1. 1. Method development and screening of extractable organofluorine (EOF) and targeted PFAS analysis in food packaging materials

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Nora Larsson; [2022]
   Keywords : Per- and polyfluoroalkyl substances PFAS ; Food packaging materials; Extractable organofluorine; Method development; Combustion ion chromatography; Targeted analysis;

   Abstract : Per- and polyfluoroalkyl substances (PFAS) have been manufactured and used in differentapplications for several decades, including food packaging materials. During the last 20 yearsthese compounds have been acknowledged as hazardous for humans and the environment, anddifferent regulations on PFAS have been established on both national and international levels.

3. 2. Per- and Polyfluoroalkyl Substance (PFAS) Emissions from Recycling Processes of Lithium-Ion Batteries

   University essay from Uppsala universitet/Strukturkemi

   Author : Amanda Rensmo; [2022]
   Keywords : lithium-ion; battery; PFAS; recycling; LIB recycling; ion chromatography; hydrometallurgy; thermal processes; persistent;

   Abstract : The lithium-ion battery (LIB) recycling industry is currently under development to improve the yields for critical metals. However, the organic components of LIBs must also be handled, which may result in harmful chemical emissions as by-products. READ MORE

4. 3. A Comparative Analysis of Per- andPolyfluoroalkyl Substances (PFAS) and ExtractableOrganofluorine (EOF) Using Solid PhaseExtraction-Weak Anion Exchange and Ion PairExtraction in SerumMarichal SalamehSpring 2021Independent project

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Marichal Salameh; [2021]
   Keywords : Extractable organofluorine EOF ; Per- and polyfluoroalkyl substances PFAS ; horse serum; human serum; ion pair extraction IPE ; solid phase extraction - weak anion exchange SPE-WAX ; liquid chromatography tandem mass spectrometry LC-MS MS ; combustion ion chromatography CIC ;

   Abstract : Per- and polyfluorinated substances (PFAS) are compounds that consist of a carbon chainbackbone that is partially or entirely fluorinated, with an addition of a functional group. SomePFAS are known as persistent organic pollutants (POPs) and have therefore been drawing a lot ofattention as well as increased concerns. READ MORE

5. 4. Quantification of target per- and polyfluoroalkyl substances (PFASs) and extractable organic fluorine (EOF) in crayfish from Lake Vättern, Sweden.

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Wilma Villbrand; [2020]
   Keywords : ;

   Abstract : Per- and polyfluorinated substances (PFASs) are a family of persistent organic pollutants in which the aliphatic carbon chains have been fluorinated, either completely or partially. One subclass of PFASs are perfluoroalkyl acids (PFAAs), in which perfluoroalkyl carboxylic acids (PFCAs) and perfluoroalkyl sulfonic acids (PFSAs) are two prominent groups. READ MORE

6. 5. The study of organofluorine analysis applied to totaloxidizable precursor (TOP) assay to understand perandpolyfluoroalkyl substances (PFASs)

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Crystal Ho; [2018]
   Keywords : Poly- per-fluoroalkyl substances; total oxidizable precursor TOP assay; AFFFs; combustion ion chromatography; oxidation;

   Abstract : Per- and polyfluoroalkyl substances (PFASs) are synthetic chemicals which are used in a wide range of applications such as aqueous film forming foam (AFFF) for firefighting, paint, coating and cosmetics. For almost a decade, PFASs have received worldwide attention because of the ubiquitous detection of PFAS in the environment and their bioaccumulative, persistent and give toxic effects on animals and humans.
