SUPPLEMENTARY INFORMATION:

This draft toxicological profile for perfluoroalkyls was prepared in accordance with guidelines developed by the Agency for Toxic Substances and Disease Registry and the Environmental Protection Agency (EPA) for the preparation of toxicological profiles. The original guidelines were published in the Federal Register on April 17, 1987. While perfluoroalkyls are not found on the ATSDR Priority List of Hazardous Substances, ATSDR has determined that a profile for these substances was necessary because data indicate that some perfluoroalkyls are found in the blood of the United States general population and in the environment. The agency also determined that it was important to characterize the current available information regarding the health effects from exposure to perfluoroalkyls in order to support and inform public health responses and activities by ATSDR and others. This profile will be revised and republished as necessary.

Section 104(i)(3) of the Comprehensive Environmental Response, Compensation, and Liability Act [42 U.S.C. 9604(i)(3)] outlines the content of the toxicological profiles. Each profile includes an examination, a summary, and an interpretation of available toxicological information and epidemiologic evaluations. This information and these data are to be used to identify the levels of significant human exposure to a substance and the associated health effects. The profiles must also include a determination of whether adequate information on the health effects of each substance is available or in the process of development. When adequate information is not available, ATSDR, in cooperation with the National Toxicology Program (NTP), will initiate a research program to determine these health effects.

Although key studies for this substance were considered during the profile development process, this Federal Register notice solicits any additional studies, particularly unpublished data and ongoing studies, which will be evaluated for possible addition to the profile now or in the future.Start Printed Page 36493

The following draft toxicological profile will be made available to the public on or about July 6, 2009.

All profiles issued as “Draft for Public Comment” represent ATSDR's best efforts to provide important toxicological information on priority substances. We are seeking public comments and additional information that may be used to supplement this profile. ATSDR remains committed to providing a public comment period for these documents as the best means to serve public health and our clients.
