Rio de Janeiro is one of the most important Brazilian cities. Nevertheless, health effects of air pollutants on its population are scarcely known. This study was conduct to cover part of what is lacking on the subject. Air pollutants investigated were PM10, SO2, NO2, CO e O3 and the outcomes were emergency pediatric consultations due to respiratory complaints on 3 public health units, in Jacarepaguá, between April, 2002 and March 2003. Confounding variables were time trends, seasonality, temperature, humidity, rain volume and respiratory infections. Calendar effects (holidays and weekends) were also adjusted, There were several failures on pollutants monitoring, mainly SO2, which was not taken into consideration to this study, due to low amount of data. As determinants and clinical consequences of air pollutants are very different on upper or lower respiratory system, one of the articles estimated the association of air pollutants to ailments on both systems. Only O3 showed a positive and statistically significant result (although small), both related to emergency consultations due to respiratory complaints as to emergency consultations due to lower respiratory symptoms. Effect and exposure occurred on the same day. (lag0). On the second article, association between air pollutants and emergency consultations related to bronchic obstruction was studied. On this case, children were categorized in three groups, according to age. Only children under 2 years showed a strong, positive and statistically significant result with PM10. A similar effect was observed with O3, although with a boundary statistically significant (p<0,06). On this study, effect and exposure occurred on the same day, as well. Despite failures on monitoring, on both studies, environmental pollution parameters were related to an increased number of emergency pediatric consultations due to respiratory complaints in Jacarepaguá. During all period observed, monitored pollutants levels were under recommended limits.
