On September 11, 2001, attacks on the World Trade Center towers released a dust cloud containing pulverized cement, glass fiber, and asbestos, among other toxins – marking the health of thousands of community members and first responders. Twenty-five years later, New York City has announced it will finally release the full records on the day’s health impact.

In a statement released by the city administration, Manhattan Borough officials emphasized the dust and smoke to which first responders were exposed to contained over 2,500 contaminants and faced long-term health consequences, including respiratory illnesses and cancers.

“For 25 years, four different Mayoral administrations kept from the public, the US Congress, and the City Council documents showing what the City actually knew about the danger of the toxic chemicals in Lower Manhattan and Western Brooklyn after the World Trade Center collapse, even as City officials continued messaging to the public that the air was ‘safe and acceptable,’” the organization 9/11 Health Watch stated on September 8.

The risks posed by the contamination were known from the very beginning, given the date of the towers’ construction and the materials used at the time. From health professionals to left-wing activists, many emphasized the hazardous potential of the dust and insisted the effects could not be resolved in a matter of days. Despite these warnings, local health structures and administration assured people of air safety in affected areas as early as a week later – and did not change course even as their own analyses indicated elevated levels of toxic elements like lead.

City officials saw survivors as liabilities, documents show

Newly released documents expose that city officials were aware of the health risks posed by the toxic dust, yet they prioritized minimizing financial threats to the city budget. One of the related documents, the Harding memo, shows that by October 2001 the City feared it could face over 10,000 claims as a result of its health advice.

Official reassurances to residents that it was safe to return to their homes too early contributed to thousands of people, including children, experiencing symptoms like rashes, heavy coughs, and nosebleeds, leaving them exposed to long-term health impacts.

The memo clearly indicates that city officials knew community members might realize official advisories led them to return to the impact area too soon – “causing toxic exposure or emotional harm” – and that rescue workers could complain they “were provided with faulty equipment or no equipment (i.e. respirators).”

Among the workers most exposed to the pollution were cleanup and recovery officers, along with members of the police and fire departments. Firefighters were particularly affected. Several reports over the years recorded the evolving health conditions they contracted as a result, including lung diseases, sarcoidosis, several types of cancer, and mental health issues. While some of these impacts could have been minimized by wearing appropriate gear, many of those arriving first relied on basic dust masks. “Respirators, which provide the actual protection needed, were seldom used on 9/11 and in the early days,” the Fire Department’s 2026 report notes.

“Firefighters described walking through dense clouds of dust and smoke in the hours immediately after the attack, in which ‘the air was thick as soup,’” a 2004 study pointed out. “FDYN responders inhaled this thick, polluted air,” the Fire Department also noted, “a situation made worse by the strenuous work that required increased respiratory effort and open-mouth breathing.”

Post-9/11 health landscape still evolving

With many conditions caused by the substances present in the dust taking decades to develop, the post-9/11 health landscape is still evolving – requiring ongoing monitoring and care. Despite leading to hundreds of additional deaths and chronic conditions, these cases have seen significantly less interest compared to the deaths caused directly by the attack on the WTC towers.

The absence of a public healthcare system in the US also meant that 9/11 survivors could not automatically count on receiving the care they need. This is only one of the consequences of a system where health is treated as a commodity, as emphasized by socialist health professionals and activists. In 2006, one of these analysts, Vicente Navarro, pointed out that thousands of preventable deaths occurring each year in the US are directly linked to the lack of a strong public health system.

“The number depends on how one defines ‘preventable deaths,’” he wrote. “But even the conservative figure of 18,000 deaths per year is six times the number of people killed in the World Trade Center on 9/11. That event outraged people (as it should), but the deaths resulting from lack of health care seem to go unnoticed.”
