Objective: To detect the amount of particular matter collected from thesmoker's end of a cigarette and the amount of second hand smoke releasedMaterials and Methods/Procedures: Two each of a 250 ml filter flask, apiece of filter paper, a 1-hole rubber stopper, glass tubing, a glassfunnel and rubber tubing were assembled as required, and the filter flaskwas attached to a water aspirator. The filter papers were removed, weighedto the nearest 0.001 g, and replaced on the apparatus. A non-filteredcigarette was inserted into the funnel, which was then clamped pointing up. A second funnel was clamped approximately a half inch above the cigarette
The water aspirators were turned on, the cigarette was lit, and theaspirators were adjusted so that the cigarette burned over a period of 3-5minutes. The procedure was repeated with a filtered cigarette and theresults were compared. Results: In the non-filtered cigarette experiment, the initial filterpaper weight of the smoker's flask was . 223g, while the paper of the roomflask weighed . After collecting solids, the weight of the smoker'sflask paper was . The weightof the solids collected were: smoker's flask-. Discussion: The data from the non-filtered cigarette procedure shows that87. The solids collected from the secondhand smoke funnel were divided by the solids collected for the smoker'sfunnel, and multiplied by 100 to obtain the percent of solids in roomsmoke. Conclusion: Cigarette smoke contains a number of solid particles which canbe inhaled by both the smoker and those nearby in terms of second-handsmoke.
