World Trade Center (WTC) Disaster

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.
