Particulate matter with an aerodynamic diameter less than 2.5μm (PM) is currently a major air pollutant that has been raising public attention. Studies have found that short/long-term exposure to PM lead detrimental health effects. Since people in most region of the world spend a large proportion of time in dwellings, personal exposure to PM in home microenvironment should be carefully investigated. The objective of this review is to investigate and summary studies in terms of personal exposure to indoor PM pollutants from the literature between 2000 and 2021. Factors from both outdoor and indoor environment that have impact on indoor PM levels were explicated. Exposure studies were verified relating to individual activity pattern and exposure models. It was found that abundant investigations in terms of personal exposure to indoor PM is affected by factors including concentration level, exposure duration and personal diversity. Personal exposure models, including microenvironment model, mathematical model, stochastic model and other simulation models of particle deposition in different regions of human airway are reviewed. Further studies joining indoor measurement and simulation of PM concentration and estimation of deposition in human respiratory tract are necessary for individual health protection.
空气动力学直径小于2.5微米的颗粒物（PM）是目前引起公众关注的主要空气污染物。研究发现，短期/长期接触PM会对健康产生有害影响。由于世界上大多数地区的人在住所中花费大量时间，因此应仔细研究个人在家庭微环境中接触PM的情况。本综述的目的是调查和总结2000年至2021年间文献中关于个人接触室内PM污染物的研究。阐述了来自室外和室内环境中对室内PM水平有影响的因素。对与个体活动模式和接触模型相关的接触研究进行了验证。研究发现，关于个人接触室内PM的大量调查受到浓度水平、接触持续时间和个体差异等因素的影响。综述了个人接触模型，包括微环境模型、数学模型、随机模型以及人体气道不同区域颗粒沉积的其他模拟模型。为了个人健康保护，有必要进一步开展结合室内PM浓度测量与模拟以及人体呼吸道沉积估计的研究。
