  1. 1. Sorption of per- and polyfluoroalkyl substances (PFAS) in contaminated water using sustainable organic- and inorganic materials

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

    Författare :Natalie Storm; [2022]
    Nyckelord :Sorption | PFAS | Contaminated water | Bark | Steel slag | Biochar | Activated carbon;

    Sammanfattning : Per- and polyfluoroalkyl substances (PFAS) are a large group of anthropogenic compounds with unique properties, including chemical inertness, resistance to many degradation processes and amphiphilic structure. This makes them useful in a range of applications, but also very persistent and bioaccumulative in nature, where PFAS have been linked to adverse health effects in both animals and humans. LÄS MER

  3. 2. Spårmängdsanalys av explosivämnen

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Cheryl Loorents; [2020]
    Nyckelord :Spårmängdsanalys; explosivämnen; R-salt; TNT; PETN; LC-UV; SPE; LC-MS;

    Sammanfattning : There is an alarming increase of explosions with devastating consequences, the ultimate being loss of life. Furthermore, these kinds of substances have a toxic effect on animals, nature and humans if they are incorrectly disposed. LÄS MER

  4. 3. Identification of mycotoxins and glyphosate in human plasma

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

    Författare :Ida Markström; [2020]
    Nyckelord :;

    Sammanfattning : Type one diabetes (T1D) and islet autoimmunity (IA) in people with a genetically susceptibility for the diseases can be triggered by environmental factors. It is earlier showed that the diet can be one of the environmental factors as it has been indicated that a cereal rich diet can increase the risk of developing IA. LÄS MER

  5. 4. Conditioning of chromatographic systems prior to metabolomic studies : Investigation of the conditioning effect and the possibility to alter it

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för analytisk farmaceutisk kemi

    Författare :Jasmin Telo; [2017]
    Nyckelord :Analytical chemistry; metabolomics; metabonomics; conditioning; conditioning effect; UPLC; Q-TOF; HILIC; Protein precipitation; Liquid-liquid extraction;

    Sammanfattning : The conditioning effect in metabolomic studies is the phenomenon of initial variation of analytical results in the first 5-10 injections of a biological sample in chromatographic systems. The deviation manifests itself as a drift in retention time, peak area and in multivariate analysis. LÄS MER

  7. 5. Method Development in Mass Spectrometry-based Proteomics for Determination of Early Pregnancy in Dogs

    Master-uppsats, Uppsala universitet/Analytisk kemi

    Författare :Sebastian Lindersson; [2016]
    Nyckelord :mass spectrometry; proteomics; orbitrap; canine pregnancy; CRP;

    Sammanfattning : This project is concerned with method development in mass spectrometry (MS)-based proteomics in order to find putative biomarkers for early pregnancy ofdomesticated dogs. It is of importance for dog breeders to know whether the dogsbecome pregnant post-mating. LÄS MER
