Toxic dust from 2001 World Trade Center collapse causes ongoing health crisis 25 years later

Search and rescue in the wreckage

Following the collapse of the World Trade Center towers on 11 September 2001, tens of thousands of rescue and recovery personnel deployed to lower Manhattan. Curt Andrews, a 41-year-old volunteer firefighter from Connecticut, packed supplies for two weeks and drove 1.5 hours with fellow firefighters to assist at Ground Zero. The twin towers had collapsed before the team arrived, leaving surrounding streets blanketed in knee-deep ash that Andrews described as walking through snow. The emergency crews searched for survivors under collapsed structures while listening to distress alarms from equipment belonging to more than 300 firefighters who died in the collapse. Rescuers operated without protective face masks, spending their initial nights resting on curbs and going without showers for the entire week while coated in particulate matter.

We were there to help others. We did not think about ourselves.

Hazardous exposure at Ground Zero

Emergency crews endured acute respiratory irritation, persistent coughing, and continuous exposure to airborne toxins while working across the disaster site. Late on his first night, Andrews and fellow rescuers located an injured survivor trapped under heavy wreckage shortly before midnight.

At 11:00, shortly before midnight, we found someone, a man who was still alive. A steel beam had driven into his arm. We had doctors come to him who administered morphine. Then we had to amputate his arm and rescue him from the pile of rubble. He survived.

The rescued man was the only survivor Andrews located during his seven days in the disaster area. Throughout the recovery operations, personnel inhaled and absorbed a toxic mixture containing pulverized concrete, glass, drywall, and burned plastics across their respiratory systems and skin. Subterranean fires in the debris piles continued burning until December 2001, releasing persistent airborne contaminants across lower Manhattan.

Early reopening and long-term health consequences

Government authorities and commercial institutions expedited returns to the area while debris removal remained active. The New York Stock Exchange resumed trading on 17 September 2001, and the US Environmental Protection Agency stated on 18 September 2001 that the air was not harmful to human health. The environmental agency later retracted that safety evaluation after hundreds of thousands of workers, residents, and students returned to surrounding properties. Area schools reopened in early October 2001, leading numerous students to report respiratory difficulties shortly afterward. Lila Nordstrom, a student attending school near the site, developed severe asthma complications, acid reflux disease, and post-traumatic stress disorder. Twenty-five years after the catastrophe, tens of thousands of recovery personnel and residents suffer ongoing illnesses, with Andrews undergoing eight surgical procedures to remove skin cancers from his face, head, and chest.
