The concentrations of particles and nitrogen oxide have been measured in the "blowing cloud" of a smoker. At a distance of 1 m from the smoker, the peak values range from 41 to 750 ppb NO and 3,330 to 99,680 micrograms/m3 particles. These high concentrations decrease very rapidly (half-life period between 2 and 20 s). At a distance of 3 m, there is no more real "blowing cloud". In addition to the sidestream smoke, the relatively high concentrations of particles in the "blowing cloud" of the smoker could also be responsible for the acute irritating effects of the passive smoker.
已对吸烟者“吐出的烟雾”中的颗粒物和氮氧化物浓度进行了测量。在距离吸烟者1米处，一氧化氮（NO）的峰值浓度范围为41至750 ppb，颗粒物浓度范围为3330至99680微克/立方米。这些高浓度会迅速下降（半衰期在2至20秒之间）。在3米的距离处，就不再有真正的“吐出的烟雾”了。除了侧流烟之外，吸烟者“吐出的烟雾”中相对较高的颗粒物浓度也可能是导致被动吸烟者产生急性刺激作用的原因。
