摘要
本文作者为探明被动吸烟者的实际暴露水平,在实验小室内以IP和CO为指标,对多种吸烟状况进行了连续、自动监测。结果表明,室内香烟烟雾有一个随时间变化而增长和衰减的过程,影响香烟烟雾的主要因素为吸烟量、室内容积和室内通风换气率。
In order to find out the real exposure level of passive smokers, the authors conducted a series of measurements of representative pollutants, IP and CO, by automatic monitoring instruments in the experimental room, where volunteers smoked a certain amount and different kinds of cigarettes in unit time according to the experiment designed. The results show. (1) Indoor cigarette smoke has a dynamic variation pattern. (2) IP and CO mean concentration within 60 minutes will reach 1.0mg/m^3 and 3.5mg/m^3 respectively, when one cigarette is smoked at speed 7.5min/cig in 10m^3 room which air exchange rate is 1.5h^(-1); (3) the main factors which influence the variation of indoor cigarette smoke are the number of cigarette smoked, room size and indoor air exchange rate.
