There are several well-known air pollution episodes occurring in Europe and in the United States during the 1940s and 1950s. Many studies have reported association between pollution levels and public health indicators, such as mortality, since the occurrence of those episodes. This study aims to investigate the association between daily mean concentration of atmospheric pollutants and the mortality among elderly people in Curitiba city. It has been verified the positive correlation between the concentration of atmospheric pollutants and the number of children hospitalizations in Curitiba city. The mortality data were obtained from Curitiba Health Department and the air quality data were obtained from Paraná State Environmental Institute. The air quality data are from two monitoring stations, located at the Ouvidor Pardinho Square and the Santa Casa Hospital. The data comprises the period from 2003 to 2008. A preliminary analysis of the air quality data revealed a significant amount of days without observations for some pollutants. From the preliminary analysis were selected, for correlation and multiple regression analyses, the following pollutants: total suspended particles, sulfur dioxide e ozone. The results indicated positive and statistically significant relationship between the total suspended particles levels and mortality among elderly people by all causes and by respiratory diseases. In relation to sulfur dioxide, one cannot say whether it is associated to the mortality among elderly people because, despite obtaining positive correlation and regression coefficients, the analysis did not yield statistically significant results. The ozone did not seem to be associated to the mortality among elderly people in Curitiba city. The main conclusion is that the concentration of total suspended particulates was associated to mortality among elderly people in Curitiba city, even with the observed concentrations meeting the legal standards imposed by legislation. The comments and conclusions are valid considering the study period of time (2003-2008).
