Independent Panel Evaluates Potential Health Risks of Bisphenol A

National Institute of Environmental Health Sciences (NIEHS)

News Release

Monday, July 30, 2007, 12:00 p.m. EDT
Contact: Robin Mackar, NIEHS




An independent panel of scientists convened by the Center for the Evaluation of Risks to Human Reproduction (CERHR) of the National Toxicology Program (NTP) will review recent scientific data and expects to reach conclusions regarding whether or not exposure to a widely used chemical, Bisphenol A (BPA) is hazardous to human development or reproduction. The NTP is located in Research Triangle Park, North Carolina, at the National Institute of Environmental Health Sciences (NIEHS), one of the National Institutes of Health.

The expert panel met in March, 2007 and worked for 2.5 days to review and assess the more than 500 scientific BPA-related studies cited in the report. Because of the length and complexity of this evaluation, the panel was unable to complete its review and has scheduled this second meeting to review and revise the draft expert panel report at and write its summary, conclusions and critical data needs.

Details about the meeting, including panel roster and public comments, are posted on the NTP website at The 2.5 day meeting is open to members of the public and the media.


August 6, 8:30 a.m. – 5:00 p.m. (Time is set aside on the morning of August 6th for oral public comments, limited to seven minutes per speaker or organization)
August 7, 8:00 a.m. – 5:00 p.m.
August 8, 8:00 a.m. – noon
(The expert panel meeting may end earlier or later each day, depending on when the panel completes its deliberations.)

Press Availability: Immediately following the meeting on Wednesday, August 8, 2007.

Members of the media interested in attending the meeting, the press availability immediately following the meeting, or arranging phone interviews with the panel Chair or with CERHR staff, please contact Robin Mackar at 984-287-3355 or by email at

Bisphenol A (BPA) is a high production volume chemical used in the production of polycarbonate plastic and several types of resins. Polycarbonate plastics are widely used in a variety of products including food and drink containers, CDs, DVDs, electrical and electronic equipment, automobiles, sports safety equipment. Resins are used as a protective lining in metal food and drink containers and water supply pipes. In vitro and animal data indicate that BPA may mimic the natural female sex hormone, estradiol. Exposure to the general population can occur through direct contact to BPA or by exposure to food or drink that has been in contact with material containing BPA.

The Center for the Evaluation of Risks to Human Reproduction (CERHR) selected this compound for evaluation because of its high volume of production, widespread human exposure, evidence of reproductive toxicity in animal studies, and public interest and concern.


The CERHR was established by the National Institute of Environmental Health Sciences (NIEHS) as part of the National Toxicology Program in 1998. Michael Shelby, Ph.D., serves as the CERHR Director. CERHR convenes a scientific expert panel that meets in a public forum to review, discuss, and evaluate the scientific literature on a selected chemical.

CERHR selects chemicals for evaluation based upon several factors including production volume, extent of human exposure, public concern, and the extent of published information from reproductive and developmental toxicity studies. The NTP is a Department of Health and Human Services program established in 1978. It is headquartered at the NIEHS, a part of the National Institutes of Health. The NIEHS Director, David A. Schwartz, M.D., serves as the NTP Director.
