  1. 1. Effect of PFOS and HBCD on the lipid profiles of developing rainbow trout (Onchorhynchus mykiss) analyzed with UHPLC/Q-TOF-MS

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

    Författare :Vanja Stefanovic; [2018]
    Nyckelord :Perfluorooctane sulfonate; hexabromocyclododecane; lipid metabolism; UHPLC Q-TOF-MS;

    Sammanfattning : Perfluorooctane sulfonate (PFOS) is widely used in industrial products and is potentially dangerous to the aquatic environment due to not being broken down whether by chemical or biological means, having a half-life of more than 41 years and disrupting hormones. Hexabromocyclododecane (HBCD) is the third most used brominated flame retardant and is of environmental concern as it bioaccumulates and magnifies in the food chain and is highly toxic to aquatic organisms.

  3. 2. Development and evaluation of methods for analysis of TBECH and HBCD using HRGC/HRMS and HPLC/MS/MS

    Magister-uppsats, Örebro universitet/Akademin för naturvetenskap och teknik

    Författare :Josefin Persson; [2009]
    Nyckelord :TBECH HBCD GC LC;

    Sammanfattning : The two additive brominated flame retardants, tetrabromoethylcyclohexane (TBECH) and hexabromocyclododecane (HBCD) are used to prevent fire to start and spread. They are simply mixed with material and are most likely to leach out in the environment, because of non-covalently binding to the material. LÄS MER

  4. 3. Dietary intake estimations of brominated flame retardants for Swedish children

    Magister-uppsats, Institutionen för livsvetenskaper

    Författare :Jonna Lindström; [2008]
    Nyckelord :Polybrominated diphenyl ethers PBDEs ; Hexabromocyclododecane HBCD ; Dietary intake; Children; Toxicology; Endocrine disruptor; Neurotoxicity; Sweden;

    Sammanfattning : The dietary intake of polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD) have been estimated for Swedish children. A dietary survey performed in 2003, including 4, 8-9 and 11-12 year olds, and concentrations in individual food items were combined. 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
