The Determination of the Concentration of Particulate Matter in Different Rooms of a Household.

Inhaling indoor air pollution can gradually lead to lung disease, respiratory tract infections, lung cancer, and asthma. Biological pollutants including molds, bacteria dust mites, and animal dander are sources of particulate matter that promote poor indoor air quality. The purpose of this research was to determine the concentration of particulate matter in a household and also to determine which particle collection would be densest. It was hypothesized that the densest concentration of particles would be the carpet fibers collected. Twenty-five index cards designed to collect dust, carpet fibers, animal hair, skin cells, dog hair, and any unknown particles were equally distributed throughout five different rooms in a household. The rooms tested were the kitchen, bedroom, laundry room (where the family dog is kept), FROG (den) and the bathroom. A 5x6 contingency table was made comparing the location of the cards in the household and the different particles that were found. Using the chi-square statistical test, the FROG (den) collected the greatest amount of particulate matter, while dust was the most abundant particle. The experimental hypothesis was not supported.
