  3. 2. Förekomst av PFAS i kosmetiska produkter

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Carl Henricsson; [2017]
    Nyckelord :PFAS; perfluorinated alkylated substances; polyfluorinated alkylated substances; cosmetic products; trade organizations; European Union; legislation; Earth and Environmental Sciences;

    Sammanfattning : Poly- or perfluorinated alkylated substances (PFAS) have characteristics of being temperature resistant and film-forming as well as being both water-, dirt and fatretardant. These substances are used both industrially and in consumer products like cosmetics, simultaneously the detected levels of PFAS are rising in the Swedish environment and there is concern since several PFAS are toxic, bioaccumulative and very persistent to degradation in the environment.

  4. 3. Long-range Transport of Per- and Polyfluorinated Substances to Sweden : The Exposure in Mountain Grazing Reindeers

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

    Författare :Malin Johansson; [2016]
    Nyckelord :PFAAs; PFASs; UPLC-MS MS; reindeers; long-range transport;

    Sammanfattning : The aim of this study was to examine if perfluorinated alkylated substances (PFASs) reaches north of Sweden by long-range atmospheric transport. This was done by monitoring the levels of PFASs in reindeer livers at two locations in 2002 and 2010, respectively. LÄS MER
