1. 16. Perfluoroalkyl substances (PFASs), flame retardants and cyclic volatile methylsiloxanes in indoor air in Uppsala, Sweden : occurrence and human exposure assessment

   Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

   Författare :Bo Sha; [2017]
   Nyckelord :passive air sampling; SIPs; indoor air; PFAS; flame retardants; siloxanes; human exposure;

   Sammanfattning : Indoor air samples were collected from three buildings located at the Swedish University of Agricultural Science (SLU) campus in Ultuna, Uppsala, Sweden and from residences of nine volunteers working in the three buildings. Sorbent-impregnated polyurethane foam (SIP) disk passive air samplers were deployed in different types of rooms in the three buildings including computer room (n = 1), labs (n = 3), lecture rooms (n = 3), offices (n = 8) and dining areas (n = 3) and homes (n = 9) of the volunteers between September and November in 2016.

3. 17. Evaluation of bark material and granulated active carbon for treatment of perfluoroalkyl substances (PFASs) in wastewater

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Oskar Skoglund; [2017]
   Nyckelord :PFAS; WWTP; bark; GAC; flow; particle size; adsorption; COD; TOT-N; TSS; SPE; GFF; precursors.;

   Sammanfattning : Per- and polyfluoroalkyl substances (PFASs) are a group of artificial chemicals which have been used in a wide area of applications such as surface protection agents in cloths and different industrial applications. It has been found that PFASs are potentially toxic and are frequently found in the environment due to their persistent and mobile properties. LÄS MER

4. 18. Kommunal riskkommunikation om PFAS: Hantering och behov för långsiktiga miljö- och hälsorisker

   Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

   Författare :Emma Gustavsson; [2017]
   Nyckelord :public confidence; trust; risk perception; perspectives uncertainties; dependability; risk communication; PFASs; long-term risks; risk management; effective risk communication; Earth and Environmental Sciences; Medicine and Health Sciences; Social Sciences;

   Sammanfattning : Risk communication is an interactive process which aims to reduce public concerns about health- and environmental risks through gaining trust and confidence. PFASs (Polyfluoroalkyl and perfluoroalkyl substances) is more addressed today amongst Swedish municipalities because there are concern for surface- and groundwater pollution and concern about long-term health risks.

7. 20. Characterization of the metabolic changes in chicken liver due to exposure of perfluorooctane sulfonate (PFOS) during the embryo development

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

   Författare :Ayan Au Musse; [2017]
   Nyckelord :PFCs; PFOS; Lipidomics; Lipid metabolism; UHPLC Q-TOF-MS;

   Sammanfattning : Perfluoroalkyl substances (PFASs) are anthropogenic compounds that have been classed as persistent organic pollutants (POPs) and are found in both commercial and industrial products. PFASs have been detected in different environmental matrices and have been found to bioaccumulate in all trophic levels. LÄS MER
