  1. 1. Towards International Chemical Safety : Taking Action on Persistent Organic Pollutants

    Författare :Henrik Selin; Loftsson Elfar; Linköpings universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Convention on Long-Range Transboundary Air Pollution CLRTAP ; persistent organic pollutants POPs ; regime analysis; social learning; Miljö; Föroreningar; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : Persistent organic pollutants (POPs) have been subject to increased international ro-operation over that past decade. The first international effort to address POPs collectively as a distinet class of pollutants was made under the United Nations Economic Commission for Europe (UNECE) and within the framework of the Convention on Long-Range Transboundary Air Pollution (CLRTAP), which geographically covers North America, Europe and the region of the former Soviet Union.

  2. 2. Persistent organic pollutants in benthic foodwebs

    Författare :Niklas Holmqvist; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; limnologi; Marinbiologi; limnology; aquatic ecology; marine biology; Hydrobiology; Ekologi; Ecology; Intraspecific interactions; streams; nutrients; lakes; crayfish; eels; Persistent organic pollutants; Benthic foodwebs; akvatisk ekologi; Environmental chemistry; Miljökemi;

    Sammanfattning : Concentrations of persistent organic pollutants (POPs) in aquatic biota are dependent on several factors both on individual and on system level. Bioaccumulation of POPs in pelagic biota in lakes as well as fish in streams has been shown to be dependent on nutrient regime of the system. LÄS MER

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

    Författare :Jana Weiss; Åke Bergman; Janice Huwe; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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

  4. 4. Persistent Organic Pollutants and the Environment : A Chemometric Approach to the Study of Halogenated Aromatics

    Författare :Tomas Öberg; Bo Bergbäck; Bo Wiman; Jaakko Paasivirta; Högskolan i Kalmar; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi; Environmental Chemistry; Miljökemi;

    Sammanfattning : Concern is growing about the environmental and health effects of persistent organic pollutants (POPs), many of which are halogenated aromatic compunds. The research reported in this thesis focuses on factors determining their behaviour and release into the environment. LÄS MER

  5. 5. Dioxins and dioxin-like compounds in thermochemical conversion of biomass : formation, distribution and fingerprints

    Författare :Qiuju Gao; Stina Jansson; Bogdan Dlugogorski; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Polychlorinated dibenzo-p-dioxins; polychlorinated dibenzofurans; polychlorinated naphthalenes; PCDD; PCDF; PCN; persistent organic pollutants; torrefaction; pyrolysis;

    Sammanfattning : In the transition to a sustainable energy supply there is an increasing need to use biomass for replacement of fossil fuel. A key challenge is to utilize biomass conversion technologies in an environmentally sound manner. LÄS MER
