  4. 3. Microbial binding of per- and polyfluorinated alkyl substances (PFASs) : - Analysis of PFASs in microbes with ultra-performance liquid chromatography – tandem mass spectrometry (UPLC-MS/MS)

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Karolina Majdak; [2018]
    Keywords : PFASs; microbes; microbial binding; PFOS; PFHxS; AFFFs.;

    Abstract : Per- and polyfluorinated alkyl substances (PFASs) belong to a large group of man-made chemicals that pollute the environment. Perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) are the most commonly found PFASs. The pollution of PFASs can be caused among others by using of aqueous fire-fighting foams (AFFFs). READ MORE

  5. 4. Uptake of per- and polyfluoroalkyl substances by plants

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Laura Gobelius; [2016]
    Keywords : phytoremediation; Arlanda Airport; PFASs; groundwater; soil; plant; AFFF; aqueous fire fighting foams;

    Abstract : The extensive use of per- and polyfluoroalkyl substances (PFASs) as surfactants in, for example textiles,cookware and aqueous firefighting foams (AFFFs) during the last decades has resulted in widespread environmental contamination. Due to the persistent and bioaccumulative characteristics of PFASs, they are ubiquitously found in the environment, wildlife and humans. READ MORE

  6. 5. Transport of per- and polyfluoroalkyl substances in soil and groundwater in Uppsala, Sweden

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Sofia Bergström; [2014]
