1. Atmospheric Corrosion of Lead. The Influence of Organic acid Vapours and Inorganic Air Pollutants. A contribution Towards Understanding the Environmental Degradation of Historic Organ Pipes
Sammanfattning : This thesis presents different perspectives on the atmospheric corrosion of lead, aiming at a better understanding of the environmental degradation of historical organ pipes. Corroded organ pipes from the field have been analyzed and the environment inside the organ wind system has been mapped. LÄS MER
2. Lead in blood. ICP-MS studies of lead in plasma, blood and erythrocyte proteins
Sammanfattning : An inductively coupled plasma mass spectrometry (ICP-MS) method for the determination of lead in blood plasma has been developed. The detection limit was below 0.1 microgram/liter, and the precision 5%. There was no significant difference between levels in plasma and serum. LÄS MER
3. The fate of airborne lead pollution in boreal forest soils
Sammanfattning : Lead has a more than three-millennia-long pollution history in Europe. Metal production, burning of coal and use of leaded petrol resulted in a significant pollution of the atmosphere. As a consequence of atmospheric fallout, the Swedish boreal forest is strongly contaminated by airborne lead pollution. LÄS MER
4. Recyclable High Performance Thermosets from Biobased Rigid Building Blocks
Sammanfattning : The finite petroleum resources and increasing polymer waste have given rise to concerns associated with the origin and end of life management of polymer materials. Developing biobased and recyclable thermosets is an important and still underexplored part of this process, especially as thermosets also possess inherent recycling issues caused by their crosslinked structure.

5. Atmospheric Corrosion of Historic Lead Organ Pipes
Sammanfattning : The atmospheric corrosion of lead is investigated, with the aim to improve the understanding of the environmental degradation of historical organ pipes. Fieldwork is combined with laboratory investigations. The field studies included characterization of the organ environment and exposures of lead coupons. LÄS MER
