Abstract

Particulate matter (PM) is an important player in indoor air quality. Even though PM limit values are in force for more than a decade in Europe and reference methods are well in place for ambient air, measuring indoor PM concentration still remains a challenge and standardizing a measurement protocol is complex. As people stay most of their time indoors, indoor PM is of great interest in terms of public health, as concentration can be drastically different to the one outdoors. This review aims to provide key information to the indoor air monitoring communities, to better understand principal methods suitable for the analysis of indoor PM with their respective main influencing parameters. Advantages and drawbacks of each method are discussed and specific awareness is raised to avoid wrong data interpretation in specific situations. The inter-instrument deviation is also explained and, when possible, methods to correct are proposed.

摘要

颗粒物 (PM) 是影响室内空气质量的重要因素。尽管 PM 限值在欧洲实施了十多年，并且环境空气的参考方法也很到位，但测量室内 PM 浓度仍然是一个挑战，并且标准化测量协议是复杂的。由于人们大部分时间都待在室内，因此室内 PM 对公众健康非常重要，因为浓度可能与室外完全不同。本综述旨在为室内空气监测社区提供关键信息，以更好地了解适用于室内 PM 分析的主要方法及其各自的主要影响参数。讨论了每种方法的优点和缺点，并提出了具体的认识，以避免在特定情况下错误的数据解释。
