The impact of indoor air quality on human health is gaining importance as people spend 90% of their time indoors. It has been established that human occupancy is a significant contributor to indoor Volatile Organic Compound (VOC) concentrations and is of significant concern regarding occupant health, and yet human VOC emissions remain largely uncharacterised. In the current study, we review recent research that examines the contributions of humans to the indoor VOC profile in occupied spaces, with a focus on study characteristics. This investigation identified a hierarchy of factors contributing to inter-study variations in human biogenic VOC (HVOC) levels measured indoors. We found that the factors contributing to the variation in reported HVOC emissions are related to the sampling techniques used, the test conditions, occupant related factors sample analysis. Contrasting findings on issues such as the effect of nutrition and smoking are discussed. Conclusions were reached about the recent advancements and nature of results and the need to use larger datasets, and recommendations regarding global guidelines and future testing have been made. We advocate for a unified approach in future studies, promoting more coordinated data collection and reporting and fostering the development of impactful applications.

人类室内排放的挥发性有机化合物——测量、测试条件和分析技术综述

由于人们 90% 的时间都在室内度过，室内空气质量对人类健康的影响变得越来越重要。已经确定，人类居住是室内挥发性有机化合物 (VOC) 浓度的重要影响因素，并且对居住者的健康至关重要，但人类 VOC 排放在很大程度上仍然未知。在当前的研究中，我们回顾了最近的研究，这些研究考察了人类对占用空间中室内 VOC 分布的贡献，重点关注研究特征。这项调查确定了导致室内测量的人类生物挥发性有机化合物 (HVOC) 水平的研究间差异的一系列因素。我们发现，导致报告的 HVOC 排放量变化的因素与所使用的采样技术、测试条件、与居住者相关的因素样本分析有关。讨论了有关营养和吸烟的影响等问题的对比研究结果。就最近的进展和结果的性质以及使用更大数据集的必要性得出了结论，并就全球指南和未来测试提出了建议。我们主张在未来的研究中采用统一的方法，促进更加协调的数据收集和报告，并促进有影响力的应用程序的开发。
