  1. 1. Temporal trends of Polybrominated diphenyl ethers (PBDE) and Hexabromocyclododecane (HBCDD) in Swedish Otter (Lutra lutra) and Grey Seals (Halichoerus grypus)

    Magister-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Kajsa Frost; [2023]
    Nyckelord :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;

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

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

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

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

    Sammanfattning : 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.

  4. 3. Validation of a Cleanup Method for Analysis of Novel Brominated Flame Retardants in Biota Matrices Sofie Björklund 2015-05-30 Supervisors Ingrid Ericson

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Sofie Björklund; [2015]
    Nyckelord :Novel Brominated Flame Retardants; cleanup method; multilayer silica column; biota matrices;

    Sammanfattning : Brominated flame retardants is a group of compounds present in numerous types of materials in our surroundings. Although their purpose is to slow the progression of a fire, many has been shown to be toxic to the environment. Novel brominated flame retardants have been introduced to the market as old ones have been removed. LÄS MER

  5. 4. Metodutveckling för analys av PBDE och HBCD i sediment

    Kandidat-uppsats, Sektionen för ekonomi och teknik (SET)

    Författare :Börje Sundvall; Linda Johansson; [2007]
    Nyckelord :PBDE; HBCD; bromerade flammskyddsmedel; sediment; extraktionsmetod;

    Sammanfattning : Brominated flame retardants (BFRs) has for many years been used in products to reduce their flammability, mainly in electronic products, textiles and construction materials. In 2003, Sweden imported 300 tons of brominated flame retardants. Leakage of these compounds has polluted natural environments. LÄS MER
