1. 1. Is two stage GAC better than one stage GAC for removing PFAS at a DWTP? : Investigation of PFAS removal from drinking water using two stage granular activated carbon (GAC) filter

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Oliver Ekesiöö; [2023]
   Keywords : GAC; PFAS; drinking water treatment; two stage GAC;

   Abstract : The removal of 34 per- and polyfluoroalkyl substances (PFAS) were compared in a 1 stagegranular activated carbon (GAC) filtration to a 2 stage GAC filtration in a pilot study at adrinking water treatment plant (DWTP). The PFASs that were present in the water wereperfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), perfluoropentanoic acid(PFPeA), perfluorohexanoic acid (PFHxA), perfluoroheptanoic acid (PFHpA), perfluorobutanesulfonic acid (PFBS), perfluoropentane sulfonic acid (PFPeS) and perfluorohexane sulfonic acid(PFHxS).

3. 2. Evaluation of per and polyfluoroalkyl substances (PFASs) and extractable organic fluorine (EOF) in composite wastewater samples from a hazardous waste management facility

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Felicia Johansson; [2020]
   Keywords : ;

   Abstract : Per- and polyfluoroalkyl substances (PFASs) have been used broadly in industries, firefighting foams, surfactant materials and consumer products. These compounds are very resistant to degradation in the environment and high exposure to these compounds may cause health issues such as cancer and immunosuppression. READ MORE

4. 3. Mechanism specific effects of two organic pollutants in a single and co-cultured system using two cell lines from Rainbow trout

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Nicole Stylin; [2020]
   Keywords : ;

   Abstract : The present project aims at the investigation of the toxic effects of two organic environmental compounds and to determine whether the interactions of the compounds are different in a single and co-cultured system using two cell lines. The two compounds used for this purpose were PFBS (perfluorobutanesulfonic acid) and BaP (benzo[a]pyrene). READ MORE

5. 4. Screening of per- and polyfluoroalkyl substances (PFASs) in drinking water in Sweden

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

   Author : Erik Gunnars; [2020]
   Keywords : PFASs; drinking water; per- and polyfluoroalkyl substances; persistent organic pollutants; PFOA; PFOS;

   Abstract : Worldwide use of per- and polyfluoroalkyl substances (PFASs), both legacy and past, are problematic due to their persistent nature. To date, PFASs are of high concern since they have been found not only in the environment but also in animals, plants and humans. READ MORE

6. 5. Per- and Polyfluoroalkyl Substances (PFASs) Removal from Landfill Leachate : Efficiency Evaluation in Column Experiments

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Emelie Johnson; [2019]
   Keywords : ;

   Abstract : Per- and polyfluoroalkyl substances (PFASs) are known for their wide spread in the environment, their persistent properties and their ability of biomagnification through the food chain. With properties such as oil and water repellence, temperature resistance and a long lifespan they have been frequently used in various areas, e.g. READ MORE
