  1. 11. Multi-platform metabolomics assays to study the responsiveness of the human plasma and lung lavage metabolome

    Författare :Masoumeh Karimpour; Malin Nording L.; Magnus Åberg; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LC MS; GC MS; NMR; metabolomics; metabolite; exposure; postprandial; plasma; lung lavage; BW; BW; data analysis; univariate analysis; multivariate analysis;

    Sammanfattning : Metabolomics as a field has been used to track changes and perturbations in the human body by investigating metabolite profiles indicating the change of metabolite levels over time and in response to different challenges. In this thesis work, the main focus was on applying multiplatform-metabolomics to study the human metabolome following exposure to perturbations, such as diet (in the form of a challenge meal) and exhaust emissions (air pollution exposure in a controlled setting).

  3. 12. Hairdressers' occupational exposure to carcinogenic aromatic amines

    Författare :Gabriella Åkerman; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The hairdresser occupation is classified as probably carcinogenic to humans based on an excess risk for urinary bladder cancer, but it is unclear if current work as a hairdresser entails such a risk. The overall aim of this thesis was to investigate if hairdressers have an ongoing exposure to selected carcinogenic aromatic amines. LÄS MER

  4. 13. Chemical exposure in the work place : mental models of workers and experts

    Författare :Anita Pettersson-Strömbäck; Bengt Järvholm; Steven Nordin; Bo Strangert; Marianne Törner; Umeå universitet; []
    Nyckelord :self-assessment of exposure; predictions; expert judgment; risk; interpretation; time series analysis; MAPE; benzene; monoterpenes; styrene; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Sammanfattning : Many workers are daily exposed to chemical risks in their work place that has to be assessed and controlled. Due to exposure variability, repeated and random measurements should be conducted for valid estimates of the average exposure. LÄS MER

  5. 14. Occupational skin exposure to cobalt : origin and fate

    Författare :Jolinde Kettelarij; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Exposure to cobalt is not without risk. Besides adverse health effects on the respiratory system, cobalt is one of the most important sensitising metals with a contact allergy prevalence of 2.2% in the general population. Sources of exposure to cobalt in the general population are diffuse. LÄS MER

  7. 15. Metabolism and Biological Monitoring of Organic Acid Anhydrides

    Författare :Christian Lindh; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rats; human; distribution; analysis; biological monitoring; autoradiography; adducts; hemoglobin; plasma; urine; Hexahydrophthalic anhydride; methyltetrahydrophthalic anhydride; guinea pigs; Occupational health; industrial medicine; Yrkesmedicin; arbetsmiljömedicin;

    Sammanfattning : The aim of this thesis was to describe the metabolism and to develope methods for biological monitoring for two organic acid anhydrides (OAAs), namely hexahydrophthalic anhydride (HHPA) and methylhexa-hydrophthalic anhydride (MHHPA). The OAAs are reactive, low molecular weight chemicals used in vast quantities in the industry. LÄS MER
