Exposure to large quantities of known carcinogens released during the
September 11, 2001, collapse of the World Trade Center in New York City and
its subsequent cleanup apparently should have little effect on individuals
who lived or worked in the area, said researchers from the University of North
Carolina, Chapel Hill.
The researchers estimated that exposure to certain carcinogens released
at Ground Zero only added a one person per 100 million increase in lifetime
risk for individuals who lived or worked in the area. Their conclusions appeared
in an online edition of the Proceedings of the National
Academy of Sciences of the United States of America on July 27 (http://www.pnas.org/cgi/doi/10.1073/pnas.0404499101).
