在环境室和现场研究中，将烟草燃烧产生的气相尼古丁和可吸入悬浮颗粒物（RSP）排放作为环境烟草烟雾（ETS）的标志物进行了评价。 测试结果显示，不同品牌香烟的尼古丁和可吸入悬浮粒子的排放量相似，而且这两种污染物的排放量在封闭环境中很容易测量。 该实地研究收集了96个住宅的1周气相尼古丁和可吸入悬浮粒子的测量结果以及广泛的来源使用信息。 气相尼古丁测量与吸烟的数量密切相关，并且高度预测烟草燃烧产生的可吸入悬浮颗粒物质量。 所观察到的气相尼古丁和RSP之间的现场关联与室研究一致。 这里报道的室内和现场研究表明，气相尼古丁是住宅室内环境中环境烟草烟雾的合适的定性和定量标志物。 由于可吸入悬浮粒子的本底水平来自其他来源，因此在测定可吸入悬浮粒子中可归因于ETS的部分之前，室内测量的可吸入悬浮粒子应辅以测量烟草消耗量或测量气相尼古丁浓度。
Vapor-phase nicotine and respirable suspended particle mass (RSP) emissions from tobacco combustion were evaluated as markers for environmental tobacco smoke (ETS) in an environmental chamber and a field study. The chamber results indicated that emissions of vapor-phase nicotine and RSP were similar among brands of cigarettes and both contaminants were emitted in quantities that are easily measured in enclosed environments. The field study collected 1-week measurements of vapor-phase nicotine and RSP as well as extensive source use information in 96 residences. Vapor-phase nicotine measurements were closely related to the number of cigarettes smoked and were highly predictive of respirable suspended particle mass generated by tobacco combustion. The observed field association between vapor-phase nicotine and RSP was consistent with chamber studies. The chamber and field studies reported here indicate that vapor-phase nicotine is a suitable qualitative and quantitative marker for environmental tobacco smoke in the residential indoor environment. Due to background levels of RSP from other sources, RSP measurements indoors should be supplemented by a measure of the quantity of tobacco consumed or a measure of the vapor-phase nicotine concentration before the portion attributable to ETS can be determined.
