    Sammanfattning : The ever-increasing concern about the widespread occurrence of pharmaceutical substances in the aquatic environment has been recognized as an emerging environmental issue as it can cause undesirable effects on the ecosystem and human health. The current wastewater treatment methods are not designed to treat municipal wastewater from the contamination of various pharmaceutical substances. LÄS MER

  3. 2. 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

  4. 3. In vitro and in vivo oxidation of diastereomers of lignin models of arylgylcerol b-aryl ether type and heterologous expression of laccase

    Författare :Christina Bohlin; Leif Jönsson; Ming Tien; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Kemi; Chemistry;

    Sammanfattning : Enzymic and non-enzymic oxidation of lignin models of the arylglycerol β-aryl ether type was investigated in experiments aimed at providing a better understanding of the initial phase of biological lignin degradation. Product profiles and diasteromer selectivity were determined to gain knowledge of the properties of the oxidants and pave the way for evaluation of the presence of the oxidants in ligninolytic fungal cultures.

  5. 4. Mycotoxins in indoor environments. Determination using mass spectrometry

    Författare :Erica Bloom; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gas chromatography; Mass spectrometry; Mycotoxin; Indoor Air; Ergosterol.; Mold; High pressure liquid chromatography; Dust; Building materials;

    Sammanfattning : Dampness in indoor environments may cause various health problems. The specific causative agent(s) are unknown but may originate from degradation processes in damp materials, microbial growth, or a combination of these phenomena. The health impact of dampness in buildings is a politically, legally, and economically important question. LÄS MER

  7. 5. Fungal DNA, Mould, Dampness and Allergens in Schools and Day Care Centers and Respiratory Health

    Författare :Guihong Cai; Dan Norbäck; Christer Janson; Nils Åberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Day care centers; Quantitative PCR; Fungal DNA; Allergens; Indoor environment; Building dampness; Bacteria; Mycotoxins; Respiratory symptoms; Asthma; School environment; Viable moulds; School children; Occupational and Environmental Medicine; Arbets- och miljömedicin;

    Sammanfattning : Day care centers and schools are important environments for children, but few epidemiological studies exist from these environments. Mould, dampness, fungal DNA and allergens levels in these environments and respiratory health effects in school children were investigated in this thesis. LÄS MER
