A new study says that most New York City firefighters and medics whose lungs were damaged after they inhaled the pulverized masonry and glass of the World Trade Center are not improving as time goes by.
Breathing tests conducted on nearly 11,000 firefighters who were at ground zero when the dust was thickest found that 13 percent were still scoring below normal six to seven years later.
That number was down from 18 percent who initially tested below normal after the attacks.
Researchers at the New York City Fire Department and the Albert Einstein College of Medicine are publishing the study tomorrow in the New England Journal of Medicine.
