被动吸烟是最常见的一种室内空气污染。为进一步阐明被动吸烟的影响,作者测定了实验性被动吸烟时吸入气与呼出气的尼古丁浓度,计算了尼古丁的吸收率。受试者为18～22岁的17名非吸烟健康女性。实验在长8m、宽6m、高2.5m的房间进行,室内自动通风换气(6.2次/小时)。室中央每10分钟燃5支香烟(60分钟共30支)。在整个受试期间受试者保持坐姿和距香烟1m。采样时间为受试前10分钟及受试10分钟、30分钟和50分钟。受试者佩带特制面具,面具 Passive smoking is the most common type of indoor air pollution. To further elucidate the effects of passive smoking, the authors measured the nicotine concentrations of inhaled and exhaled gases during experimental passive smoking and calculated the nicotine absorption rate. The subjects were 17 non-smoking healthy women aged 18-22 years. The experiment was carried out in a room of 8m in length, 6m in width and 2.5m in height with automatic ventilation in the room (6.2 times / hour). The center of the room burns 5 cigarettes every 10 minutes (30 for 60 minutes total). Subjects remained seated and 1 m from cigarettes throughout the trial. Sampling time is 10 minutes before the test and the test 10 minutes, 30 minutes and 50 minutes. Subjects wear special masks, masks
