Investigating Lung Disease in Military Veterans

U.S. Air Force Senior Airman Frances Gavalis, 332nd Expeditionary Logistics Readiness Squadron equipment manager, tosses unserviceable uniform items into a burn pit at Balad Air Base in Iraq. Military uniform items turned in must be burned to ensure they cannot be used by opposing forces. Burn pits are only one potential source of exposure to atmospheric particulates.
