Nicotine concentrations were measured in saliva and urine samples collected from 82 smokers and 56 non-smokers after a morning at work. Each subject answered a series of questions related to their recent intentional or passive exposure to tobacco smoke. All non-smokers had measurable amounts of nicotine in both saliva and urine. Those non-smokers who reported recent exposure to tobacco smoke had significantly higher nicotine concentrations (p less than 0.001) than those who had not been exposed; their concentrations overlapped those of smokers who had smoked up to three cigarettes before sampling had the greatest influence on nicotine concentrations (r=0.62 for saliva and r=0.51 for urine). Neither the nicotine for yield of cigarettes nor the self-reported degree of inhalation had any significant effect on nicotine concentrations.
在工作一个上午后，从82名吸烟者和56名不吸烟者中收集唾液和尿液样本，测量其中的尼古丁浓度。每位受试者回答了一系列与他们近期主动或被动接触烟草烟雾相关的问题。所有不吸烟者的唾液和尿液中都含有可测量的尼古丁量。那些报告近期接触过烟草烟雾的不吸烟者，其尼古丁浓度显著高于未接触者（p小于0.001）；他们的浓度与采样前吸了多达三支烟的吸烟者的浓度重叠。工作时长对尼古丁浓度影响最大（唾液中r = 0.62，尿液中r = 0.51）。香烟的尼古丁含量和自我报告的吸入程度对尼古丁浓度均无显著影响。
