Influence Of Ozone Air Contamination On TheNumber Of Deaths Ascribed To RespiratoryCauses In Madrid (Spain) During 1990–1998

In this paper the influence of the air quality on the mortality associated with respiratory causes in the Madrid (Spain) area during 1990-1998 is analysed. Air pollutants and mortality show that during this period there were two different effects; periodic annual fluctuations plus a monotonic evolution. It has been found that the slope values and signs of the monotonic components are different for each pollutant and mortality ascribed to respiratory causes; negative for particles, SO2, and NOx and positive for the O3 concentration and mortality values. A casual relationship between the mortality ascribed to respiratory causes and ozone concentration during the 1900-1998 period has been found. The variation detected in the Ultraviolet Index and traffic in Madrid City during the 1990-1998 period is also considered
