The events of Sept. 11, 2001 have had a long-lasting effect on Americans, who remember the day with sadness and horror. For some New Yorkers and others involved in the rescue and recovery efforts that day, the long-term health effects have been devastating.
An estimated 40,000 to 90,000 workers and volunteers were involved in some way in the rescue and recovery attempt and may have been affected by the dust. Respiratory illnesses have been especially prevalent.
Scientists have called the dust, smoke and ash unleashed by the destruction of the World Trade Center on 9/11 the greatest acute environmental disaster in New York City history [source: New York Times]. Fires burned at 1,000 degrees Fahrenheit (537.8 degrees Celsius), creating a toxic cloud that covered lower Manhattan and spread to neighboring areas, as well as to the outer boroughs.
