Abstract or Description

Goals and Objectives: The purpose of this study was to assess particulate matter (PM2.5 and PM10) in the air of homes in south-eastern Georgia.

Theoretical Framework: Given that many Americans spend the majority of their time indoors, the quality of air in one's home is crucial to their health and quality of life. Studies have reported an increased risk in hypertension from long-term exposure to particulate matter. In addition, increased visits to the pediatric emergency department for upper respiratory infections as well as asthma or wheeze have also been associated with PM2.5 concentrations. The prevalence of hypertension, upper respiratory infections, and asthma is on the rise, thus air quality may be an area of concern.

Methodology/Data: Airborne particles, including particles in the size range of PM10 and PM2.5 (respirable particles that can reach to lower respiratory tract and alveoli) were monitored using a 6-channel (0.3, 0.5, 1.0, 2.5, 5.0 and 10 µm) particle counter with graphical interface which can store up to 5000 sample records on micro SD card. A total of 6 homes were sampled (n=6), collecting a total of 10 data points for each particle size per home. The particle counter ran 10 times, each for one minute. The residential indoor mean particle concentration number (particles/m3) was (M = 2.6 X 105, SD = 4.4 X 105) and (M = 1.9 X 104, SD = 1.6 X 104) for PM2.5 and PM10, respectively. Other parameters such as temperature, humidity, and time of day were also recorded.

Educational/Field Significance: The preliminary data shows average particle number concentrations in the homes of south eastern Georgia.

Proposed Significance/Outcome: These can be compared to the respiratory symptoms of home owners to determine whether or not there is a correlation between particle number concentrations and the development or exacerbation of respiratory symptoms.
