다중이용시설에서의 PM10, PM2.5 및 부유세균의 측정

PM10, PM2.5 and floating bacterial measurement in multiplex use facility

  Recently, it are increasing the use of facilities of multiplex facility. Therefore, we investigated this experiment to know current situation of indoor air quality. We measured PM10 and PM2.5 and floating bacterial because it became an issue of indoor air quality. We measured in subway platform and passenger car, underground arcade, theater, coffee shop etc.. Results of measurements PM10, PM2.5 all demonstrated the highest numerical value at underground coffee shop, and ground coffee shop and underground arcade that exceeded preservation standard limit. And it went over 3 places of whole 15 places for PM10 standard. Also, it was discovered pass over floating bacterial results of measurements preservation test. And it showed that went over was 8 places of the whole 13 places for standard of 800 CFU/㎥. We recognized the situation of indoor air in multiplex use facilities through this experiments, and we should effort to improve indoor air quality of these facility.
