  2. 1. Persistent organic pollutants in benthic foodwebs

    Author : Niklas Holmqvist; Biologiska institutionen; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Henrik Selin; Loftsson Elfar; Linköpings universitet; []
    Keywords : 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;

    Abstract : 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.

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

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

    Abstract : 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. READ MORE

  6. 4. Developmental neurotoxicity of persistent and non-persistent pollutants : Behavioral and neurochemical assessments of a perfluorinated compound, pesticides and interaction effects

    Author : Iwa Lee; Henrik Viberg; Per Eriksson; William Mundy; Uppsala universitet; []
    Keywords : Brain; Neonatal; Mixtures; Cholinergic system; Organochlorines; Pyrethroids; Organophosphates; Carbamates; Insecticides; PFCs; PFAAs; PFHxS; Endosulfan; Cypermethrin; Chlorpyrifos; Carbaryl; Biology with specialization in Environmental Toxicology; Biologi med inriktning mot miljötoxikologi;

    Abstract : The focus of this thesis was to investigate developmental neurotoxic effects of different persistent and non-persistent environmental pollutants, alone or in binary mixtures, when exposure occurs during a critical period of brain development, in mice. The compounds investigated included a perfluorinated compound, perfluorohexane sulphonate (PFHxS), and four different pesticides, endosulfan, cypermethrin, chlorpyrifos and carbaryl. READ MORE

  7. 5. Persistent halogenated pollutants in mothers´ milk

    Author : Johan Fång; Åke Bergman; Cathrine Thomsen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; miljökemi; Environmental Chemistry;

    Abstract : Persistent organic pollutants (POPs) are substances that degrade slowly, are distributed wotldwide, bioaccumulate and are harmful to both animals and humans. The release of POPs to the environment was the preamble to human background contamination. READ MORE
