1. Modeling of ozone and nitrogen oxides pollutions in urban air environments
Kandidat-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionenSammanfattning : As the air quality in urban environments is a rising problem, a deeper understanding of how air pollution is dependent on different factors is necessary. In these environments, there are different parameters that effect how the chemical reactions of the pollutants are proceeding. LÄS MER
2. Atmospheric reactivity of cyclic ethers of relevance to biofuel combustion
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Biofuels are considered to be an environmental friendly alternative to fossil fuels as they have the potential to reduce the global emissions of greenhouse gases. Studies have showed that an increased use of ethanol could alter the atmospheric chemical composition and enhance urban ozone concentrations resulting in higher human mortality rates. LÄS MER
3. Biogenic volatile organic compound emissions from Willow trees
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : In August 2012, emissions of biogenic volatile organic compounds (BVOCs) from willow (Salix) trees were measured in Lund, southern Sweden. Sweden has more than 16000 ha of short rotation willow plantations for biofuel production and willow trees are suspected to emit substantial amounts of BVOC to the atmosphere. LÄS MER
4. Furan - A Future Fuel and its Lifetime in Urban Air
Kandidat-uppsats, Lunds universitet/Fysiska institutionenSammanfattning : With a rising global mean temperature caused by increased emission of greenhouse gases into the atmosphere biofuels are considered as a possible solution to the greenhouse effect. One of the potential biofuels is furans and this report aims to determine their lifetime in polluted air. LÄS MER
