PUBLIC HEALTH ADVISORY CONCERNING AIR QUALITY IN THE AFFECTED
AREA OF THE WORLD TRADE CENTER DISASTER
The NYC Department of Health (DOH), in collaboration with the City, State, and Federal
agencies, is closely monitoring and analyzing air quality data in the wake of the World Trade
Center disaster. Following the collapse of the Twin Towers, significant quantities of smoke and
dust have been released into die air. The plume of smoke contained dust, ash, soot, and other
burning materials present at the site.
In general, dusts can cause respiratory symptoms and eye and throat irritation. Because dust will
continue to remain in the air during the ensuing clean-up efforts following the World Trade
Center disaster, residents in the vicinity of the World Trade Center are encouraged to take
precautions when they return to their homes.
