To evaluate the actual level of exposure of nonsmokers to tobacco smoke in their living environments, a convenient personal monitor of nicotine specific for tobacco smoke has been developed. The nicotine personal monitor consists of a sampler tube containing 450 mg of Uniport-S coated with silicon OV-17 and a portable sampling pump with a mechanical counter for obtaining total sampling volume. Using the personal monitor attached to a nonsmoker, ambient nicotine was collected in the sampler tube by drawing environmental air at a constant flow rate for a maximum period of 8 hr. The collected nicotine was desorbed by heating and directly transferred onto a GC column with a carrier gas. The amounts of nicotine inhaled by passive smoking in various living environments were estimated to be in the range of 0.9-40 micrograms/hr. These levels are equivalent to those from the active smoking of about 0.001-0.044 ordinary cigarettes in 1 hr.
为评估非吸烟者在其生活环境中接触烟草烟雾的实际水平，已研发出一种便捷的、专门用于检测烟草烟雾中尼古丁的个人监测器。该尼古丁个人监测器由一个装有450毫克涂有硅OV - 17的Uniport - S的采样管和一个带有机械计数器以获取总采样体积的便携式采样泵组成。将个人监测器佩戴在非吸烟者身上，通过以恒定流速抽取环境空气，在最长8小时的时间内，在采样管中收集环境尼古丁。收集到的尼古丁通过加热解吸，并随载气直接转移到气相色谱柱上。据估计，在各种生活环境中，被动吸烟吸入的尼古丁量在0.9 - 40微克/小时范围内。这些水平相当于1小时内主动吸食约0.001 - 0.044支普通香烟所摄入的尼古丁量。
