  1. 16. Designing Mesoporous Test Sticks for Measuring PFAS Concentrations in Water

    University essay from Linköpings universitet/Nanostrukturerade material

    Author : Amanda Hillås; [2022]
    Keywords : Mesoporous material; PFAS; PFOA; PFOS; Rose Bengal; adsorption;

    Abstract : Water contamination through substances called per- and polyfluoroalkyl substances (PFAS) is a worldwide problem. Being able to measure the concentrations of PFAS in water is a first step towards beating this contamination. One alternative is to use a field test kit instead of extensive lab equipment to monitor the contaminated areas. READ MORE

  3. 17. Could fluorinated pharmaceuticals have an impact on the EOF amount in human blood?

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Tilda Alvén Fimmerstad; [2022]
    Keywords : ;

    Abstract : Recent studies have discovered an increasing amount of unknown organofluorine in human blood. This increase insinuate that humans might be exposed to potentially new and unidentified organofluorine compounds. READ MORE

  5. 19. GAC filter Design Criteria for Wastewater Treatment for Removal of Organic Micropollutants – A Literature Review

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Bhargav Reddy Elavarthi; [2021]
    Keywords : micropollutants; activated carbon filtration; empty bed contact time EBCT ; pharmaceuticals; breakthrough curves; adsorption; PFOS; carbon use; water and environmental engineering; Technology and Engineering;

    Abstract : Granular Activated Carbon (GAC) is nowadays suggested as a fourth (quaternary) treatment step at municipal wastewater treatment plants to remove certain chemicals and particularly organic micropollutants (OMPs). This work investigated the different factors that affect the performance of the GAC filter for the removal of micropollutants in a municipal wastewater treatment plant. READ MORE

  6. 20. Per- and polyfluoroalkyl substances (PFAS) and the effect on apoptosis in early porcine embryo development in vitro

    University essay from SLU/Dept. of Clinical Sciences

    Author : Anna Leclercq; [2021]
    Keywords : apoptosis; PFAS; PFOS; PFHxS; IVF; IVP; porcine; pig; embryo; TUNEL; reproduction;

    Abstract : The aim of this study was to evaluate the effects of PFHxS (perfluorohexane sulfonic acid) and PFOS (perfluorooctane sulfonic acid) on early embryo development parameters and apoptosis on day 6 post fertilization in porcine embryos. A second purpose was to evaluate, and establish, the TUNEL assay in our IVF laboratory. READ MORE
