The 25th anniversary of the tragedy in New York is being commemorated, with the attack on the Twin Towers. Since then, there has been a prolonged debate about the effects of the towers' collapse on the city's air quality.
The most recent data points to more than 9,000 deaths related to exposure to toxic materials released during the buildings' collapse.
This number represents the long-term public health consequences resulting from the disaster of September 11, 2001.
