A clean air supply is essential to our own health and that of the environment. But since the industrial revolution, the quality of the air we breathe has deteriorated considerably - mainly as a result of human activities. The issue of air quality is still a major concern for many European citizens. It is also one of the areas in which the European Union has been most active. Since the early 1970s, the EU has been working to improve air quality by controlling emissions of harmful substances into the atmosphere, improving fuel quality, and by integrating environmental protection requirements into the transport and energy sectors. Waspmote has been used to control public transportation and monitor environmental parameters in several cities in Serbia.
Italian National Institute of Statistics (ISTAT) presented an analysis of air quality in European cities for the 2004-2008 period using the European Environment Agency's (EEA) AirBase database. Elementary data from urban background stations were combined into a single indicator - the average number of times that legally-defined concentration limits were exceeded.
