Abstract
Maintaining high indoor air quality in hospitals is important for protecting the health of both personnel and patients. In this study, the results of air quality monitoring carried out in the intensive care unit of a hospital in Bolu, Turkey, are discussed. Air disinfection devices were used to reduce the concentrations of bacteria. A four-week sampling program was implemented. In the first and the last weeks of the sampling, the disinfection devices were turned off, while in the second and third weeks they were turned on. Bioaerosols were collected and their indoor levels were determined by counting all plate colonies and bacterial types were identified by MALDI-TOF-MS. The highest levels of bacteria were measured in the mornings and before the air disinfection devices were turned on. Doctors do their rounds at approximately 9-10 o’clock. The dominant bacteria in the air samples examined were Staphylococcus hominis, Micrococcus luteus, Staphylococcus capitis, Staphylococcus epidermidis, Corynebacterium afermentans, and Staphylococcus haemolyticus. The results showed that the air disinfection devices were effective in decreasing the concentration of microorganisms between 83.4%- 55% in the intensive care unit, which is very important for the healthcare staff and patients, especially during pandemics.
期刊介绍:
Journal of Environmental Engineering and Science is an international, peer-reviewed publication providing a forum for the dissemination of environmental research, encouraging interdisciplinary research collaboration to address environmental problems. It addresses all aspects of environmental engineering and applied environmental science, with the exception of noise, radiation and light.
