Abstract(s)
The indoor air quality (IAQ) is essential for human comfort and
health. This study aimed at assessing physical, chemical and biological
parameters in the IAQ of an operating theatre. Particulate matter (PM) was
measured by the TSI optical particle sizer and physical and gaseous chemical
IAQ parameters were measured using the GrayWolf IQ610 probe. Airborne
microbial levels were evaluated by direct impaction to the culture media. The
lowest pollutants concentrations, bioaerosols and gaseous contaminants were
observed in surgery rooms and the highest in the transfer zone and
antechamber. The mechanical ventilation proved to be a determining factor on
the pollutant’s distribution. It was also found a strong correlation between PM
and bacteria (R2 = 0.81) and fungi (R2 = 0.95) levels. The relative humidity has
shown unfavourable levels to assure proper thermal comfort. Factors such as
cleaning frequency, occupancy rate and especially the HVAC system
significantly influenced the evaluated parameters.
