电子烟消费（vaping）作为传统烟草吸烟的替代品销售。从技术上讲，含有载液、香料和任选尼古丁的化学品混合物被蒸发和吸入。本研究的目的是确定在接近真实使用条件下，在8 m3的排放测试室中，电子烟中挥发性有机化合物（VOC）和（超）细颗粒（FP/UFP）的释放。此外，吸入的混合物在小室中进行分析。使用电子烟后，可以确定FP/UFP和VOC的增加。气相中的主要成分是1，2-丙二醇、1，2，3-丙三醇、二醋精、调味剂和痕量尼古丁。因此，必须从电子烟的消费中预期被动vaping。此外，吸入的气溶胶在人肺中经历了被认为归因于沉积和蒸发的变化。电子烟的消费标志着室内环境中化学品和气溶胶暴露的新来源。为了评估电子烟对室内空气质量的影响，并估计被动吸烟的可能影响，需要有关释放蒸汽的化学特性的信息。
Electronic cigarette consumption (vaping) is marketed as an alternative to conventional tobacco smoking. Technically, a mixture of chemicals containing carrier liquids, flavors, and optionally nicotine is vaporized and inhaled. The present study aims at the determination of the release of volatile organic compounds (VOC) and (ultra)fine particles (FP/UFP) from an e-cigarette under near-to-real-use conditions in an 8-m3 emission test chamber. Furthermore, the inhaled mixture is analyzed in small chambers. An increase in FP/UFP and VOC could be determined after the use of the e-cigarette. Prominent components in the gas-phase are 1,2-propanediol, 1,2,3-propanetriol, diacetin, flavorings, and traces of nicotine. As a consequence, passive vaping must be expected from the consumption of e-cigarettes. Furthermore, the inhaled aerosol undergoes changes in the human lung that is assumed to be attributed to deposition and evaporation. Practical Implications The consumption of e-cigarettes marks a new source for chemical and aerosol exposure in the indoor environment. To evaluate the impact of e-cigarettes on indoor air quality and to estimate the possible effect of passive vaping, information about the chemical characteristics of the released vapor is needed.
