这篇评论汇编了个人和室内微环境颗粒物（PM）监测需求，从最近设定的研究目标，最重要的是NRC出版的“研究重点空气中的颗粒物（1998年）”。技术和设备用于监测PM个人暴露和微环境浓度和成分的采样PM在过去的20年中，然后进行审查。为个人和微环境PM采样器和监测器、过滤材料以及用于设备校准、过滤器称重和实验室气候控制的分析实验室技术设定并讨论了发展目标。（电池供电）具有数据记录能力的监视器，用于存储微环境或活动相关传感器数据，先进的流量控制和浓度的连续记录。最好的过滤器是不吸湿的，化学纯的和惰性的，物理上坚固耐用，不受机械磨损。半自动和一级标准等效容积式流量计正在取代流量校准中精度较低的方法，而且个人采样流量应成为质量流量控制（有或没有压力和温度变化的体积补偿）。在称重实验室中，替代方案是气候控制（设定温度和相对湿度），以及机械上更简单的恒温、空调和恒温系统，结合对流量校准和过滤器称重的温度、湿度和压力影响的数字控制。(C)2002爱思唯尔科技有限公司版权所有。
This review compiles personal and indoor microenvironment particulate matter (PM) monitoring needs from recently set research objectives, most importantly the NRC published "Research Priorities for Airborne Particulate Matter (1998)". Techniques and equipment used to monitor PM personal exposures and microenvironment concentrations and the constituents of the sampled PM during the last 20 years are then reviewed. Development objectives are set and discussed for personal and microenvironment PM samplers and monitors, for filter materials, and analytical laboratory techniques for equipment calibration, filter weighing and laboratory climate control.The progress is leading towards smaller sample flows, lighter, silent, independent (battery powered) monitors with data logging capacity to store microenvironment or activity relevant sensor data, advanced flow controls and continuous recording of the concentration. The best filters are non-hygroscopic, chemically pure and inert, and physically robust against mechanical wear. Semiautomatic and primary standard equivalent positive displacement flow meters are replacing the less accurate methods in flow calibration, and also personal sampling flow rates should become mass flow controlled (with or without volumetric compensation for pressure and temperature changes). In the weighing laboratory the alternatives are climatic control (set temperature and relative humidity), and mechanically simpler thermostatic beating, air conditioning and dehumidification systems combined with numerical control of temperature, humidity and pressure effects on flow calibration and filter weighing.
