最近，许多采用低成本PM传感器的光学颗粒物（PM）监测仪已经在消费市场上可用。这些便携式低成本监测仪可用于表征PM浓度具有高空间和时间分辨率。本研究评估了四种低成本的PM监测仪（Speck, Dylos， TSI AirAssure和UB AirSense）与特性良好的参考仪器的性能，并研究了它们在PM现场暴露研究中的适用性。低成本监测器的特点是在一个房间大小的实验室室内，具有标准的相对湿度和温度条件，有两种PM来源：香烟烟雾和亚利桑那州测试粉尘。这项研究发现，所测试的任何监测仪在监测室内微环境中的空气质量方面都具有足够的精度，尽管需要用标准仪器对监测仪进行现场校准，以检测特定类型的颗粒。其他因素，如数据下载方法的灵活性；在为人体吸入暴露评估研究选择低成本PM监测仪时，还应考虑连通性、与环境条件的兼容性以及技术支持的质量。(C) 2016 Elsevier Ltd.版权所有。
Recently, a number of optical particulate matter (PM) monitors employing low-cost PM sensors have become available on the consumer market. These portable low-cost monitors can be used to characterize PM concentrations with high spatial and temporal resolution. This study evaluates the performance of four low-cost PM monitors (Speck, Dylos, TSI AirAssure, and UB AirSense) against well-characterized reference instruments, and studies their suitability for PM field exposure studies. The low-cost monitors were characterized in a room-sized laboratory chamber with standard relative humidity and temperature conditions, with two PM sources: cigarette smoke and Arizona Test Dust. This study found that any of the monitors tested perform with adequate precision for monitoring air quality in an indoor microenvironment, although the field calibration of the monitor with a standard instrument for specific types of particles would be required. Other factors such as flexibility in data download methods; connectivity, compatibility with environmental conditions, and quality of technical support should also be considered when selecting low-cost PM monitors for human inhalation exposure assessment studies.
