World Trade Center (WTC) Disaster
The World Trade Center (WTC) disaster sparked enormous concern about
the quality of the environment in the surrounding neighborhoods. One of the immediate
concerns was the effect of dust from the collapse of the towers on breathing, especially
in rescue workers and more susceptible individuals. Fine particulate matter (PM)
associated with dust from the crushed building materials may have unusual chemical
properties and health effects. These reports describe results of experiments conducted
by the Environmental Protection Agency which evaluated the chemistry and respiratory
toxicity of fine PM from WTC dust and contributed to the short-term health risk
assessment of WTC PM.
