letter to the editor: applications air q model on estimate health effects exposure to air pollutants

epidemiologic studies in worldwide have measured increases in mortality and morbidity associated with air pollution (1-3). quantifying the effects of air pollution on the human health in urban area causes an increasingly critical component in policy discussion (4-6). air q model was proved to be a valid and reliable tool to predicts health effects related to criteria nbsp; pollutants (particulate matter (pm), ozone (o3), nitrogen dioxide (no2), sulfur dioxide (so2), and carbon monoxide (co)), determinate nbsp; the nbsp; potential short term effects of air pollution nbsp; and allows the examination of various scenarios in which emission rates of pollutants are varied (7,8). air q software provided by the who european centre for environment and health (eceh) (9). air q model is based on cohort studies and used to estimates of both attributable average reductions in life-span and numbers of mortality and morbidity associated with exposure to air pollution (10,11). applications
