[Health impact evaluation of particle air pollution in five Spanish cities. European APHEIS project].

Background: The health effects of air pollution have been analyzed in numerous studies over recent years, thus having made it possible to quantify the relationship between the two. This study is aimed at analyzing the theoretical benefits which would be achieved by meeting the air quality objectives set forth under EC Directive 1999/30/EC with regard to suspended particles.
