    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. 5. Organohalogen contaminants in Greenland shark (Somniosus microcephalus)

    Författare :Anna Strid; Åke Bergman; Maria Athanasiadou; Shinsuke Tanabe; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; persistent organic pollutants; sub-Arctic; Iceland; shark; Environmental chemistry; Miljökemi; miljökemi; Environmental Chemistry;

    Sammanfattning : The remote sub-Arctic/Arctic environment has due to human activities become a sink for organohalogen contaminants (OHCs). These OHC include traditional contaminants such as polychlorinated biphenyls (PCBs), DDTs and technical mixtures of polybrominated diphenyl ethers (PBDEs), all included in the Stockholm Convention list of persistent organic pollutants (POPs).
