  1. 21. Corrosion-included metal runoff from external constructions and its environmental interaction : a combined field and laboratory investigation of Zn, Cu, Cr and Ni for risk assessment

    Författare :Sofia Bertling; Inger Odnevall Wallinder; Herbert E. Allen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Atmospheric corrosion; metal runoff; metal dispersion; soil; limestone; retention; Miljöteknik; Environmental engineering; Miljöteknik;

    Sammanfattning : The 1990s has seen an increased awareness of possible environmental effects of corrosion-induced metal release from outdoor constructions. Considerable efforts have been initiated to perform critical assessments of possible risks of selected metals. Gaps of knowledge have been identified and research investigations started. LÄS MER

  3. 22. Fish bile in environmental analysis

    Författare :Margaretha Adolfsson-Erici; Michael McLachlan; Lillemor Asplund; Freek Ariese; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fish bile estrogenic triclosan rubber additives pulp and paper; Environmental chemistry; Miljökemi;

    Sammanfattning : This work explores the usefulness of fish bile analysis in combination with biomarkers for identifying and evaluating new environmental contaminants in the aquatic environment. It illustrates how bile analysis can be used together with biomarkers to assess the causes of estrogenic effects, to identify chemicals in the aquatic environment that are taken up by fish, and to monitor environmental exposure.

  4. 23. Development and comparison of in vitro toxicity methods for nanoparticles : Focus on lung cell exposure

    Författare :Siiri Latvala; Karine Elihn; Hanna Karlsson; Lennart Möller; Hannu Norppa; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Concerns for the toxic effects of airborne nanoparticles have been raised along with the increasing production of nanostructured materials. However, the health risks of nanoparticle exposure are currently not fully understood. The most commonly used techniques to study nanoparticle toxicity, both in vivo and in vitro, have several limitations. LÄS MER

  5. 24. Human exposure to perfluoroalkyl acids

    Författare :Robin Vestergren; Ian T. Cousins; Stuart Harrad; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Perfluoroalkyl carboxylic acids (PFCAs) and perfluoroalkane sulfonic acids (PFSAs) are persistent organic contaminants which have been globally measured in human serum samples at low μg L-1 concentrations. One hypothesis, the so-called "indirect hypothesis", postulates that exposure to precursor compounds is responsible for the presence of PFCAs and PFSAs in human serum. LÄS MER

  7. 25. Assessing human exposure to phthalates, alternative plasticizers and organophosphate esters

    Författare :Tuong Thuy Bui; Ian T. Cousins; Andrew Sweetman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Human exposure; phthalates; organophosphates; plasticizers; flame retardants; modelling; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Phthalate esters (PEs) and organophosphate esters (OPEs) are common indoor pollutants frequently detected in environmental (dust, air), personal (hand wipes, diet) and human matrices (urine, serum etc.). LÄS MER
