Key Details
Official Description
Warfighters can be deployed in operational environments with high airborne particulate matter (PM) levels; these events lead to a significant risk of developing cardiovascular and pulmonary disease. Adverse health effects, including cardiovascular and pulmonary disease, are well-documented consequences of exposure to high levels of PM with aerodynamic diameters of less than 10 μm (PM10) and especially less than 2.5 μm (PM2.5). In many deployment environments as well as in training facilities (e....
