Certain 9/11 lung injuries may be reversible: study

October 10, 2012

New York – A group of workers exposed to toxic dust at the World Trade Center site have recovered some lung function, leading researchers to suggest airway injury may be reversible, according to a study from the NYU Langone Medical Center.

Spirometry test results for almost 950 people in the WTC Environmental Health Center treatment program showed gradual improvement, but the level varied based on initial spirometry pattern and exposure, the study abstract stated. Heavy smokers in particular did not show improved function.

The study was published in the October issue of the Journal of Occupational and Environmental Medicine.
