Chemical Characterization of the Indoor Air Quality of a University Hospital: Penetration of Outdoor Air Pollutants

Abstract: For healthcare centers, local outdoor sources of air pollution represent a potential threat to indoor air quality (IAQ). The aim of this study was to study the impact of local outdoor sources of air pollution on the IAQ of a university hospital. IAQ was characterized at thirteen indoor and two outdoor locations and source samples were collected from a helicopter and an emergency power supply. Volatile organic compounds (VOC), acrolein, formaldehyde, nitrogen dioxide (NO2), respirable particulate matter (PM-4.0… Show more

“…The above-mentioned evaluation approach of outdoor CCs concentration has been adopted to estimate the influence of outdoor pollution sources on indoor air quality by Scheepers, with sampling points inside and outside a hospital outer limits [53]. For healthcare center, outdoor sources of air pollution represent a potential threat to indoor air quality.…”

“…However, for FA these instruments have many limitations for the use in anatomy and pathology setting due the cross sensitivity with other organic compounds. False positive response may occur due to methanol which is a constituent of formalin or due to ethanol and isopropyl alcohol used in healthcare facilities for skin and surface disinfection [ 20 ]. In our study we used the DNPH method for air measurements with both 8 h and 15 min timeframes.…”

“…This method also has its limitations but in active sampling it is possible to reach a sufficiently low sensitivity and good precision. Problems with high air humidity can occur [ 20 , 21 , 22 ] but is not a problem in indoor settings.…”

“…For this reason, the quality of indoor air is greatly influenced by the respective outdoor quality value. Sources outside the building include air pollution, emissions from heavy traffic, parking areas, or activities such as industrial processes [23,24,25].…”
