1. Passive sampling of PAHs and some trace organic compounds in occupational and residential air: needs, evaluation and limits
Sammanfattning : 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. LÄS MER
2. Aerosols of Isocyanates, Amines and Anhydrides : Sampling and Analysis
Sammanfattning : 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.

3. Isocyanates, Amines and Alkanolamines : Sampling, Chromatography and Detection
Sammanfattning : 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). LÄS MER
4. New methods for determination of airborne pollutants : Focus on tetrabromobisphenol A, organophosphate triesters and polycyclic aromatic hydrocarbons
Sammanfattning : The work presented in this thesis concerns the development and evaluation of new methods of sampling and analysis of organic pollutants in the indoor and outdoor environment. In Paper I, the development of a new method was reported for the determination of the brominated flame retardant tetrabromobisphenol A (TBBPA) in air using sampling with glass fiber filter and polyurethane foam (PUF), ultrasonic solvent extraction and liquid chromatography coupled to electrospray ionisation mass spectrometry (LC-ESI/MS).

5. Resin acids in commercial products and the work environment of Swedish wood pellets production : Analytical methodology, occurrence and exposure
Sammanfattning : The aims of the work this thesis is based upon were to develop convenient analytical procedures for determining resin acids in biological and environmental matrices, and apply them to enhance understanding of the occurrence, exposure to and uptake by exposed individuals of resin acids. Particular focus has been on the workplace environment of the Swedish wood pellets industry. LÄS MER
