  1. 21. Ventilation/Perfusion Matching and its Effect on Volatile Pharmacokinetics

    Författare :Moritz Andreas Kretzschmar; Anders Larsson; Jan Jakobsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anesthesia; Animal models in research; Mass spectrometry; Gas chromatography; MIGET; Ventilation-perfusion; Desflurane; Isoflurane; Bronchoconstriction; Anestesiologi och intensivvård; Anaesthesiology and Intensive Care;

    Sammanfattning : The mismatching of alveolar ventilation and perfusion (VA/Q) is the major determinant of impaired gas exchange. The gold standard for analyzing VA/Q distribution is the multiple inert gas elimination technique (MIGET), conventionally based on gas chromatography (GC), and, although simple in principle, a technically demanding procedure limiting its use.

  3. 22. Partitioning and persistence of volatile methylsiloxanes in aquatic environments

    Författare :Dimitrios Panagopoulos; Matthew MacLeod; Annika Jahnke; Amelie Kierkegaard; Whelan Mick; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; siloxanes; organic carbon; sediment; partitioning; persistence; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The presence of volatile methylsiloxanes (VMS) in the environment has raised concerns among environmental chemists and regulators about their persistence and the risks they may pose to the environment. This thesis explores the partitioning and persistence of VMS in aquatic environments. LÄS MER

  4. 23. Novel Technique for Analysing Volatile Compounds in Indoor Dust : Application of Gas Chromatography – UV Spectrometry to the Study of Building-Related Illness

    Författare :Anders Nilsson; Christer Tagesson; Verner Lagesson; Göran Strid; Linköpings universitet; []
    Nyckelord :acrylates adverse effects; air pollution; ultraviolet; indoor analysis; chromatography; gas; environmental exposure adverse effects; sick building syndrome etiology; dust; volatilization; Spectrophotometry; MEDICINE; MEDICIN;

    Sammanfattning : It is now generally acknowledged that particulate air pollution can cause respiratory symptoms and that indoor dust particles may be associated with mucous membrane irritation and odour annoyance. One reason for this may be that dust particles adsorb large quantities of gases and other volatile compounds. LÄS MER
