11. PFAS-föroreningar i råvatten. : En studie uppströms Borgs vattenverk
Kandidat-uppsats, Linköpings universitet/Tema MiljöförändringSammanfattning : Poly- och perfluorerade alkylsubstanser (PFAS) är syntetiskt tillverkade kemikalier som omfattar cirka 4700 individuella ämnen. PFAS har använts sedan 1950-talet i ett antal applikationer som brandsläckningsskum, impregneringsmedel samt textilier, på grund av sina unika egenskaper att vara både vattenlöslig (hydrofila) och vattenavstötande (hydrofoba).

12. Phytoremediation potential for poly- and perfluoroalkyl substances (PFASs) using various plant species
Master-uppsats, SLU/Dept. of Aquatic Sciences and AssessmentSammanfattning : Poly- and perfluoroalkyl substances (PFASs) have unique chemical characteristics and are used in a wide variety of products. PFASs have been found in wild animals and humans and have shown adverse effects. Different remediation methods have been developed to remediate PFASs in the environment. LÄS MER
13. Evaluation of selected parameters of Total Oxidisable Precursor Assay on per- and polyfluoroalkyl substances
Magister-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : 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. LÄS MER
14. Modelling Competitive Sorption of Per- and Polyfluoroalkyl Substances (PFASs) to Soil and Sorbents
Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : 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.

15. Översilningsytors potential att rena lakvatten från PFAS
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Poly- and perfluorinated alkyl substances (PFASs) is a group of more than 5000 different substances, of which all consist of a fluorinated carbon chain resulting in a strong bond. Most of these substances are shown to be persistent, bioaccumulative and toxic for both humans and the environment. LÄS MER
