Resumo
The purpose of this work was to investigate the bioaerosols reach emitted from aerators of the Sanitary Sewage Treatment in Araraquara, Brazil, using the coliform group as indicated microorganisms. The concentration of viable airborne coliforms was enumerated from various distances of the aerators using a one-stage impaction air collector in Chromocult Coliform Agar (MERCK), having as referential standard the counting gotten in other points of the city. Meteorological parameters were determined simultaneously with the bacteriological sampler. ANOVA was used as statistical method. The concentration of coliforms showed a significant difference in distances of up to 100 m from the aerators in relation to the referential standard. The meteorological parameters had not significant effect in the preservation of these microorganisms from 100 m of the emitting sources. The dispersion of bioaerosol from the aerators of the Station of Treatment of Sanitary Sewer of Araraquara is not source of contamination for areas that surround this station.
