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 less than .0001) 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 less than .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.
采用气相色谱法分析了34名吸烟者和38名非吸烟者家中室内灰尘样本中的尼古丁浓度。对所有家庭的结果进行分析时，发现吸烟量与室内灰尘中尼古丁浓度之间存在强正相关（r = 0.65，p小于0.0001），仅对吸烟者家庭而言，发现存在相当强的正相关（r = 0.35，p小于0.05）。这些数据表明，即使不发生吸烟行为，非吸烟者也可能从可吸入灰尘中吸入烟草成分。对室内灰尘中尼古丁浓度较高的一户家庭中的某人，估计了其1小时内吸入的尼古丁量。计算得出的量为12纳克，与主动吸烟时吸入的量（即600 - 3000纳克/小时）相比非常少。在本研究中，尼古丁是烟草污染的一个指标。假设其他烟草烟雾成分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一个适度的额外来源。
