1. Determination of benzene in urine and breath for monitoring of benzene exposure
Sammanfattning : The aim of this work was to develop and validate methods for determination of unmetabolized benzene in breath and urine. The methods were intended for the bio monitoring of benzene to assess both occupational and environmental exposure.A method was developed for the determination of benzene in end-exhaled air. LÄS MER
2. Alkylation of benzene/ethanol and toluene/methanol over ZSM-5
Sammanfattning : .... LÄS MER
3. Benzene-char conversion and particle-vapor characterization in biomass gasification
Sammanfattning : Biomass is increasingly attracting attention as an alternative to fossil fuels. Gasification permits the thermochemical conversion of biomass into a product gas rich in carbon monoxide and hydrogen. The product gas can be further processed to generate heat, electricity, synthesis gas, chemicals, and biofuels. LÄS MER
4. NMR studies of complex fluids and solids formed by surfactants
Sammanfattning : NMR methods have been designed and employed in studying ofcomplex liquids and solids formed by surfactants. PGSE NMRexperiments are easily biased by convection; this artifact canbe avoided by changing the sample holder and by usingconvection-compensated pulse sequences. LÄS MER
5. Health hazards and cancer in relation to occupational exposures among Swedish seafarers
Sammanfattning : This thesis explores health hazards for seafarers in the Swedish merchant fleet, and occupational risks for lung cancer, mesothelioma and hematologic malignancy (HM). A special focus has been exposure to benzene and biomarker levels for work on product or chemical tankers during the mid-1990’ies. LÄS MER
