Abstract：
Recent studies proves that indoor air chemistry differs in many aspects from atmospheric one. People send up to 90 % of their life indoors being exposed to pollutants present in gas, particle and solid phase. Particle phase indoor is composed of particles emitted from various sources, among which there is an indoor source - secondary chemical reactions leading to formation of secondary organic aerosol (SOA). Lately, researchers\' attentions turned towards the ultrafine particles, for there are still a lot of gaps in knowledge concerning this field of study, while there is evidence of negative influence of ultrafine particles on human health. Presented review sums up current knowledge about secondary particle formation in indoor environment and development of analytical techniques applied to study those processes. The biggest concern today is studying ROS, for their lifetime in indoor air is very short due to reactions at the very beginning of terpene oxidation process. Another interesting aspect that is recently discovered is monoterpene autooxidation process that leads to HOMs formation that in turn can influence SOA formation yield. A complex studies covering gas phase and particle phase characterization, but also toxicological studies are crucial to fully understand indoor air chemistry leading to ultrafine particle formation.
摘要：
最近的研究证明，室内空气化学在许多方面与大气化学不同。人们将其90%的生活都留在室内，暴露于气体中的污染物，颗粒和固相。粒子相室内由各种来源发射的粒子组成，其中有一个室内来源-二次化学反应，导致形成二次有机气溶胶（SOA）。最近,研究人员的注意力转向了超细颗粒，因为关于这个研究领域的知识还有很多空白，虽然有证据表明超细颗粒对人体健康有负面影响。提出的评论总结了有关室内环境中二次粒子形成的最新知识以及用于研究这些过程的分析技术的发展。今天最关心的是研究ROS，因为它们在室内空气中的寿命非常短，因为在萜烯氧化过程的开始反应。最近发现的另一个令人感兴趣的方面是导致HOM形成的单萜自氧化过程,其进而可以影响SOA形成产率。涵盖气相和颗粒相表征的复杂研究，而且毒理学研究对于充分了解室内空气化学导致超细颗粒形成至关重要。
