1. Biomarkers of aromatic isocyanates in exposed workers
Sammanfattning : The aromatic isocyanates, toluene diisocyanate (TDI) and methylenediphenyl diisocyanate (MDI), are used in the production of polyurethane (PUR) foams, paints, elastomers and glues. The use of isocyanates is increasing, and exposure to isocyanates is the most common cause of occupational asthma. LÄS MER
2. Protein adducts of hexahydrophthalic anhydride- chemical structures and biomarkers
Sammanfattning : Organic acid anhydrides (OAAs) are low molecular weight chemicals used in the industry for manufacturing of plastics such as epoxy resins. Exposure to these chemicals may lead to symptoms from the eyes and the respiratory tract in form of conjunctivitis, rhinitis and asthma. LÄS MER
3. DNA adductomics: Method development and integration in biological effect monitoring
Sammanfattning : Environmental omics can provide informative biomarkers for identifying pathologies or physiological responses to environmental change. Nucleic acid adductomics, one of the newest omics techniques, is particularly well suited for assessing exposure and effects of environmental contaminants because the technique can capture modifications at the (epi)genome level.

4. Biological and air monitoring of exposure to isocyanates
Sammanfattning : Exposure to isocyanates may induce disorders in the airways of workers. Therefore, application, development and validation of methods for exposure assessment is of great importance. LÄS MER
5. Biomarkers of internal exposure/dose : Methods to quantify adducts to protein and DNA by LC/MS studied with benzo[a]pyrene and isocyanates
Sammanfattning : This thesis focuses on methods for quantification by liquid chromatography/mass spectrometry (LC/MS) of specific biomarkers for internal dose of chemicals which induce toxicity through their electrophilic reactivity. In vivo such compounds are short-lived, and could feasibly be measured as their reaction products (adducts) with biomacromolecules. LÄS MER
