Forty subjects were exposed to cigarette smoke produced by a smoking machine in a climatic chamber. The degree of air pollution due to cigarette smoke corresponded to 2.5 and 1.3 ppm delta CO. The concentrations of particulate matter, NO and NO2, were measured. The effects on subjective irritation, annoyance and eye blinking rate were determined. All measured effects increased with increasing smoke concentration as well as with exposure duration. Based on these effects, a tolerable limit in the range between 1.5 and 2.0 ppm delta CO is proposed.
四十名受试者在气候舱内暴露于吸烟机产生的香烟烟雾中。香烟烟雾造成的空气污染程度相当于2.5 ppm和1.3 ppm的一氧化碳增量。测量了颗粒物、一氧化氮和二氧化氮的浓度。测定了对主观刺激、烦恼和眨眼率的影响。所有测量到的影响都随着烟雾浓度的增加以及暴露时间的延长而增加。基于这些影响，提出了1.5至2.0 ppm一氧化碳增量之间的可耐受限度。
