Category; studies (UC-Davis. ATSDR)
Q. Why did EPA not test for ultrafine particles, as were tested for in the UC Davis study?
EPA has been studying ultrafines over the past several years and there is not any scientific
evidence that links these ultra-fine particles - less than 1 micron in diameter - with health
effects. EPA continues to look at these particles and the additional information provided by the
UC Davis study will contribute to the growing body of knowledge about ultrafines.
Q. What additional work will be done on the ATSDR/DOH study? Will more apartments
be tested or will you retest the ones you already tested?
A. In addition. New York City Department of Health (NYCDOH), Agency for Toxic Substances
and Disease Registry (ATSDR), and EPA are planning to build on the indoor air study conducted
in November and December 2001. This may include followup monitoring or recommendations
for further cleaning.
Category; database
Q. What is the status of the database? Have you seen any trends yet? What sub
populations are you looking at e.g., workers in the building at the time of the impacts,
cleanup workers, children living in the area?
A. EPA has developed a database that houses data from all agencies and are in the process of
making this system available to the public (ARE WE?). EPA data can be obtained fi-om or
website and other agencies also have their data posted on their web sites. From our review of the
data, in the long term - EPA does not anticipate any increased risk from exposure to WTC
material for residents and office workers from the ambient air. Removing the dust from within
your apartment and from your building will reduce any risk that may exist from the indoor
apartment. We have continuously informed workers at the WTC site to wear respiratory
protection to reduce their risks of exposure to contaminants from the site. In the short term -
individuals have experienced irritation and a worsening of existing respiratory conditions due to
the WTC dust.
Q. Who can explain what the data means?
A. EPA has professional staffers who can explain the data. If you call our Asbestos hotline or
the Superfund ombudsman in Region 2, your questions can be answered. (Do we want to send
people to the asbestso hotline - do they know about WTC?)
