New York City releases 170,000 documents on post-9/11 toxic air exposure

9/11 air quality toxic exposure New York City government declassified documents World Trade Center Health Program

New York City Mayor Zohran Mamdani has announced the release of over 170,000 pages of previously undisclosed documents concerning air quality and health risks following the September 11, 2001, attacks. The release, which follows a legal settlement with the advocacy group 9/11 Health Watch, suggests that multiple successive mayoral administrations withheld information regarding toxic chemical exposure in Lower Manhattan and Western Brooklyn from the public, Congress, and the City Council.

The documents indicate that city officials were aware of dangerous levels of substances such as asbestos and benzene around Ground Zero shortly after the attacks, yet continued to message that the air was ‘safe and acceptable.’ This discrepancy has been linked to long-term health consequences; a federal monitoring program reports that more than 9,400 people have died from illnesses related to the exposure. Mayor Mamdani noted that the number of deaths from 9/11-related illnesses has now surpassed the number of people killed during the initial attacks.

The city has allocated $34 million to maintain a public portal for these records. The release comes ahead of the 25th anniversary of the attacks and aims to provide accountability for the city's response. The World Trade Center Health Program, which has enrolled over 140,000 people, continues to assist thousands of survivors and responders facing chronic illnesses, including cancer.
