This study aims to analyze the short-term association between concentration of atmospheric pollutants and the mortality of elderly in the city of Curitiba (Brazil). The data comprised the period from 2003 to 2008. The relationships between the pollutants sulfur dioxide (SO2), ozone (O3) and total suspended particles (TSP) and the number of total deaths (ObT) and deaths due to respiratory deceases (ObR) of people aged over 60 years were investigated with simple correlation and multiple regression analyses, using a generalized additive model (GAM). The results showed a positive and statistically significant relationship between TSP concentrations and elderly mortality from all causes (ObT), even considering that TSP concentrations met the air quality standards during the period of study.
