Background and Aim: Indoor air quality is strongly influenced by outdoor air quality. Since most of the time people spend indoors and indoor air quality is of particular importance in therapeutic settings, this study aimed to determine the amount of pollutants in indoor and outdoor air of Tohid Hospital in Sanandaj.
Methods: This is a cross-sectional descriptive study. In this study, 120 of indoor and outdoor air samples were collected by TES-5200 copper counterpart machine from TES Taiwan. The concentration of particles in the mass state was calculated in µg/m3 and the particle contamination rate was calculated in particle size/m3. Particulate matter samples were collected from indoor and outdoor air. There were 9 stations in the hospital and 3 stations in each ward, and 3 stations were sampled from outside the hospital. Twice samples were taken from each station.
Results: According to the results of this study, the highest and lowest concentrations of particulate matter (PM2.5, PM4, PM7, PM10) were observed in the emergency room and the operating room, respectively. The highest level of contamination in terms of PM1 concentration was in the ICU ward. According to the analysis, there was no significant relationship between temperature and particle concentration as well as moisture and particle concentration for all sections studied. In this study, particulate matter was the most contaminated emergency department, and the best conditions were observed for the operating room ward.
Conclusion: The relationship between the amount of particles in the open air and the indoor air indicates the penetration of these particles from the outside into the building. And outdoor air can also affect indoor air quality.
