Abstract

To evaluate the possible influence of air pollutants on the incidence of respiratory tract neoplasm we studied 12 São Paulo City districts where air pollution is observed. We collected data on pollutants from 1981–1990 and correlated it with the incidence of larynx and lung neoplasms in 1997. Ozone was the pollutant that best correlated with the incidence of neoplasm. The correlation coefficients were 0.7234 (p = 0.277) and 0.9929 (p = 0.007) for lung and larynx cancer, respectively. There may be a relationship between air pollution and the incidence of respiratory tract neoplasm. This study, however, does not allow us to conclude that there is a causal relationship.
