  1. 41. Determination of benzene in urine and breath for monitoring of benzene exposure

    Författare :Göran Ljungkvist; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biological monitoring; benzene; breath; urine; dynamic headspace; membrane; gas chromatography; mass spectrometry; thermal desorption;

    Sammanfattning : The aim of this work was to develop and validate methods for determination of unmetabolized benzene in breath and urine. The methods were intended for the bio monitoring of benzene to assess both occupational and environmental exposure.A method was developed for the determination of benzene in end-exhaled air. LÄS MER

  3. 42. Exhaled markers of oxidative stress in the airways

    Författare :Mona Lärstad; Göteborgs universitet; []
    Nyckelord :exhaled air; exhaled breath condensate; malondialdehyde; 3-nitrotyrosine; ethane; pentane; isoprene; oxidative stress; airways; inflammation;

    Sammanfattning : Breath contains a number of different molecules, some of which may have potential use as markers for oxidative stress in the airways during chronic airway inflammation. The major objectives were to develop and validate methods for quantifying five potential exhaled markers of oxidative stress: malondialdehyde (MDA) and free 3-nitrotyrosine (3-NT) in exhaled breath condensate (EBC) and ethane, pentane and isoprene in exhaled air, and to test the applicability of the methods.

  4. 43. Organic solvents and cognitive functioning. With special reference to interaction with aging

    Författare :Linda Nordling Nilson; Göteborgs universitet; []
    Nyckelord :Solvents; occupational; neuropsychology; cognition; aging; chronic toxic encephalopathy; follow-up studies;

    Sammanfattning : The aim of the thesis was to study cognitive functioning in patients with chronic toxic encephalopathy (CTE) and in aging workers previously exposed to organic solvents. The discriminative power of a series of cognitive tests in identifying patients with CTE was examined. LÄS MER

  7. 45. Exhaled Nitric Oxide in epidemiological and experimental studies

    Författare :Anna-Carin Olin; Göteborgs universitet; []
    Nyckelord :Nitric oxide; exhaled air; nasal nitric oxide; ozone; pulp-mill; gassings; nitrate; ; atopy; sensitization; asthma; rhinitis; bronchiolitis;

    Sammanfattning : The overall purpose with this thesis has been to contribute to the assessment of theutility of exhaled nitric oxide (eNO) in epidemiological studies. The specific aims have been toinvestigate whether eNO increases after occupational exposure to high peaks of ozone, or afterexperimental exposure to ozone in ambient concentrations. LÄS MER
