  4. 3. Local pollution and the risks of OPFR, PBDE and PFAS to the marine ecosystem outside Longyearbyen and Barentsburg in Svalbard

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Anna Olsson; [2016]
    Keywords : Local pollution; Organophosphorus flame retardants; Polybrominated diphenyl ethers; Perfluorinated alkylated substances; Sediment; Arctic; Svalbard; Adventfjorden; Grønfjorden; Risk analysis; Earth and Environmental Sciences;

    Abstract : Most of the ecotoxicological research conducted in the Arctic until today has focused on long range transport of pollutants, while fewer studies on local pollution have been published. The aim of this study was hence to investigate if local pollution of organophosphorus flame retardants (OPFRs), polybrominated diphenyl ethers (PBDEs) and perfluorinated alkylated substances (PFAS) occurs outside two settlements in Svalbard; Longyearbyen and Grønfjorden.

  5. 4. Method Development for Quantification of Different Persistent Organic Pollutants in Ringed Seal (Phoca hispida) from the Baltic Sea

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Amelie Nordström; [2016]
    Keywords : Ringed seal; Baltic Sea; Persistent Organic Pollutants; Sample pre-treatment;

    Abstract : Persistent organic pollutants such as polychlorinated biphenyls (PCBs), DDT and polybrominated diphenyl ethers (PBDEs) tend to accumulate in biota and are transferred through the aquatic food web, which result in a high accumulation in marine mammals. In recent years various novel flame retardants (nBFRs), which have replaced the banned PBDEs, have also started to occur in the environment. READ MORE

  6. 5. Dietary intake estimations of brominated flame retardants for Swedish children
