beryllium; bulk density; C N-ratio; decomposition; deposition; downwash; elemental mobility; geochemistry; humification; lead; light transmission; mercury; peat accumulation; precipitation; Environmental Science; miljövetenskap;

    Sammanfattning : The present status of the environment, including environmental problems such as heavy metal accumulation in aquatic and terrestrial ecosystems, is in part the consequence of long-term changes. Cores from peatlands and other natural archives provide us with the potential to study aspects of the atmospheric cycling of elements, such as metal pollutants, on timescales much longer than the decade or two available to us with atmospheric deposition monitoring programs.

  5. 24. 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).

  7. 25. Chemical mixtures and interactions with detoxification mechanisms and biomarker responses in fish

    Författare :Johanna Gräns; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fish; AhR; CYP1A; PXR; Chemical mixtures; Chemical interaction; Biomarker;

    Sammanfattning : Several classes of anthropogenic chemicals are present as mixtures in the aquatic environment. However, information of how wildlife species, including fish, are affected by exposures to chemical mixtures is limited. LÄS MER
