On September 11, 2001, nearly 3,000 people lost their lives in one of the most devastating attacks in American history. Twenty-five years later, we continue to honor those who were killed, the first responders who rushed toward danger, and the families forever changed by that day. But the effects of 9/11 did not end when the dust settled.
When the World Trade Center towers collapsed, enormous clouds of dust spread across Lower Manhattan. According to the CDC, the debris contained asbestos, silica, concrete, glass fibers, lead, and other potentially harmful substances. Fires at Ground Zero continued burning for months, creating additional exposure to smoke and pollutants.
The CDC estimates that around 400,000 people were exposed to contaminants and other hazardous conditions following the attacks. First responders, cleanup workers, residents, office workers, and students were among those affected. In the years since, exposure to the World Trade Center environment has been associated with respiratory illnesses, cancers, and other health conditions.
Twenty-five years later, researchers are still trying to understand the full impact. A new major study will focus on people who were children—or even still in the womb—during 9/11 and were exposed near Ground Zero. About 25,000 children lived or attended school near the World Trade Center at the time.
The environmental legacy of 9/11 reminds us that the consequences of a disaster can last far beyond the event itself. Protecting air quality, understanding toxic exposure, and providing accurate environmental information during emergencies can affect public health for decades
