Analys av stadsluftens kvalitet med hjälp av geografiska informationssystem
Sammanfattning: The main purpose of this thesis is to look at in what different ways GIS, Geographic Information System, is used in the study of air pollution and also in the study of how air pollutions affect human health. Interest was focused on four different pollutions, because of their damage to humans. The background to why so many studies are conducted on the distribution of air pollution concentrations is the fact that they are a hazard to human health. Therefore governments and world organisations have put up guide lines on limiting concentrations. In Sweden there are 16-generation goals that have their finishing time in 2020. To be able to reach the goals by 2020 all 16 has a half way goal in 2010. GIS is an important tool in the work surrounding air pollution surveillance. It is a visualisation tool and a tool to perform different modelling. There have been improvements in the use of satellite data as a tool in surveillance of airborne pollutions. Studies conducted through this data use still needs ground measurements to compare with but not close to what is normally needed. This is also a less expensive way of studying air pollutions; the biggest flaw is that only the coarsest particles are detectable. Looking on the situation in Sweden in 2006, only four years until 2010, the prognoses are not looking optimistic for the four airborne pollutions studied in this thesis. Only the goal for sulphur dioxide is going to be reached. For the other three the way is still long.
