采用气相色谱法对34名吸烟者和38名非吸烟者家中的灰尘样品中尼古丁浓度进行了分析。 当对所有家庭的结果进行分析时，发现吸烟量与室内灰尘中的尼古丁浓度之间存在很强的正相关性（r = 0.65，p <0.001），并且仅在吸烟者的家中发现了相当强的正相关性（r = 0.35，p <0.05）。 这些数据表明，不吸烟者可能会吸入烟草成分的可吸入粉尘，即使没有发生吸烟。 在1小时内吸入的尼古丁量是估计的人在其中一个家庭，有一个高尼古丁浓度的房屋灰尘。 计算出的量12 ng与主动吸烟时吸入的量相比非常小（即，600-3 000纳克/小时）。 在这项研究中，尼古丁是烟草污染的标志。 假设其他烟草烟雾剂对室内灰尘的亲和力与尼古丁相似或更小，我们得出结论，吸入室内灰尘仅构成非自愿吸烟的适度额外来源。
The nicotine concentration in samples of house dust from the homes of 34 smokers and 38 nonsmokers was analyzed using a gas chromatographic method. A strong positive correlation (r = .65, p < .001) between the amount smoked and the nicotine concentration in the house dust was found when the results from all homes were analyzed, and a fairly strong positive correlation (r = .35, p < .05) was found for smokers' homes only. These data suggest that the nonsmoker may inhale tobacco constituents from respirable dust, even if smoking does not occur. The amount of nicotine inhaled during 1 h was estimated for someone in one of the homes where there was a high nicotine concentration in the house dust. The calculated amount, 12 ng, is very small compared with the amount inhaled when active smoking occurs (i.e., 600-3 000 ng/h). In this study, nicotine was a marker of tobacco pollution. Assuming that other tobacco smoke agents have a similar or smaller affinity to house dust as that of nicotine, we conclude that house dust inhalation constitutes only a modest additional source of involuntary smoking.
