buildings showed low levels of asbestos on the floor of the lobby and
on
the ground outside. Results from the testing for other materials are
not yet complete but preliminary results indicate that fibrous glass
(fiberglass) was also present in settled dust samples.
Letters are being sent to building owners and residents informing them
of these findings and reminding them of DOH's cleaning recommendations.
Because work continues at the WTC site, residents and building owners
in
the area are advised to continue to follow cleanup instructions. These
include using a wet mop, damp cloth or a high efficiency particulate
air
filter (HEPA) vacuum to clean dust from hard surfaces. HEPA vacuums
should be used to clean carpets, upholstery, and other materials that
cannot be cleaned by wet wiping. To prevent the recirculation of dust,
residents were again advised not to sweep with "dry" brooms, use
dusters, or use vacuums without an approved HEPA filter. Additionally,
since work continues at the World Trade Center site, all residents were
advised to avoid carrying dust into their buildings from outdoors
(e.g.,
by taking off shoes, etc).
New York City Health Commissioner Thomas R. Frieden, MD, MPH said,
"Since the collapse of the World Trade Center, an event that resulted
in
the release of large amounts of dust and airborne substances, some
residents of lower Manhattan have experienced short-term health
problems
such as cough, irritation of the eyes, nose, and throat. The data from
air quality tests thus far have been reassuring. All of the testing
done
to date has not shown results that would indicate long-term health
impacts. However, conclusive scientific knowledge about the

potential health hazards of some substances is not available. It is not
possible to know with certainty whether there will be long-term health
consequences."
"DOH recognizes residents' concerns and will continue to work closely
with local, State and Federal agencies to monitor air quality and to
inform the public of findings as soon as results are available.
Additionally, DOH has been working with the U.S. Centers for Disease
Control and Prevention (CDC) to develop a protocol for a World Trade
Center Registry, which would generate and maintain a database that can
provide a more complete picture of short- and long-term health and
mental health impacts among the affected populations," Dr. Frieden
concluded.
The Sampling Plan
At the request of DOH, ATSDR conducted indoor air tests in 59
apartments in 30 geographically representative buildings in lower
Manhattan in November and December 2001. Testing was also conducted
in
four buildings above 59th Street not impacted by migrating dusts from
the World Trade Center site to provide information on the background
