Abstract

Background and Objectives: Wastewater contains various pathogens including viruses, BACTERIA, FUNGI, etc. These microorganisms can easily become airborne during normal operations of WASTEWATER TREATMENT PLANT and contaminate the neighborhood environment. The aim of this study was to investigate the type and density of bioaerosols in a PETROCHEMICAL WASTEWATER TREATMENT PLANT in Iran.Materials and Methods: In this cross sectional study, bioaerosols density was measured in different units of a PETROCHEMICAL WASTEWATER TREATMENT PLANT according to the NIOSH 0800 method and the values measured were compared with background level (control area). For this purpose, air samples were collected on blood agar and dextro agar in Andersen single-stage sampler with air flow of 28.3 lit/min for 10 minutes. Samples collected were shipped to the laboratory immediately and were incubated for 48 hours. Then, incubated samples were counted for colonies concentration.Results: Average concentration of BACTERIA and FUNGI bioaerosols measured were 731.70±185.49 and 28.43±10.58 (M±SD) CFU/m3 respectively throughout the WASTEWATER TREATMENT PLANT units. These values were 35 and 1.45 times higher than background level (Control area). The differences between average concentrations of BACTERIA in all units of WASTEWATER TREATMENT PLANT with control area were statistically significant.Conclusions: Generally, it was found that the density of bioaerosols, especially BACTERIA was much higher than the background level. The maximum density was measured at aeration chamber, where the emission of bioaerosols could be reduced through replacing nozzle diffused aeration system.
