| Popis: | BACKGROUND AND OBJECTIVE: EMECAM is a collaborative project that seeks to evaluate the short-term effects of air pollution on mortality in Spain. MATERIAL AND METHOD: We collected data for air pollutants (particles and gases), daily mortality (total except external, cardiovascular and respiratory causes) and co-variables (temperature, humidity, influenza and calendar variables) in 13 Spanish cities. The magnitude of the association in every city was estimated using GAM under a Poisson distribution. Combined estimates for each cause and pollutant were obtained under `fixed effects' and `random effects' models. RESULTS: An increase of 10 (g/m(3) in the levels of the average of the concurrent and one day lag for black smoke was associated with a 0.8% (Cl: 0.4-1.1) increase in mortality. The same increase in the concentration of SO2 was associated with a 0.5% (Cl: 0.1-1.0) increase in daily deaths, and a 0.6% (Cl; 0.3-0.8) increase in the case of NO2. An increase of 1 mg/m(3) in the levels of CO was associated with an increase of 1.5% (CI: 0.5-2.6) in daily deaths. CONCLUSIONS: There is a short-term association between increases of daily levels of air pollutants and the number of daily deaths in Spanish cities. Key words: Air pollution. Mortality.
