气态有机化合物,主要是挥发性有机化合物(VOCs),在我们每天花费大部分时间的各种室内环境中,已经成为人们广泛关注的问题。的来源,Compositions,变体,室内挥发性有机化合物的汇极其复杂,人们对它们对人类健康的潜在影响了解较少。由于在过去的二十年中部署了最先进的实时质谱,我们对来源的理解,室内挥发性有机化合物的动态变化和化学转化得到了显著改善。这篇综述旨在总结质谱测量在最近的室内研究中的主要发现,包括住宅,教室,office,体育中心,等。源头和汇,室内挥发性有机化合物的组成和分布,和因素(例如,人类活动,空气交换率,温度和湿度)驱动室内VOC的变化进行了讨论。VOCs的气体-颗粒分配和二次氧化过程的物理和化学过程,并总结了它们对人类健康的影响。最后,对室内VOCs测量和室内化学的未来研究方向提出了建议。
Gaseous organic compounds, mainly volatile organic compounds (VOCs), have become a wide concern in various indoor environments where we spend the majority of our daily time. The sources, compositions, variations, and sinks of indoor VOCs are extremely complex, and their potential impacts on human health are less understood. Owing to the deployment of the state-of-the-art real-time mass spectrometry during the last two decades, our understanding of the sources, dynamic changes and chemical transformations of VOCs indoors has been significantly improved. This review aims to summarize the key findings from mass spectrometry measurements in recent indoor studies including residence, classroom, office, sports center, etc. The sources and sinks, compositions and distributions of indoor VOCs, and the factors (e.g., human activities, air exchange rate, temperature and humidity) driving the changes in indoor VOCs are discussed. The physical and chemical processes of gas-particle partitioning and secondary oxidation processes of VOCs, and their impacts on human health are summarized. Finally, the recommendations for future research directions on indoor VOCs measurements and indoor chemistry are proposed.
