World Health Organization (2011) : • Air pollution increases the risk of respiratory and heart disease in the population. • Both short and long term exposure to air pollutants have been associated to health impacts. • More severe impacts affect people who are already ill. Children, the elderly and poor people are more susceptible
WHO (2011) : What are the critical air pollutants today ? • There are significant health risks from population exposure to particulate matter (PM) and Ozone in many cities of developed and developing countries alike. • Other pollutants can be significant at hotpots (NO 2 , CO, …..)
European Environment Agency: Across the EU, PM 10 pollution causes approximately 375000 premature deaths per year EEA Technical report No 1/2009
WHO (2011) : The EU, average life expectancy is 8.6 months lower due to exposure to PM 2.5 produced by human activities.

Why is it important to better understand sources for air pollution in Lombardy? • Air pollution is known to pose severe health problems • The Po Plain is one of Europe ’ s most polluted areas (PM, Ozone, NO X ) • Limits set to protect the population are significantly exceeded
How did we estimate contributions from the most significant sources?
