Relatively to the pneumonia, 4.3% of inquired that it does not have generators in its habitations relate already to have had this problem of health whereas 6.4% of the inquired ones with generators in its residences affirm to have suffered from this disease. The reduced number of observed cases, in one and another category, does not allow in them to affirm that significant differences between a group exist statistical and another one. Data epidemiologists (Zeitoun, 2001) disclose that in So Paulo in Brazil, the atmospheric pollution is responsible for 15% of the hospital internments of children with pneumonia. Thus being, a percentile addition of 2,1% of pneumonias between the inquired ones with generators in its habitations, relatively to that it does not have them, can be explained by the increase of the atmospheric pollution in the interior of these same habitations. When inquired after symptoms of respiratory allergies, 30.4% of the inquired ones without generators affirm to possess them while 80.1% of the inquired ones with generators in its habitations affirm not to have them. The results of this inquiry, in the respeitante to this point, are compatible with possible resultant effect of atmospheric pollution of the use of generators for the domiciliria production of electricidade. Therefore that the great percentile difference between a group and another one, and the number of cases pointed in this study takes the one that the comparisons of averages for samples with equal variance, are statistical significant. The pointed problems of rinite in one and another one in case that (with generators and without generators) they are significantly identical corresponding 4.3% and 3.8% of the inquired ones, respectively. Here, the differences, although not significant statistical, they are not explained by effect of the resultant atmospheric pollution of the use of generators in the habitations. The asthma and bronchitis, the same have type of reply that the two previous ones, having been related this problem for 13% of the inquired ones without generators and for 9% of the individuals with generator.
