Sammanfattning : Bioremediation of soils is considered a low-cost alternative to other remediation techniques. Its ability to remove a number of different pollutants has been demonstrated, relying mainly on the activities of indigenous soil bacteria. LÄS MER
2. Automation, hyphenation and multidimensional chromatography for PAH analysis : Analytical techniques to simplify sample complexity
Sammanfattning : One group of organic environmental pollutants which are potentially hazardous to human health is polycyclic aromatic hydrocarbons (PAHs). These compounds consist of two or more benzene rings in their structure among which benzo[a]pyrene (B[a]P) is classified as a human carcinogen. LÄS MER
3. Spatial variability linking carbon resource heterogeneity and microorganisms; causes and consequences
Sammanfattning : Organic carbon and bacteria have a high variability at different scales in the soil, and organic carbon may be a limiting factor for growth of soil bacteria. Thus, it can be expected that these co-vary at different scales in the soil. LÄS MER
Sammanfattning : Accidental fires represent a risk for people from the heat and fire effluents produced. It is clear from fire statistics that it is, in fact, the toxic gases that kill and injure many fire victims. Further, there are a number of compounds that are readily produced in fires, which have important sublethal effects on humans. LÄS MER
Sammanfattning : In order to theoretically study large and complex systems, a variety of approaches that can be categorized loosely as top-down or bottom-up are followed. While our vision is to bridge the gap between these approaches and use them together in multiscale materials modeling, the present thesis is limited to give examples of each type of approach in the study of soft-matter systems.
