Candidate Chemicals for Possible Inclusion in Future Releases of
the National Report on Human Exposure to Environmental Chemicals


Note from FAN:
CDC's January 2003 "Second National Report on Human Exposure
to Environmental Chemicals
" is also available at
http://www.fluoridealert.org/pesticides/cdc.exposure.report.jan2003.pdf

The Selection Criteria as published in the Oct 7, 2002, Federal Register:

(1) Independent scientific data which suggest that the
potential for exposure of the U.S. population to a particular
chemical is changing (i.e., increasing or decreasing) or persisting;

(2) seriousness of health effects known or suspected to result from
exposure to the chemical (for example, cancer, birth defects, or other
serious health effects);

(3) proportion of the U.S. population likely to be exposed to
levels of chemicals of known or potential health significance;

(4) need to assess the efficacy of public health actions to reduce
exposure to a chemical in the U.S. population or a large component
of the U.S. population (for example, among children, women of
childbearing age, the elderly);

(5) existence of an analytical method that can measure the chemical
or its metabolite in blood or urine with adequate accuracy, precision,
sensitivity, specificity, and speed;

(6) incremental analytical cost (in dollars and personnel) to perform
the analyses (preference is given to chemicals that can be added
readily to existing analytical methods).

Candidate Chemicals for Possible Inclusion in Future Releases of
the National Report on Human Exposure to Environmental Chemicals
AGENCY: Centers for Disease Control and Prevention (CDC), Health and
Human Services (HHS).

ACTION: On Monday, October 7, 2002, CDC published final selection
criteria and solicited nominations for chemicals or categories of
chemicals for analytical development and inclusion in future releases
of the National Report on Human Exposure to Environmental Chemicals
(the ``Report''). (See 67 FR, p. 62477-8, October 7, 2002.)
Subsequently, the nominated chemicals were published on CDC's Web site,
<A HREF="http://frwebgate.access.gpo.gov/cgi-bin/leaving.cgi?from=leavingFR.html&log=linklog&to=http://www.cdc.gov/exposurereport">http://www.cdc.gov/exposurereport</A>. CDC now provides the list of
candidate chemicals by priority groups that may be included in future
releases of the ``Report.'' Using the selection criteria and the
weighting factors described in the above-mentioned notice, an expert
panel of outside reviewers and scientists at CDC's National Center for
Environmental Health, Division of Laboratory Sciences, scored nominated
individual chemicals or categories of chemicals.
On the basis of their
final point score, chemicals were placed in one of five priority
groups.
Listing these chemicals or categories of chemicals in priority
groups does not imply that CDC has determined that exposure to them
causes adverse human health effects. The nominations enabled CDC to
learn which chemicals or categories concerned the public and the
scientific community. Chemicals in the priority groups are listed in
alphabetical order. Chemicals in Group 1 are more likely, but not
guaranteed, to appear in future releases of the ``Report'' than are
chemicals in the remaining groups
. In addition to appearing in the
Federal Register, the list of candidate chemicals will appear on CDC's
Web site at <A HREF="http://frwebgate.access.gpo.gov/cgi-bin/leaving.cgi?from=leavingFR.html&log=linklog&to=http://www.cdc.gov/exposurereport/candidatechemicals">http://www.cdc.gov/exposurereport/candidatechemicals</A>. CDC
will publish additional notices in the Federal Register as needed to
keep the public abreast of progress.

SUPPLEMENTARY INFORMATION: CDC publishes the ``Report'' under the
authorities 42 U.S.C. 241 and 42 U.S.C. 242k. The ``Report'' provides
an ongoing assessment using biomonitoring of the exposure of the
noninstitutionalized, U.S. civilian population to environmental
chemicals. Biomonitoring assesses human exposure to chemicals by
measuring the chemicals or their breakdown products in human specimens
such as blood or urine. For the ``Report,'' an environmental chemical
means a chemical compound or chemical element present in air, water,
soil, dust, food, or other environmental medium. The ``Report''
provides exposure information about participants in an ongoing national
survey known as the National Health and Nutrition Examination Survey
(NHANES). This survey is conducted by CDC's National Center for Health
Statistics; biomonitoring measurements are conducted by CDC's National
Center for Environmental Health. The first ``Report,'' published in
March 2001, gave information about levels of 27 chemicals in the U.S.
population. The second ``Report,'' published in January 2003, provided
data on 116 chemicals, including expanded data on the 27 in the first
``Report,'' and was the most extensive assessment ever of the exposure
of the U.S. population to environmental chemicals. The ``Report'' can
be obtained in the following ways: Access <A HREF="http://frwebgate.access.gpo.gov/cgi-bin/leaving.cgi?from=leavingFR.html&log=linklog&to=http://www.cdc.gov/exposurereport">http://www.cdc.gov/exposurereport</A>; e-mail <A HREF="mailto:ncehdls@cdc.gov">ncehdls@cdc.gov</A>; or telephone 1-866-670-6052.
Current plans are to release future reports of exposure of the U.S.
population that cover 2-year periods (e.g., 2001-2002; 2003-2004; 2005-
2006) and that will include data on more chemicals than the 116 listed
in the second ``Report.'' Over time, CDC will be able to track trends
in exposure levels. Future releases also may include additional
exposure information for special exposure populations (e.g., children,
women of childbearing age, elderly people) from studies examining
localized or point sources and from studies of adverse health effects
resulting from exposure to varying levels of environmental chemicals.
The Director, Management Analysis and Services Office, has been
delegated the authority to sign Federal Register <strong>notices</strong> pertaining to
announcements of meetings and other committee management activities for
both the CDC and ATSDR.
