9/11 dust linked to heart and lung damage: new study seeks answers
NCT ID NCT05215171
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how breathing in dust from the World Trade Center attacks may harm the heart and lungs of FDNY first responders. Researchers will measure certain substances in the blood and breathing tests to find early signs of disease. The goal is to better understand these health problems so doctors can diagnose and treat them sooner. About 100 retired or light-duty firefighters will take part.
