Investigation about a possible correlation between the loading with environmental aerosols and the occurrence of child's lung disease

In the recent years the increase of respiratory diseases and allergies has been discussed extensively, both by experts and in the media, at the national and the international level. This rise of respiratory diseases and allergies has stimulated the search for potential causes. One of these presumed causes is the occurrence of environmental aerosols in ambient air. Within the framework of the present masters thesis it was attempted to correlate cause and effect for the city and province of Salzburg. For this purpose, aerosol measurements were carried out at a few selected places: Salzburg (Rudolfsplatz) as an urban area and Tamsweg and Hallein Winterstall as rural areas. A comparison of the results of these measurements between the three places indicates an unambiguous decrease of concentration of the particles in the air, from the city to the country side. This gradient in particle concentrations consistent with the frequency of respiratory diseases and allergies. It is therefore possible to suggest a relationship between the concentration of environmental aerosols in ambient air and the health effects considered in this study. However, I would like to point out that the results of the present masters thesis have some informative value, but it would still be necessary to confirm them by a greater number of measurements which were unfortunately not possible within the framework of the present work.
