A range of health problems are linked to the pits on military bases in Iraq and Afghanistan. Toxic substances have been found in the smoke.
The noxious smoke plumes that wafted over the military base in Balad, Iraq, alarmed Lt. Col. Michelle Franco. The stench from a huge burn pit clung to her clothing, skin and hair.
She wheezed and coughed constantly. When Franco returned to the U.S., she was diagnosed with reactive airway dysfunction syndrome. She is no longer able to serve as an Air Force nurse.
