Mayor releases 170,000 pages of 9/11 air‑toxicity records and settles lawsuits
Mayor Zohran Mamdani made public a trove of about 170,000 pages of New York City records that detail the city’s knowledge of toxic chemicals in Lower Manhattan and western Brooklyn after the September 11 attacks and the steps taken to limit liability. The release follows a settlement with the advocacy group 9/11 Health Watch and includes an internal October 2001 memo acknowledging the risks and potential lawsuits. At the same briefing, the mayor announced the settlement of two lawsuits that had restricted public access to the information. Federal health‑monitoring data show that 5,892 first responders and nearby residents have died from cancers linked to the dust, with 57,044 cancer cases recorded.
