Abstract
Background and Objectives: Bioaerosols are related to a wide range of health effects including infectious and contagious diseases, acute toxic effects, allergies and even cancer. From this perspective, the hospital environment can cause secondary problems for the patients and hospital visitors. The purpose of this study is Survey of Fungi Bioaerosols with the approach of compare two passive and active sampling methods in ICU ward of Taleghani Hospital in Tehran.
Materials and Methods: This is a field - cross – sectional study; the sampling carried out by active and passive methods in two stages of the morning and afternoon and on the Sabrodextrose agar medium. Sampling height was in 120 cm above the floor, with flow 35.5 liters per minute and retention time of 10 minutes. In addition, the effect of environmental factors such as temperature and humidity were studied.
Results: in view of number of fungi colonies in different turns with passive sampling method, 75% of measurement places were in B level (clean level) of EU GMP standard (European Medicine Agency); and in compared to passive sampling method of bioaerosols, 80% of stations were in C level (medium) of EU GMP standard.
Conclusion: Results showed that sensitivity and precision of active sampling method in comparison with passive method, is higher. By comparing the results with the standards, more sampling stations was determined, in terms of the level of contamination, were in good and acceptable conditions and Small number of areas, need to have more proper ventilation. Ventilation using mechanical system can play an important role in improving the quality of the air in hospital environments.
