1. Atmospheric Chemistry of Volatile Organic Compounds: Oxidation Products, Mechanisms and Secondary Organic Aerosol Formation
Sammanfattning : The results from this work are a piece in understanding the complex puzzle of atmospheric aerosol formation. Secondary organic aerosol (SOA) formed by the oxidation of volatile organic compounds (VOC) in the atmosphere is a key component of air pollution with a strong negative impact on human health and influence on climate, but its formation is poorly understood.

2. Terpenes Emitted to Air from Forestry and the Forest Industry
Sammanfattning : A major environmental concern with respect to hydrocarbon emissions is the formation of phytotoxic photooxidants. The work reported in this thesis focusses on the poorly studied anthropogenic terpene emissions from the industrial use of softwood. LÄS MER
3. On the Extraction of Essential Oils by Supercritical Carbon Dioxide and its Influence on the Mesomorphic Phase Structures
Sammanfattning : A comparison of essential oils from leaves of Eucalyptus camaldulensis Dehn. obtained by hydrodistillation (HD) and supercritical carbon dioxide (SC-CO2) extraction is presented. Selected major components of the oils showed a predominance of higher molecular weight components in the SC-CO2 extracts than in those obtained by HD. LÄS MER
4. Biotransformations of Turpentine Constituents : Oxygenation and Esterification
Sammanfattning : This thesis describes methods to obtain valueaddedcompounds from TMP-turpentine obtained from the spruce, Piceaabies. The methodology focuses on biotransformations using twoapproaches: an oxygenation approach (i.e. oxygenation ofterpene hydrocarbons by cell cultures) and an esterificationapproach (i. LÄS MER
