作者用尼古丁个体剂量器佩带在一个不吸烟者身上,在各种生活环境中逗留,测定尼古丁的浓度,并以一个人的呼吸量为0.48m~3/小时来估算每小时吸入尼古丁的量,再以主动吸入一支普通香烟为0.9mg尼古丁来换算被动吸烟者相当于主动吸入香烟的支数(见表)。测定结果表明尼古丁在各种生活环境中的浓度范隔在1.8(实验室)至83μg/m~3(小汽车),因此在这些生活环境中被动吸烟者吸入的尼古丁可估计为0.9～ The authors used a nicotine individual dosimeter to wear on a non-smoker, stayed in various living environments, measured the nicotine concentration, and estimated the amount of nicotine inhaled per hour with a person’s breathing of 0.48 m 3 / hour, Active inhalation of an ordinary cigarette 0.9mg nicotine to convert passive smoker is equivalent to the number of active inhaled cigarettes (see table). The results showed that nicotine concentrations ranged from 1.8 (laboratory) to 83 μg / m 3 (car) in a variety of living environments, so nicotine inhaled by passive smokers in these living environments was estimated at 0.9 -
