# SUPPLEMENTARY INFORMATION:

## Background 

                    CERHR convened the first expert panel meeting on March 5-7 in Alexandria, VA to assess the potential reproductive and developmental hazards of bisphenol A. The panel discussed the scientific evidence and made revisions to the draft expert panel report on bisphenol A, but because of the length and complexity of this evaluation, the panel was unable to complete its task (a meeting summary is available at                     *http://cerhr.niehs.nih.gov/​chemicals/​bisphenol/​bisphenol.html*).                 

The expert panel will reconvene on May 21-23, 2007, for a second meeting. The meeting location, which is not yet set, will be posted on the CERHR Web site when finalized along with a schedule for the meeting. The meeting will begin each day at 8:30 a.m. and continue until adjournment. It is expected to adjourn by noon on May 23, although adjournment may occur earlier or later depending upon the time needed for the expert panel to complete its work. The expert panel will (1) continue its review, (2) finalize sections 1-4 of the draft report, (3) reach conclusions regarding whether exposure to bisphenol A is a hazard to human reproduction or development, and (4) write Section 5 Summary, Conclusions, and Critical Data Needs. 

At the March meeting, working groups for sections 1-4 of the draft report met periodically to discuss their sections and prepare materials for deliberation by the panel during public plenary sessions. The working groups for Section 3 Developmental Toxicity Data and Section 4 Reproductive Toxicity Data will meet on April 5-6 in Durham, NC to continue discussions not completed at the March meeting. Their edits will be included in the interim draft expert panel report, which will be posted on the CERHR Web site and available for public comment by April 20, and brought before the expert panel during the public plenary sessions at the May 21-23 meeting. 

The interim draft report, which will show all edits to date, will be posted on the CERHR Web site by April 20 and serve as the starting point for the panel's discussions at its May meeting. 

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. 

## Request for Comments 

                    The CERHR invites written public comments on the interim draft expert panel report on bisphenol A. Any comments received will be posted on the CERHR Web site prior to the second meeting and distributed to the expert panel and CERHR staff for their consideration in revising the draft report and/or preparing for the second meeting. 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) and send them to Dr. Shelby (see                     **ADDRESSES**                     above) for receipt by May 14, 2007.                 

Time will be set-aside on May 21, 2007, for the presentation of oral public comments at the expert panel meeting. Seven minutes will be available for each speaker (one speaker per organization). When registering to comment orally, please provide your name, affiliation, mailing address, telephone and facsimile numbers, e-mail and sponsoring organization (if any). If possible, send a copy of the PowerPoint slides, statement, or talking points to Dr. Shelby by May 14. This statement will be provided to the expert panel to assist them in identifying issues for discussion and will be noted in the meeting record. Registration for presentation of oral comments will also be available at the meeting on May 21, 2007, from 7:30-8:30 a.m. Persons registering at the meeting are asked to bring 20 copies of their statement or talking points for distribution to the expert panel and for the record. 

## Background Information on CERHR 

                    NTP established CERHR in June 1998 [                    **Federal Register**                    , December 14, 1998 (Volume 63, Number 239, page 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 the 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 homepage (                    *http://cerhr.niehs.nih.gov*) or by contacting Dr. Shelby (see                     **FOR FURTHER INFORMATION CONTACT**                     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. The formal evaluation process was published in the                     **Federal Register**                     on July 16, 2001 (Volume 66, Number 136, pages 37047-37048) and is available on the CERHR Web site under “About CERHR” or in printed copy from CERHR.
