* This reading exceeds the EPA level of concern. It may not indicate increased risk,
however, because these are "snapshots," rather than long-term exposure
measurements. Weather and recovery activities at the World Trade Center can
cause temporary variations in asbestos levels that affect these snapshots.
Best estimate: no flow information available
DUP - indicates that more than one sample was taken at a particular time; all values
are reported.
There may be gaps in daily readings because of relocated construction equipment
and variations in sampling locations.
For more information about asbestos, see the fact sheet ■■■i from the
Department of Health and Human Services' Web site.
