The Quantitation of Smoke Uptake, two second puff of 35 ml every 60 seconds. Not only will smoke delivery vary in magnitude but also in quality since smoke composition may differ according to the manner in which the cigarette is smoked. For example, the tar:nicotine ratio and the carbon monoxide:nicotine ratio have been shown to depend on puff volume (1).interference 发表于 2025-3-23 17:07:18

Physiological Effects of Changing Cigarette Nicotine Yield,t factor concerns the quantities of the smoke constituents which reach the tissues. This is largely influenced by differences in the way that people smoke, and this paper is concerned with the problems of measuring the process and the effects of smoking two cigarettes which differ principally in their nicotine yields.ADAGE 发表于 2025-3-23 22:30:49

The Quantitation of Smoke Uptake,rbon monoxide, tar and the thousands of other chemicals in cigarette smoke will vary considerably from one person to another. For the majority of individuals delivery will be quite different, either greater or smaller, than the yields produced by analytical smoking machines which are set to give one
