* This reading exceeds the EPA benchmark. 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
Department of Health and Human Services' Web site.
