In this study, we aimed to compare fungal aerosols in terms of distribution in the ambient air of Milad Hospital, Blood Transfusion Organization, and Shahrake Ghods Waste Water Treatment Plant in Tehran, Iran. Methods: This cross-sectional study was conducted in Milad Hospital, Blood Transfusion Organization, and Shahrake Ghods Waste Water Treatment Plant within a period of four months. Passive sampling technique was applied every six days for one hour. Sabouraud dextrose agar was used as the culture medium. Results: Based on the comparison of the selected units, the highest level of fungal contamination was reported within a 100 meter distance from the last waste water treatment unit (67 CFU), while the lowest level of contamination was reported in Milad Hospital (30 CFU). Cladosporium was the dominant fungal genus in Shahrake Ghods Waste Water Treatment Plant and Blood Transfusion Organization (49% and 84%, respectively), while Alternaria was the most common fungus in the ambient air of Milad Hospital (47%). Conclusion: According to the results, processing and operating units in waste water treatment plants can affect the concentration and distribution of bioaerosols. Therefore, administrative organizations are required to take effective measures to develop guidelines and standards related to bioaerosols. Also, following environmental health norms in waste water treatment plants can be an important factor in reducing aerosol distribution.
