    Sammanfattning : Humans are continuously exposed to complex mixtures of anthropogenic chemicals. This thesis focus on human exposure to persistent organic pollutants (POPs). POPs ability to bioaccumulate and biomagnify together with the extensive historical use of POPs in e.g. LÄS MER

  3. 2. 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

    Sammanfattning : Chemical pollution is an increasing societal problem and has a major impact on human and environmental health. One important source of chemical pollution is plastic, which contains many different compounds with often largely unknown hazards. LÄS MER

  7. 5. Levels and sources of organophosphorus flame retardants and plasticizers in indoor and outdoor environments

    Författare :Anneli Marklund; Peter Haglund; Barbro Andersson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organophosphate esters; OPs; human exposure; air; dust; sewage treatment plants; sludge; oil; snow; deposition; flame retardants; plasticizers; analysis; TCEP; TPP; TCPP; TBP; TBEP; Environmental chemistry; Miljökemi;

    Sammanfattning : Global consumption of organophosphate esters (OPs), which are used as flame retardants and plasticizers, is rapidly increasing. Their use as additives in diverse applications poses a risk as they may be emitted from the products they are added to and be further transported in the environment. LÄS MER
