Abstract
Air pollution is a major environmental health problem especially in populated areas where road traffic is a contributing factor to bad air quality. Vehicle exhaust contains several species harmful to human health. Ozone is a secondary pollutant with precursors that partly originates from road traffic. It causes respiratory diseases and harms vegetation. High concentrations of surface ozone are considered one of the most serious air quality problems. The type of fuel used determines the mixture of exhaust compounds and affects the rate of which ozone is being produced in the atmosphere.

The aim of this project is to examine the impacts on the local air quality when introducing ethanol (E85) as the main fuel for cars in Malmö, Sweden.... (More)
Air pollution is a major environmental health problem especially in populated areas where road traffic is a contributing factor to bad air quality. Vehicle exhaust contains several species harmful to human health. Ozone is a secondary pollutant with precursors that partly originates from road traffic. It causes respiratory diseases and harms vegetation. High concentrations of surface ozone are considered one of the most serious air quality problems. The type of fuel used determines the mixture of exhaust compounds and affects the rate of which ozone is being produced in the atmosphere.

The aim of this project is to examine the impacts on the local air quality when introducing ethanol (E85) as the main fuel for cars in Malmö, Sweden. This is made by a literature study and by air pollution modeling. Real emission data is used and simulations are made for two different temperatures to represent both summer and winter conditions. It was found that E85 may increase the concentration of surface ozone and could thereby increase the health impacts due to road traffic related air pollution. The simulation result showed a significant increase in ozone concentration when using E85 as fuel because of the large amount of volatile organic compounds emitted, especially at winter conditions.
