Abstract

In this case study, the real-time bioaerosol monitors (RBMs) were applied in elementary school classrooms along with upper-room ultraviolet germicidal irradiation (UVGI) devices. The classrooms were operated in the UVGI setting and non-UVGI control setting. After the measurement lasting eight weeks, we found statistical significant lower concentrations of fluorescent bioaerosols at 0.5 µm in the UVGI classroom in perspectives of class sections, classrooms, and weather conditions. The differences between UVGI and control classrooms were larger when the fluorescent bioaerosol concentrations were higher. The results of this study indicate that the upper-room UVGI could disinfect the fluorescent bioaerosols at 0.5 µm in environment as classrooms.
