Assessment of personal exposure to particulate matter with an aerodynamic diameter less than or 2.5 µm (PM2.5) is necessary to study the association between PM exposure and health risk. Development of a personal PM2.5 sensor or device is required for the evaluation of individual exposure level. In this study, we aimed to develop a small-sized, lightweight sensor with a global positioning system (GPS) attached that can measure PM2.5 and PM10 every second to assess continuous personal exposure levels. The participants in this study were apparently healthy housewives (n = 15) and university female teaching staff (n = 15) who live in a high PM2.5 area, Yangon, Myanmar. The average PM2.5 exposure levels during 24 h were 16.1 ± 10.0 µg/m in the housewives and 15.8 ± 4.0 µg/m in the university female teaching staff. The university female teaching staff showed high exposure concentrations during commuting hours, and had stable, relatively low concentrations at work, whereas the housewives showed short-term high exposure peaks due to differences in their lifestyles. This is the first study to show that a GPS-attached standalone PM2.5 and PM10 Sensor [PRO] can be successfully used for mobile sensing, easy use, continuous measurement, and rapid data analysis.
评估小于或等于 2.5 微米（PM2.5）的空气动力学直径的颗粒物（PM）个人暴露量对于研究 PM 暴露与健康风险之间的关系是必要的。为了评估个体暴露水平，需要开发个人 PM2.5 传感器或设备。在这项研究中，我们旨在开发一种带有全球定位系统（GPS）的小型、轻便传感器，该传感器可以每秒测量 PM2.5 和 PM10，以评估连续的个人暴露水平。本研究的参与者是居住在缅甸仰光高 PM2.5 地区的健康家庭主妇（n=15）和大学女教师（n=15）。家庭主妇的 24 小时平均 PM2.5 暴露水平为 16.1±10.0μg/m，大学女教师的暴露水平为 15.8±4.0μg/m。大学女教师在通勤时间显示出高暴露浓度，而在工作时则保持稳定、相对较低的浓度，而家庭主妇则由于生活方式的不同而显示出短期的高暴露峰值。这是第一项表明 GPS 附加的独立 PM2.5 和 PM10 传感器[PRO]可成功用于移动感应、易于使用、连续测量和快速数据分析的研究。
