Why air in Milan is so polluted?
☀
Traffic today is responsible for about half of the production of nitrogen oxides (NOx) present in the atmosphere, while it contributes only 20 per cent to the fine particulate matter present in the air. The percentage drops to 1 per cent considering ammonia (NH3) as a pollutant. The attention of those who care about these issues should also focus on heating which contributes to 9 per cent of the production of nitrogen oxides (NOx) and for 56 per cent on the diffusion of fine particles, which are so often at the centre of debates when it comes to cars. Finally, it is agriculture that is responsible for 97 per cent of ammonia (NH3) emissions, which also causes the formation of secondary particulate, fine dust that is created directly in the atmosphere due to chemical reactions. Car manufacturers in recent years have made great strides as clearly emerges from the historical series on pollution in the city.
Che aria tira? - How's it hanging?

Through the theme of atmospheric pollution and specifically of fine dust, we carried an extended analysis that led all research groups to deal with specific datasets. With the help of tools for processing and displaying data, we decided to design and develop a magazine that would collect the research areas touched and the results obtained in an orderly and distinct way. The six chapters of which the magazine is composed give an extensive, current and factual overview of air quality in Milan.
Thank you !
