[AAS04-P17] Evaluation of a mobile PM2.5 sensor and application to the measurements along the National route 1 and around Nagasaki University
Keywords:Compact PM2.5 sensor , Personal exposure, Mobile measurement
In this study, we investigate the performance of the PM2.5 sensor for mobile exposure measurements. The changes in the sensitivity of the sensor during tilting or swinging have been tested. Moreover, the change in the sensitivity of the sensor during walking has been investigated, by comparing the PM2.5 data during walking with those during standing. From the results of these tests, it was found that the sensor can be applied for mobile exposure measurements of PM2.5 mass concentration. We applied this sensor for the mobile measurements during walking along the National Route 1 (from Tokyo to Kyoto) for two weeks, and around Nagasaki University. The obtained PM2.5 data will be compared with those obtained at the surrounding ambient air monitoring stations (AEROS) and meteorological data to discuss the sources and transportation of PM2.5. We believe that this research will provide useful information for applications of the compact sensor to epidemiological research of health effects of PM2.5.
