1. Volatile metabolites from microorganisms in indoor environments : sampling, analysis and identification
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. 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. 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
4. Organophosphates and phthalates in air and dust from indoor environments : Method development and applied measurements
Sammanfattning : 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. LÄS MER
5. 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
