1. 1. Hur mycket organohalogener får vi egentligen i oss? En studie av total koncentration organohalogener i lax, sill och torsk : How much organohalogens do we really ingest? A study of total concentrations of organohalogens in salmon, herring, and cod

   Kandidat-uppsats, Linköpings universitet/Institutionen för tema

   Författare :Emma Hidbäck; Sofie Jansson; [2023]
   Nyckelord :organohalogens; organohalogener;

   Sammanfattning : Studies have shown high concentrations of organohalogens in lipid-rich foods, such as fish, which is believed to be the main source of human exposure to persistent organic pollutants (POPs) via food consumption. There are methods for measuring total organohalogens in, for example, water, but no standardized methods for food. LÄS MER

3. 2. Human Exposure to Per- and Polyfluoroalkyl : Substances through Fish Consumption

   Master-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

   Författare :Welmoed Nauta; [2023]
   Nyckelord :Per- and polyfluoroalkyl substances; Human exposure; Fish consumption; Glasbruket; Target analysis; Mass balance analysis;

   Sammanfattning : Human exposure to per- and poly-fluoroalkyl substances (PFAS) occurs mainly through two pathways, inhalation and ingestion. Dietary exposure to persistent organic pollutants (POPs), including PFAS, is driven mainly by the consumption of foods of marine or terrestrial animal origin. LÄS MER

4. 3. Maskot som kommunikativ strategi : En semiotisk analys av antropomorfa karaktärer på flingpaket

   Kandidat-uppsats, Malmö universitet/Institutionen för konst, kultur och kommunikation (K3)

   Författare :Olivia Persson; [2022]
   Nyckelord :Anthropomorphism; cereal packaging; mascot marketing; packaging design; representation.;

   Sammanfattning : This essay compares five breakfast cereal packages to study how they visually communicate to the audience through anthropomorphic mascots. The purpose of this study is to contribute with knowledge of how the use of anthropomorphic mascots can help a brand communicate. LÄS MER

5. 4. Tribolysis : – Reaction of Aromatic Halides for Potential Dehalogenation

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Sammanfattning : Out of the 17 Sustainable Development Goals (SDGs) adopted by the United Nations in 2015, chemicals and waste management are obtainable under six. Improper and unsafe disposal of toxic chemicals into the environment affects life below water (SDG 14), human health and well-being (SDG 7), and clean water and sanitation (SDG 6). LÄS MER

7. 5. 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

   Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

   Författare :Marichal Salameh; [2021]
   Nyckelord :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 ;

   Sammanfattning : 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. LÄS MER
