1. Analysis of PAHs and their transformations products in contaminated soil and remedial processes
Sammanfattning : Soil that is heavily contaminated with polycyclic aromatic hydrocarbons (PAHs) is often found at the sites of former gasworks and wood-impregnation plants. Since PAHs are toxic these sites represent a hazard to human health and the environment, and therefore they need to be treated, preferably by a method that destroys the contaminants, and thus eliminates the problem permanently.

2. Traffic related air pollution with emphasis on particle associated polycyclic aromatic hydrocarbons : Tire wear and biodiesel exhaust emissions
Sammanfattning : Particulate matter (PM) is regarded as one of the more important components of air pollution causing adverse health effects. A large group of compounds associated with PM are polycyclic aromatic compounds (PACs) which comprises polycyclic aromatic hydrocarbons (PAHs). LÄS MER
3. Chemical and bioanalytical characterisation of PAH-contaminated soils : identification, availability and mixture toxicity of AhR agonists
Sammanfattning : Contaminated soils are a worldwide problem. Polycyclic aromatic hydrocarbons (PAHs) are common contaminants in soil at former industrial areas, especially at old gasworks sites, gas stations and former wood impregnation facilities. LÄS MER
4. Particle emissions from residential wood and biodiesel combustion
Sammanfattning : Emissions from anthropogenic combustion sources, such as vehicles and biomass combustion, contribute significantly to ambient particulate matter (PM) both on a local and global scale. Exposure to ambient PM and air pollution in general is linked to a variety of different health effects and it has been estimated that as many as 2. LÄS MER
5. Polycyclic aromatic hydrocarbons : DNA damage and cell signaling
Sammanfattning : Oxidative stress is a threat to our wellbeing. The formation of reactive oxygen species may result in oxidative lesions in DNA and RNA. When challenging A549 cells with 18O-labeled hydrogen peroxide, we found that RNA was between 14-25 times more sensitive to [18O]-8-oxoGuo formation than [18O]-8-oxodGuo formation in DNA. LÄS MER
