To detect the difference of the amount of particles within the smoke
of filtered cigarette and the second hand smoke released into a room from a
cigarette. In doing this, it will be determined what harm these types of
smoke can cause to the smoker and to those in the same room.
For this experiment, filtered and non-filtered cigarettes were used.
An apparatus to collect the smoke of the two types of cigarettes was
constructed. Two 250ml flasks were taken and had a piece of filter placed
over the mouth of each flask, secured with a 1-hole rubber stopper. Tubing
connected both flasks to the cigarettes used. Before the smoke was
collected, the filter paper was weighed and the results were recorded. Once
the filtered and non-filtered cigarette burned down to its last centimeter,
after a period of 3-5 minutes, it was put out and the filter paper was
weighed once again and the results were recorded.
It was found that there was a difference in weights of solids between
the filtered smoke and the non-filtered smoke. When collecting the smoke
from the non-filtered cigarette, .008 grams was recorded for the smoker's
flask and .007 grams was recorded for the room's flask. Once the weights
were compared to one another, the solids accounted for 87.5%. While the
smoke from a filtered cigarette collected .006 grams in the smoker's flask
and .008 grams in the room's flask. When these weights were compared to one
another, the solids accounted for 133.3%.
It was determined that while being in a room with a smoker, a non-
filtered cigarette gave off fewer particles than a filtered cigarette.
Filtered smoke proved to be more harmful than non-filtered smoke, but both
types of smoke still cause damage nonetheless.
In conclusion, it was found that a filt
