    Sammanfattning : This thesis is focused on studies on the environmental fate and methodological improvements for determination of the global contaminants, PCBs and DDTs, and locally discharged phenolics, e.g. 4,5,6-trichloroguaiacol (4,5,6-TCG), and their transformation products. LÄS MER

  4. 23. Occupational exposure to brominated flame retardants : With emphasis on polybrominated diphenyl ethers

    Författare :Kaj Thuresson; Åke Bergman; Peter Fürst; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; occupational exposure; Brominated flame retardants; polybrominated diphenyl ethers; air and serum concentrations; decabromodiphenyl ether; Environmental chemistry; Miljökemi;

    Sammanfattning : Brominated flame retardants (BFRs) are a diverse group of chemicals, which are used to slow down or inhibit the development of fires. BFRs are incorporated into a wide range of consumer products that are considered as potential fire hazards, such as TV-sets, household appliances, computers, and textiles. LÄS MER

  5. 24. Pressurized Fluid Extraction : A Sustainable Technique with Added Values

    Författare :Monica Waldebäck; Karin Markides; Åke Bergman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; ASE; biomass; green chemistry; household waste; lipid; pesticide; PFE; pressurized fluid extraction; sediment; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Sammanfattning : The challenge for the future was defined by the Brundtland Commission (1987) and by the Rio Declaration (1992), in which the fundamental principles for achieving a sustainable development were provided. Sustainable chemistry can be defined as the contribution of chemistry to the implementation of the Rio Declaration. LÄS MER

  7. 25. Human exposure to persistent organic pollutants : Illustrated by four case studies in Europe

    Författare :Jana Weiss; Åke Bergman; Janice Huwe; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Human exposure; Persistent organic pollutants POPs ; Environmental chemistry; Miljökemi;

    Sammanfattning : An extensive use of chemicals in countless consumer products has resulted in human exposure to several persistent organic pollutants (POPs). Sufficient knowledge about their chemical composition properties and environmental faith is required, to be able to proper risk assess and regulate the substances. LÄS MER
