    University essay from Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Author : Kajsa Frost; [2023]
    Keywords : Polybrominated diphenyl ether; PBDE; BDE; hexabromocyclododecane; HBCDD; Temporal trends; Flame retardants; Baltic grey seal; Halichoerus grypus; Eurasian otter; Lutra lutra; Intestinal ulcers; BDE-47; BDE-99; BDE-100; BDE-153; BDE-154; Earth and Environmental Sciences;

    Abstract : Polybrominated diphenyl ethers (PBDE) and hexabromocyclododecane (HBCDD) are brominated flame retardants. These compounds are lipophilic, persistent and have been shown to bioaccumulate. READ MORE

  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. Miljögifters påverkan på delfiners hälsa och överlevnad : individ och populationsnivå

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Elvira Palmborg; [2016]
    Keywords : delfiner; miljögifter; PCB; DDT; PBDE; HCH; PFC; PAH; kadmium; kvicksilver; dolphins; environmental contaminants; cadmium;

    Abstract : Delfiner är utsatta för många antropogena hot, där en av dessa är miljögifter. Bioackumulering och biomagnifiering uppstår ofta på grund av delfinernas höga position i näringskedjan och miljögifternas persistens, vilket resulterar i höga nivåer av föroreningar i späck. Detta kan i sin tur leda till olika toxiska effekter. READ MORE

  6. 5. Micro plastics in the oceans and their effect on the marine fauna

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Elin Andersson; [2014]
    Keywords : plastic; micro plastic; POPs; pollutants; additives; effects; animals; plast; miljögifter; tillsatser; effekter; djur;

    Abstract : Small pieces of plastic, termed “micro plastic” in the oceans derive mainly from degradation of big plastics such as beach littering, but also from sources of direct emission from e.g. beauty scrubbers and synthetic sand-blasting. These micro plastics are ingested by marine animals – mistaking them for plankton – or via prey. READ MORE
