Contamination by environmental tobacco smoke (ETS) on premises where smoking is permitted is evaluated. Although all target VOCs evaluated show significant differences between smoking and nonsmoking indoors, the results obtained indicate that 2,5-dimethylfuran is the most appropriate and effective marker of ETS contamination given that this compound is only detected in environments where people have smoked and so the detection of this compound cannot be attributed to other contamination sources such as traffic. Moreover, the air levels of this compound due to coffee aroma are below the detection limits for this methodology. A preliminary study is performed to evaluate whether 2,5-dimethylfuran, a smoking breath biomarker, can be detected in passive smokers working in smoking environments. The compound was continuously detected in the breath of nonsmoking employees after being in direct contact with ETS for just a few hours. The Tedlar gas sampling bags had 5% loss of 2,5-dimethylfuran after 3 h of storage, which we took as the maximum recommended period for air sample storage.
对允许吸烟场所的环境烟草烟雾（ETS）污染进行评估。虽然评估的所有目标 VOCs 在吸烟和非吸烟室内均显示出显著差异，但结果表明，2,5-二甲基呋喃是评估 ETS 污染最适宜和有效的标志物，因为只有在有人吸烟的环境中才能检测到这种化合物，因此不能将其检测归因于其他污染源，如交通。此外，由于咖啡香气，该化合物在空气中的水平低于该方法的检测限。进行了一项初步研究，以评估作为吸烟呼吸生物标志物的 2,5-二甲基呋喃是否可以在处于吸烟环境中的被动吸烟者的呼吸中被检测到。在与 ETS 直接接触仅几个小时后，非吸烟员工的呼吸中连续检测到该化合物。Tedlar 气体采样袋在储存 3 小时后有 5%的 2,5-二甲基呋喃损失，我们将其视为空气样本储存的最大推荐时间。
