对工作区和生活区环境的日益关注强调了从供应给这些区域的空气中充分去除颗粒物、获得关于这些颗粒物性质的详细信息以及开发针对这些应用的颗粒物测量方法的必要性。有关室内和进气处理和清洁设备携带的颗粒物的化学和物理性质的信息对于空气清洁系统的设计至关重要，并且对于在此类系统的实验室评估中使用的具有适当代表性的测试粉尘的制备是必要的。空气净化设备的实验室和现场评估都要求有足够的采样和分析技术。 因此，有必要开发和评估有效的方法，以便方便地评估室内和进气中空气颗粒物的重要特征。本研究的目的是对适用于对单户住宅和一般办公楼的空气处理系统的室内空气和进气颗粒物含量进行客观描述（包括数量和物理特征）的技术进行分析和评估。此外，作为技术适用性的证明，在一年四季中的每个季节，从代表性的空气处理系统中收集颗粒物样本，并分析特定的颗粒物特征。 引文:研讨会论文，佐治亚州亚特兰大，1978年

Increasing concern for the environment in working and living areas has accentuated the need for adequate removal of particulate matter from the air supplied to these areas, for detailed information on the nature of these particulates, and for development of methods for particulate measurements specific to these applications. Information concerning the chemical and physical nature of particulate matter carried by indoor and intake air handling and cleaning equipment is critical to the design of air cleaning systems and is necessary for the formulation of suitably representative test dusts used in laboratory evaluations of such systems. Both laboratory and field evaluations of air cleaning equipment require that adequate sampling and analysis techniques be available. It is necessary, then, that efficient methods be developed and evaluated which allow convenient assessment of the important characteristics of airborne particulate matter found in indoor and intake air.The objective of this study was to provide analyses and evaluations of techniques suitable for providing an objective description (including amounts and physical characteristics) of the particulate content of indoor air and intake air for air-handling systems in both single-family dwellings and general office buildings. Further, as a demonstration of technique suitability, samples of particulates from representative air-handling systems were collected during each of the four seasons of the year and analyzed for specific particle characteristics.
