Several studies have presented statistical association between air pollution levels and morbidity and/or mortality in populations. The most common outcomes regarded in these studies are respiratory, cardiovascular diseases and, lately, lung cancer. The aim of this work is to estimate the association between air pollution and lung cancer mortality among elderly people in Rio de Janeiro, from September 2000 to December 2001. An ecological time series approach was used. In order to adjust for confounders and estimate the effects of interest, semiparametric Poisson regression was applied. Statistically significant effects were found for carbon monoxide (CO) but not for the other pollutants analysed. The relative risks were 1.130 (1.000-1.276) and 1.232 (1.003-1.515) for three days lagged and cumulative seven days exposure to CO respectively.
