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

    Author : Anna-Lena Sunesson; Alvin Fox; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Aerosols of Isocyanates, Amines and Anhydrides : Sampling and Analysis

    Author : Jakob Dahlin; Gunnar Skarping; Robert P. Streicher; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; isocyanate; amine; aminoisocyanate; organic acid anhydride; denuder; impactor; impinger; air sampling; LC-MS; LC-CLND; di-n-butylamine; DBA; thermal degradation; aerosol; particles; TDI; MDI; HDI; ICA; MIC; IPDI; exposure; occupational health; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Abstract : This thesis presents methods for air sampling and determination of isocyanates, amines, aminoisocyanates and anhydrides. These organic compounds are generated during thermal degradation of polymers such as polyurethane (PUR) or epoxy.Isocyanates, amines and anhydrides are airway irritants known to cause occupational asthma.

  5. 3. Passive sampling of PAHs and some trace organic compounds in occupational and residential air: needs, evaluation and limits

    Author : Pernilla Bohlin; Göteborgs universitet; []
    Keywords : passive air sampling; PAH; POP; occupational environment; residential environment; exposure; stationary air sampling; personal air sampling; PUF; evaluation;

    Abstract : Human exposure to elevated levels of polycyclic aromatic hydrocarbons (PAHs) and trace organic compounds (e.g. PCB, OCP, PBDE) can be related to negative health effects. This raises demands of exposure measurements to be performed. READ MORE

  6. 4. Organophosphates and phthalates in air and dust from indoor environments : Method development and applied measurements

    Author : Caroline Bergh; Conny Östman; Peter Haglund; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organophosphate esters; phthalate esters; air; dust; sampling; method development; GC MS; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Abstract : Organophosphate and phthalate esters are polymer additives that are frequently found in air and dust in indoor environments. This thesis describes the development and application of air sampling and selective mass spectrometric (MS) determination of these two compound groups. READ MORE

  7. 5. Isocyanates, Amines and Alkanolamines : Sampling, Chromatography and Detection

    Author : Jakob B. Riddar; Marianne Dalene; Gunnar Skarping; Daniel Karlsson; Håkan Westberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Air-sampling; Isocyanates; Aromatic amines; Aliphatic amines; Alkanolamines; Hydrophilic Interaction Liquid Chromatography; Dry Denuder-Filter sampler; Liquid Chromatography–tandem Mass Spectrometry; Polyurethane Foam Extraction; Analytical Chemistry; analytisk kemi;

    Abstract : Isocyanates, aromatic-, aliphatic- and alkanolamines are commonly used in the industry today. Millions of workers in Europe are exposed. The most frequent health symptoms are respiratory and dermal disorder. Due to the health risk most of the compounds in this thesis are regulated by authorities and have occupational exposure limits (OELs). READ MORE
