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 two-stage GAC filtration for PFAS reduction in drinking water

   University essay from SLU/Department of Molecular Sciences

   Author : Julia Söderberg; [2023]
   Keywords : Per- and polyfluoroalkyl substances PFAS ; Granular activated carbon GAC ; drinking water; removal efficiency; DWTP;

   Abstract : PFAS, or per- and polyfluoroalkyl substances, are a group of chemicals found in a wide range of industrial and consumer products. Due to their persistent nature and widespread use, concerns have been raised about their impact on human health and the environment. READ MORE

4. 3. The Role of Perfluoroalkyl Substances (PFAS) contaminated food for male infertility : A Scoping review

   University essay from Linnéuniversitetet/Institutionen för hälso- och vårdvetenskap (HV)

   Author : Tehseen Kamran; [2023]
   Keywords : Per-or polyfluoroalkyl substances; diet; food; male infertility;

   Abstract : Background: The trend of male infertility is increasing and it correlates with industrial development which has introduced various industrial contaminants in the environment and human life. PFASs are one of those contaminants. Humans are exposed to PFAS through various routes and sources, especially through food and diet. READ MORE

5. 4. Evaluation of selected parameters of Total Oxidisable Precursor Assay on per- and polyfluoroalkyl substances

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Sofia Francois; [2021]
   Keywords : Per- and polyfluoroalkyl substances PFASs ; Total oxidisable precursor TOP assay; solidphase extraction SPE ; washing steps; PFAS precursor compounds.;

   Abstract : Per- and polyfluoroalkyl substances (PFASs) are man-made fluorinated compounds that havebeen detected in humans, the environment, and wildlife. The strong C-F bonds contribute tothe high thermal stability of some PFASs and make them extremely resistant to degradationunder normal environmental conditions. READ MORE

6. 5. Modelling Competitive Sorption of Per- and Polyfluoroalkyl Substances (PFASs) to Soil and Sorbents

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Linnea Georgii; [2021]
   Keywords : PFAS; modelling; competitive sorption; adsorption; isotherms; PFAS; modellering; konkurrenseffekter; adsorption; isotermer;

   Abstract : Per- and polyfluoroalkyl substances (PFASs) have become contaminants of increasing concern to society due to the contamination of drinking water and the ecosystem. A better understanding of the sorption and transport of PFASs in soil systems is urgently needed, however there have been few studies dedicated to investigating competitive sorption among PFASs, and there is no available model to model such effects.
