airborne particles, some residents of lower Manhattan have reported short-tenn health problems
such as cough, and irritation of die eyes, nose, and throat The dau from air quality tests thus far
have been reassuring. None of the testing to date has shown results that would indicate long-term
health impacts. However, conclusive scientific knowledge about the potential health hazards of
some substances is not available. 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." Dr. Frieden continued.
“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, if funded, would generate
and maintain a database that can be used as a basis for conducting studies that can provide a more
complete picture of short- and long-term health and mental health impacts among the affected
populations,’’ Dr. Frieden concluded.
Sampling Summary
At the request of DOH, ATSDR conducted 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 59^ Street to provide information on the background level of
various substances present indoors in New York City. Using widely accepted testing methods, the
agency looked for several materials that are common building components or could potentially
cause short and long-term health problems. Each set of tests included samples of air and settled
dust, and these samples were analyzed for fiber-like materials - asbestos, fibrous glass - and for
other particles including silica, gypsum, mica, and calcite.
A total of 117 samples were taken from 30 buildings in lower Manhattan and analyzed for airborne
fibers. Samples were taken inside residences, in common areas within residential buildings, and
outside of the buildings. The air samples fiom inside the buildings showed no elevated levels of
asbestos. Levels were similar to those seen in areas not affected by the World Trade Center
collapse.
The analysis of 98 dust samples for asbestos taken from the inside and outside of residential
buildings in lower Manhattan indicated that while 20% were above background levels, only two
samples which were taken from outdoors required abatement Professional abatement work was
completed in this area.
Samples taken from inside and outside of residential buildings in lower Manhattan were analyzed
for fibrous glass. Fibrous glass was detected in 43 of the 98 samples taken. The results of air
sampling for fibrous glass, and for air and surface testing of other materials, are not yet available.
Health Information about Asbestos and Fiberglass
The risk of developing these diseases from environmental exposures depends on tire level and
duration of exposure.
Exposure to asbestos is associated with asbestosis (scarring of the lungs) and cancer. The likelihood
of developing disease from limited, short-term, low-level exposure is low. There is no reliable test
that can indicate whether an individual has had low-level exposures to asbestos. Tn the ficr-upaHnnal
