Analysis of the Air Pollution Sources in the city of Rome (Italy)

Pollution depends on many natural and human factors. The variation of pollutant and weather changes modify the concentration of pollutant in time and space. In fact, this is not only a local problem, but a regional and even global influence is highlighted. People who moved from the countryside to the cities made the air condition worse, because of the factories activities and the domestic heating. These kinds of pollutants, together with the ones related to the urban traffic, are the base of the air toxicity, which can lead to a lot of health problems. Apart from people, even monuments and works of art can be damaged by pollution, especially in the city centres. Exposure to pollutants is usually higher in cities than in the countryside. The more common pollutants produced at high density urban areas are carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), ozone (O3), particulate matter (PM) and benzene (C6H6). The aim of this work is to study the air pollutant level in the city of Rome in order to analyse the emissions from di_erent sources. Furthermore, the pollutant exceeds of the limit of the Directive 2008/50/EC, the main legislation about ambient air quality, was analysed for the period taken into account.
