DEPARTMENT OF HEALTH AND HUMAN SERVICES
National Toxicology Program (NTP); Center for the Evaluation of
Risks to Human Reproduction (CERHR); Announcement of the Availability
of the Bisphenol A Expert Panel Report; Request for Public Comment
AGENCY: National Institute of Environmental Health Sciences (NIEHS);
National Institutes of Health (NIH).
ACTION: Announcement of report availability and request for comment.
-----------------------------------------------------------------------
SUMMARY: CERHR announces the availability of the final bisphenol A
expert panel report on November 26, 2007, from the CERHR Web site
(http://cerhr.niehs.nih.gov) or in print from CERHR (see ADDRESSES
below). The expert panel report is an evaluation of the reproductive
and developmental toxicity of bisphenol A conducted by an independent,
12-member expert panel composed of scientists from the public and
private sectors convened by CERHR. CERHR invites the submission of
public comments on this report (see SUPPLEMENTARY INFORMATION below).
The expert panel met twice in public session (March 5-7, 2007 and
August 6-8, 2007) to review and revise the draft expert panel report
and reach conclusions regarding whether exposure to bisphenol A is a
hazard to human development or reproduction. The expert panel also
identified data gaps and research needs.
DATES: The final bisphenol A expert panel report will be available for
public comment on November 26, 2007. Written public comments on this
report should be received by January 25, 2008.
ADDRESSES: Comments on the expert panel report and any other
correspondence should be sent to Dr. Michael D. Shelby, CERHR Director,
NIEHS, P.O. Box 12233, MD EC-32, Research Triangle Park, NC 27709, fax:
(919) 316-4511, or e-mail: shelby@niehs.nih.gov. Courier address:
CERHR, 79 T.W. Alexander Drive, Building 4401, Room 103, Research
Triangle Park, NC 27709.

Background
Bisphenol A (CAS RN: 80-5-07) is a high production volume chemical
used in the production of epoxy resins, polyester resins, polysulfone
resins, polyacrylate resins, polycarbonate plastics, and flame
retardants. Polycarbonate plastics are used in food and drink
packaging; resins are used as lacquers to coat metal products such as
food cans, bottle tops, and water supply pipes. Some polymers used in
dental sealants and tooth coatings contain bisphenol A. Exposure to the
general population can occur through direct contact to bisphenol A or
by exposure to food or drink that has been in contact with a material
containing bisphenol A. CERHR selected this chemical for evaluation
because of (1) high production volume, (2) widespread human exposure,
(3) evidence of reproductive toxicity in laboratory animal studies, and
(4) public concern.
The CERHR convened an expert panel on March 5-7, 2007, and on
August 6-8, 2007, to review and revise the draft and interim draft
expert panel reports and reach conclusions regarding whether exposure
to bisphenol A is a hazard to human development or reproduction. The
expert panel also identified data gaps and research needs. CERHR
solicited public comments on drafts of the expert panel report several
times (FR, December 12, 2006, Vol. 71, No. 238 pp. 74534-74536; FR,
April 2, 2007, Vol. 72, No. 62 pp. 15695-15696; FR, May 1, 2007, Vol.
72, No. 83 pp. 23833-23834).
Following receipt of public comments on the final bisphenol A
expert panel report, CERHR staff will prepare the NTP-CERHR monograph.
NTP-CERHR monographs are divided into four major sections: (1) The NTP
Brief that provides the NTP's interpretation of the potential for the
chemical to cause adverse reproductive and/or developmental effects in
exposed humans, (2) a roster of expert panel members, (3) the final
expert panel report, and (4) public comments received on that report.
The NTP Brief is based on the expert panel report, public comments on
that report, public and peer review comments on the draft NTP Brief,
and any new, relevant information that becomes available after the
expert panel meetings.
Request for Comments
CERHR invites written public comments on the bisphenol A expert
panel report. Written comments should be sent to Dr. Michael Shelby
(see ADDRESSES above). Persons submitting written comments are asked to
include their name and contact information (affiliation, mailing
address, telephone and facsimile numbers, e-mail, and sponsoring
organization, if any). Any comments received will be posted on the
CERHR Web site and included in the NTP CERHR monograph on this
chemical. All public comments will be considered by the NTP during
preparation of the NTP Brief (see ``Background'' above).
Background Information on CERHR
The NTP established the CERHR in June 1998 [FR, December 14, 1998
(Vol. 63, No. 239, pp. 68782)]. CERHR is a publicly accessible resource
for information about adverse reproductive and/or developmental health
effects associated with exposure to environmental and/or occupational
exposures. Expert panels conduct scientific evaluations of agents
selected by CERHR in public forums.
CERHR invites the nomination of agents for review or scientists for
its expert registry. Information about CERHR and the nomination process
can be obtained from its Web site (http://cerhr.niehs.nih.gov) or by
contacting Dr. Shelby (see ADDRESSES above). CERHR selects chemicals
for evaluation based upon several factors including production volume,
potential for human exposure from use and occurrence in the
environment, extent of public concern, and extent of data from
reproductive and developmental toxicity studies.
CERHR follows a formal, multi-step process for review and
evaluation of selected chemicals. A description of the evaluation
process is available on the CERHR Web site under ``About CERHR'' or in
printed copy from CERHR.
