1. Aerosols of Isocyanates, Amines and Anhydrides : Sampling and Analysis
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.

2. Isocyanates - methodology for gas and particle generation, sampling and detection
Abstract : Isocyanates are mainly used in the industry for the production of polyurethane (PUR) plastics. Workers are at risk of being exposed during the manufacturing of PUR. During thermal degradation of PUR, isocyanates are released and workers involved in hot work such as fire-fighting, welding etc. may also be exposed. READ MORE

3. Polyurethane - occupational exposure, biomarkers and symptoms
Abstract : Isocyanates may cause occupational asthma, rhinitis, and hypersensitivity pneumonitis. However, the mechanisms behind initiation of the disorders and the relations between exposure and effect are insufficiently elucidated. Means to biomonitor exposure and risk would be valuable.

4. Airborne Isocyanates, Aminoisocyanates and Amines
Abstract : Isocyanates are used in the production of polyurethane (PUR). Exposure to isocyanates is associated with respiratory disorders and may occur during production or processing of PUR. During thermal degradation of PUR, amines and aminoisocyanates are formed in addition to isocyanates. READ MORE

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