1. Ozone and diesel exhaust : airway signaling, inflammation and pollutant interactions
Sammanfattning : It is well established that air pollution has detrimental effects on both human health as well as the environment. Exposure to ozone and particulate matter pollution, is associated with an increase in cardiopulmonary mortality and morbidity. Asthmatics, elderly and children have been indicated as especially sensitive groups. LÄS MER
2. Cardiovascular effects of diesel exhaust : mechanistic and interventional studies
Sammanfattning : Background: Air pollution is associated with negative health effects. Exposure to combustion-derived particulate matter (PM) air pollution has been related to increased incidence of cardiovascular and respiratory morbidity and mortality, specifically in susceptible populations. Ambient particles, with a diameter of less than 2. LÄS MER
3. Polycyclic aromatic compounds (PAC) in diesel fuels and exhaust emissions : aspects of sampling techniques, chemical determination, multivariate data interpretation and PAC emissions reduction
Sammanfattning : The rapid growth in the number of motor vehicles has raised serious environmental health hazard problems in urban areas associated with vehicle exhaust emissions. Exhaust emissions from heavy duty diesel vehicles are very complex mixtures containing thousands of chemical components distributed between the particulate, semivolatile and gaseous phases. LÄS MER
4. Allergic airway disease : studies on diesel exhaust exposures, oxylipins and antioxidants
Sammanfattning : Allergic airway disease, i.e. allergic rhinitis (AR) and asthma, is a common health problem. The prevalence is increasing in most countries of the world. LÄS MER
5. Numerical Studies of Flow and AssociatedLosses in the Exhaust Port of a Diesel Engine
Sammanfattning : In the last decades, the focus of internal combustion engine development has moved towards more efficient and less pollutant engines. In a Diesel engine, approximately 30-40% of the energy provided by combustion is lost through the exhaust gases. The exhaust gases are hot and therefore rich of energy. LÄS MER
