背景资料：沉积在表面的尼古丁已被证明与空气中的化学物质发生反应，导致致癌物质的形成，并导致三手接触。虽然先前的研究表明，在烟草吸烟者的家中尼古丁残留，没有检查电子烟（电子烟）用户的homes.Methods的尼古丁残留：我们测量了尼古丁的表面上的家庭的8电子烟用户，6吸烟者，和8个非用户的尼古丁含尼古丁的产品在美国西部纽约。从地板、墙壁和窗户上取三个表面擦拭样品。尼古丁是从湿巾中提取出来的，并使用气相色谱法进行分析。结果：一半的电子烟使用者的家中表面上有可检测到的尼古丁水平，而所有烟草吸烟者的家中都发现了尼古丁。在一半不使用含尼古丁产品的家庭中也检测到微量尼古丁。电子烟使用者家中的尼古丁水平显著低于吸烟者家中的尼古丁水平（平均浓度为7.7 +/- 17.2 vs. 1303 +/- 2676 μ g/m2; p < 0.05）。电子烟使用者和非使用者家中的尼古丁含量无显著差异（p > 0.05）。结论：尼古丁是室内表面常见的污染物。与吸烟相比，在室内使用电子烟会显著减少三手接触尼古丁。(C)2015 Elsevier B.

Background: Nicotine deposited on the surfaces has been shown to react with airborne chemicals leading to formation of carcinogens and contributing to thirdhand exposure. While prior studies revealed nicotine residues in tobacco smokers' homes, none have examined the nicotine residue in electronic cigarette (e-cigarette) users' homes.Methods: We measured nicotine on the surfaces in households of 8 e-cigarette users, 6 cigarette smokers, and 8 non-users of nicotine-containing products in Western New York, USA. Three surface wipe samples were taken from the floor, wall and window. Nicotine was extracted from the wipes and analyzed using gas chromatography.Results: Half of the e-cigarette users' homes had detectable levels of nicotine on surfaces whereas nicotine was found in all of the tobacco cigarette smokers' homes. Trace amounts of nicotine were also detected in half of the homes of non-users of nicotine-containing products. Nicotine levels in e-cigarette users homes was significantly lower than that found in cigarette smokers homes (average concentration 7.7 +/- 17.2 vs. 1303 +/- 2676 mu g/m(2); p < 0.05). There was no significant difference in the amount of nicotine in homes of e-cigarette users and non-users (p > 0.05).Conclusions: Nicotine is a common contaminant found on indoor surfaces. Using e-cigarettes indoors leads to significantly less thirdhand exposure to nicotine compared to smoking tobacco cigarettes. (C) 2015 Elsevier B.V. All rights reserved.
