The research permitted to deep the scientific knowledge on the possible and potential risks to the health of the population as a result of daily exposure to pollutants, and to evaluate the possible protective role, or, conversely, aggravating, other factors, in relation to the biological damage from air pollutants in children.

CAMPAIGNS
to promote participation in the study carried out in schools was also an useful opportunity for discussion with teachers, parents and children for the study of environmental problems, not just those relating to air quality. Finally, the study could provide useful information option to guide interventions and policys aimed at protecting children's health from possible damage of air pollutants, both collectively and individually.
