time-weighted average for particulates.
VOCs - Sampling for volatile organic compounds (VOCs) was conducted on
October 11 in the smoke plume on the debris pile at ground zero. There was a
general increase in VOC levels, including benzene, compared to data collected on
Ob October 10. Benzene exceeded the OSHA time-weighted average permissible
■ exposure level at two locations in the smoke plume.
Dioxin - Ten samples were collected on September 27 and analyzed for
dioxin/furans. Two of the samples showed results above the guideline level at which
EPA would take some type of action to reduce people's exposure. This guideline
level assumes a 30-year exposure scenario. One of the samples (Location A at
WB West Broadway and Barclay) was nominally above the EPA guideline level when
adjusted to a 1-year exposure duration. These levels do not pose a short-term
health affect but should be monitored if they persist for a longer period of time. All
other locations had results that were generally lower than previous dioxin data
reported on September 16 and 23.
