Veterans who served in Iraq, Afghanistan, or any other areas in Southwest Asia should register if they have concerns about toxic exposure while serving in Southwest Asia.
Long-term medical issues have been known to arise as a result of airborne hazards such as smoke and fumes from burn pits, fuel, aircraft exhaust, sand, dust, general air pollution, oil well fires, and blast or noise injuries. The VA encourages Veterans to register as well as talk to their healthcare provider and file a claim for benefits.
