Our objective was to combine these approaches and to analyze the relationship between perceived air quality and psychosomatic symptoms in adults and respiratory and allergic illnesses among schoolchildren and to screen for possible behavioral changes related to air quality. To achieve this, typical rural communities (without industrial sources) in the alpine area of Tyrol with contrasting amounts of traffic exposure were sampled and compared with respect to the objectives. Traffic flow through these valleys (20% heavy trucks) has quadrupled since 1970 and concern was raised about a deterioration of living quality in these residential areas.
