The aim of this work was to review the existing instrumental methods to monitor airborne nanoparticles in different types of indoor and outdoor environments in order to detect their presence and to characterise their properties. Firstly the terminology and definitions used in this field are discussed, which is followed by a review of the methods to measure particle physical characteristics including number, concentration, size distribution and surface area. An extensive discussion is provided on the direct methods for particle elemental composition measurements, as well as on indirect methods providing information on particle volatility and solubility, and thus in turn on volatile and semivolatile compounds of which the particle is composed. A brief summary of broader considerations related to nanoparticle monitoring in different environments concludes the paper.
这项工作的目的是回顾现有的仪器方法，以监测不同类型室内和室外环境中的空气中纳米颗粒，从而检测它们的存在并表征其特性。首先讨论了该领域中使用的术语和定义，随后回顾了测量颗粒物理特性的方法，包括数量、浓度、尺寸分布和表面积。本文对颗粒元素组成测量的直接方法以及提供颗粒挥发性和溶解性信息的间接方法进行了广泛讨论，进而讨论了颗粒所组成的挥发性和半挥发性化合物。本文最后简要总结了与不同环境中纳米颗粒监测相关的更广泛考虑因素。
