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

摘要

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 research that used sampler is the Andersen six-stage viable sampler and the mediums which used in this study are tryptic soy agar (TSA) and malt extract agar (MEA). The results indicated that total average bacterial concentration by using TSA medium incubated for 48 hr were 1.7 X103 cfu/m3, 9.2 X102 cfu/m3 and 4.2 X103 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 13X103 cfu/m3, 1.6X103 cfu/m3 and 2.5 X 103 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 C.
