  1. 1. Volatile metabolites from microorganisms in indoor environments : sampling, analysis and identification

    Författare :Anna-Lena Sunesson; Alvin Fox; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adsorbents; Analysis; Cultivation; Determination; Gas chromatography; Identification; Indicator substances; Indoor air; Mass spectrometry; Metabolites; Microbial volatile organic compounds; Optimization; Sampling; Sick buildings; Thermal desorption; Aspergillus versicolor; Cladosporium cladosporioides; Paecilomyces variotii; Pénicillium commune; Phialophora fastigiata; Streptomyces albidoflavus;

    Sammanfattning : Microorganisms are able to produce a wide variety of volatile organic compounds. This thesis deals with sampling, analysis and identification of such compounds, produced by microorganisms commonly found in buildings. LÄS MER

  2. 2. A Sociological Approach to Indoor Environment in Dwellings : Risk factors for Sick Building Syndrome (SBS) and Discomfort

    Författare :Karin Engvall; Dan Norbäck; Eva Sandstedt; Göran Strid; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Indoor environment; Questionnaire; Atopy; Building age; Indoor air quality; Sick building syndrome SBS ; Validation; Dwelling; Energy conservation; Mechanical ventilation; Building dampness; Building reconstruction; Wood heating; Electric heating; Heat pump; Thermal Insulation; Sealing; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Sammanfattning : The principal aim was to study selected aspects of indoor environment in dwellings and their association with symptoms compatible with the sick building syndrome (SBS). A validated questionnaire was developed specifically for residential indoor investigations, using sociological principles and test procedures. LÄS MER

  3. 3. Oxidation of terpenes in indoor environments : A study of influencing factors

    Författare :Linda Pommer; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Monoterpene; Ozone O3 ; Nitrogen dioxide NO2 ; Nitrogen oxide NO ; Relative humidity RH ; Modelling; Scrubber; Experimental design; Interaction; Volatile organic compounds VOC ; Sick buildings syndrome SBS ; Principal component analysis PCA ; Indoor air; Ventilation; Tenax TA; Sodium sulphite; Miljökemi; Environmental chemistry; Miljökemi; analytisk kemi; Analytical Chemistry;

    Sammanfattning : In this thesis the oxidation of monoterpenes by O3 and NO2 and factors that influenced the oxidation were studied. In the environment both ozone (O3) and nitrogen dioxide (NO2) are present as oxidising gases, which causes sampling artefacts when using Tenax TA as an adsorbent to sample organic compounds in the air.

  4. 4. The emergence and preservation of sick building syndrome : research challenges of a modern age disease

    Författare :Åke Thörn; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :quantitative methods; qualitative methods; sick building syndrome; multi-case study; building-related illness;

    Sammanfattning : Since the 1970ies, the sick building syndrome (SBS) has become a common health problem. It is usually defined as a state of ill health consisting of subjective symptoms from mucous membranes and skin, as well as of' general symptoms such as e.g. fatigue and headache. LÄS MER

  5. 5. Methodological aspects of unspecific building related symptoms research

    Författare :Bo Glas; Berndt Stenberg; Anna-Lena Sunesson; Erik Zimerson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sick building syndrome; SBS; exposure measurement; GC-MS; questionnaire; symptom; variability; PCA; PLS-DA; Occupational medicine; Yrkesmedicin;

    Sammanfattning : This thesis deals with methological issues in the study of chemical exposure and sick building syndrome (SBS). SBS is a combination of general, mucosal and skin symptoms that some people experience when staying in specific buildings. The aim was to find chemical patterns associated with SBS, but also to address methological problems in such study. LÄS MER
