Objective: To detect the amount of particular matter collected from the
smoker's end of a cigarette and the amount of second hand smoke released
Materials and Methods/Procedures: Two each of a 250 ml filter flask, a
piece of filter paper, a 1-hole rubber stopper, glass tubing, a glass
funnel and rubber tubing were assembled as required, and the filter flask
was attached to a water aspirator. The filter papers were removed, weighed
to the nearest 0.001 g, and replaced on the apparatus. A non-filtered
cigarette was inserted into the funnel, which was then clamped pointing up.
A second funnel was clamped approximately a half inch above the cigarette
funnel in order to collect the second hand smoke in the room, and enough
space was allowed between the funnels to allow air and catch all of the
smoke. The water aspirators were turned on, the cigarette was lit, and the
aspirators were adjusted so that the cigarette burned over a period of 3-5
minutes. After the cigarette burned down to the last centimeter, the
aspirators were turned off, the cigarette was removed and the filter papers
were removed and weighed. The initial weight of the filter paper was
subtracted from the final weight. The solids collected from the second
hand smoke funnel were divided by the solids collected for the smoker's
funnel, and multiplied by 100 to obtain the percent of solids in room
smoke. The procedure was repeated with a filtered cigarette and the
Results: In the non-filtered cigarette experiment, the initial filter
paper weight of the smoker's flask was .223g, while the paper of the room
flask weighed .234g. After collecting solids, the weight of the smoker's
flask paper was .231g and the room flask paper weighed .241g. The weight
of the solids collected were: smoker's flask-.008g, and room flask-.007g.
The percentage between room solid smoke and smoker's smoke wa
