The Research of the Airborne Microorganism Concentrations at the Specific Outdoor Sites of One Senior High School During Summer Period

Bioaerosols include allergens such as fungi, bacteria, actinomycetes, arthropods, and protozoa. When the particle size is small enough to pass through the respiratory tract entering the human body, the health of the local population is also threatened. Therefore, the purpose of this study attempted to understand the concentration of the airborne microorganism at special outdoor sites of one senior high school during summer period. The results indicated that total average bacterial concentration by using TSA medium incubated for 48 hr were 1.7times10³ cfu/m³, 1.7times10³ cfu/m³ and 5.5times10² cfu/m³ for sampling sites of A and C during summer period. In addition, total average fungi concentration by using MEA medium incubated for 96 hr were 3.3times10³ cfu/m³, 2.5times10³ cfu/m³ and 1.4times10³ cfu/m³ for sampling sites of A and C during summer period. Moreover, the high concentrations of bacteria and fungi were founded at sampling site A.
