Abstract:
Epidemiological studies have linked particulate matter (PM) exposure to morbidity and mortality from cardiovascular and respiratory disease. In order to monitor and assess the potential PM health risk to deployed military personnel, the U.S. Army must field a portable sampler that can accurately sample particles with an aerodynamic diameter less than or equal to a nominal 2.5 mm (PM2.5). In the study described in this article, the SKC Deployable Particulate Sampler (DPS) was compared to the currently deployed Airmetrics MiniVol portable air sampler in the hot, dry environment of Yuma Proving Grounds, Arizona, and the cold, wet environment of Fort Drum, New York. For all measurements taken and averaged, the DPS and the MiniVol did not differ significantly for mean concentration collected; however, the DPS collected 4.0 times more mass than the MiniVol (p < .05). The DPS was shown to be an improvement over the MiniVol when evaluated for measures of effectiveness, suitability, and performance.
