The expert panel will meet on June 1-3, 2005, at the Holiday Inn Old Town Select in Alexandria, Virginia to review and revise the draft expert panel report and reach conclusions regarding whether exposure to styrene is a hazard to human development or reproduction. The expert panel will also identify data gaps and research needs. CERHR expert panel meetings are open to the public with time scheduled for oral public comment. Attendance is limited only by the available meeting room space. Following the expert panel meeting and completion of the expert panel report, the CERHR will post the report on its Web site and solicit public comment on it through a Federal Register notice.

Styrene (ethenylbenzene; CAS RN: 100-42-5) is a high production volume chemical used in the production of polystyrene resins and as a co-polymer with acrylonitrile and 1,3-butadiene. Styrene is found in items such as foam cups, dental fillings, matrices for ion exchange filters, construction materials, and boats. It is also used in protective coatings, reinforced glass fiber, agricultural products, and as a food additive. The public can be exposed to styrene by ingesting food or drink that has been in contact with styrene polymers or through inhalation of polluted air and cigarette smoke. CERHR selected styrene for expert panel evaluation because of: (1) Public concern about styrene exposure and (2) recently available exposure studies.
At the expert panel meeting, the expert panel will review and revise the draft expert panel report and reach conclusions regarding whether exposure to styrene is a hazard to human reproduction or development. Each draft expert panel report has the following sections:
1.0 Chemistry, Use, and Human Exposure
2.0 General Toxicological and Biological Effects
3.0 Developmental Toxicity Data
4.0 Reproductive Toxicity Data
5.0 Summary, Conclusions, and Critical Data Needs (to be prepared at expert panel meeting)
Request for Comments
The CERHR invites written public comments on sections 1-4 of the draft expert panel report on styrene. Any comments received will be posted on the CERHR Web site prior to the meeting and distributed to the expert panel and CERHR staff for their consideration in revising the draft report and preparing for the expert panel 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 2.
Time is set-aside on June 1, 2005, 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, also send a copy of the statement or talking points to Dr. Shelby by May 25. 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 June 1, 2005, from 7:30-8:30 a.m. Those 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.
The meeting begins each day at 8:30 a.m. On June 1 and 2, it is anticipated that a lunch break will occur from noon-1 p.m. and the meeting will adjourn at 5-6 p.m. The meeting is expected to adjourn by noon on June 3; however, adjournment may occur earlier or later depending upon the time needed by the expert panel to complete its work.

Background Information on the CERHR
The NTP established the NTP CERHR in June 1998 [Federal Register, December 14, 1998 (Volume 63, Number 239, page 68782)]. The 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.
The 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). The CERHR selects chemicals for evaluation based upon several factors including production volume, extent of human exposure, public concern, and published evidence of reproductive or developmental toxicity.
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 the CERHR.Start Signature
