National Toxicology Program (NTP); National Institute of 
Environmental Health Sciences; NTP Announces the Release of the NTP 
Final Report From the Endocrine Disruptors Low-Dose Peer Review for 
Public Comment

Summary

    The National Toxicology Program (NTP)/National Institute of 
Environmental Health Sciences (NIEHS) organized and conducted a 
scientific peer review at the request of the US Environmental 
Protection Agency (EPA) to evaluate reported low-dose reproductive and 
developmental effects and dose-response relationships for endocrine 
disrupting chemicals. The NTP is soliciting public comment prior to 
transmitting the final report to the US EPA. Public comments received 
in response to this solicitation will be included in the final 
transmittal. The final report is available on the NTP web site at 
http://ntp-server.niehs.nih.gov or by contacting the NTP Office of 
Liaison and Scientific Review; 919-541-0530 (phone); 919-541-0295 
(fax); <a href="/cdn-cgi/l/email-protection#224e4b434b514d4c6251564350404351470c4c4b474a510c4c4b4a0c454d54"><span class="__cf_email__" data-cfemail="18747179716b7776586b6c796a7a796b7d3676717d706b36767170367f776e">[email protected]</span></a>; 111 T.W. Alexander Drive, P.O.

Background

    The NTP final report will be provided to the US EPA to help guide 
the agency in determining whether or not its guidelines for 
reproductive and developmental toxicity testing are adequate for 
endocrine active chemicals. For this meeting, ``low-dose effects'' 
referred to biological changes that occur in the range of human 
exposures or at doses lower than those typically used in the US EPA's 
standard testing paradigm for evaluating reproductive and developmental 
toxicity.
    The peer review included plenary sessions and several subpanel 
meetings. The peer review panel was divided into five subpanels: 
Bisphenol A, Other Environmental Estrogens and Estradiol, Androgens and 
Anti-Androgens, Biological Factors and Study Design, and Statistics and 
Dose-Response Modeling. The Panel examined data from major, selected 
studies (excluding studies on phthalates and dioxin and dioxin-like 
compounds) supporting the presence or absence of low-dose effects in 
laboratory animals that could be relevant for human health assessments. 
The Panel was also asked to evaluate the shape of the dose-response 
curve for endocrine active substances in the low-dose region. Prior to 
the peer review, members of the Statistics and Dose-Response Modeling 
Subpanel analyzed the raw data on selected parameters for 38 studies 
and provided its analyses to the other subpanels. At the peer review, 
members from this subpanel participated in other subpanels.
