ATSDR will evaluate the quality and relevance of such data or studies for possible inclusion into the profile. ATSDR remains committed to providing a comment period for this document as a means to best serve public health.

The Superfund Amendments and Reauthorization Act of 1986 (SARA) [42 U.S.C. 9601 et seq.] amended the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA or Superfund) [42 U.S.C. 9601 et seq.] by establishing certain requirements for ATSDR and the U.S. Environmental Protection Agency (EPA) regarding hazardous substances that are most commonly found at facilities on the CERCLA National Priorities List (NPL). Among these statutory requirements is a mandate for the Administrator of ATSDR to prepare toxicological profiles for each substance included on the priority list of hazardous substances [also called the Substance Priority List (SPL)]. This list identifies 275 hazardous substances that ATSDR and EPA have determined pose the most significant potential threat to human health. The SPL is available online at​spl.

In addition, CERCLA provides ATSDR with the authority to prepare toxicological profiles for substances not found on the SPL. CERCLA authorizes ATSDR to establish and maintain inventory of literature, research, and studies on the health effects of toxic substances (CERCLA section 104(i)(1)(B)); to respond to requests for health consultations (CERCLA section 104(i)(4)); and to support the site-specific response actions conducted by the agency.

There have been two previous Public Comment periods for the Perfluoroalkyls toxicological profile, one in 2009 (74 FR 36492) and 2015 (80 FR 53157). Due to the public comments received to both notices, as well as new literature, we have revised the previous draft profile (including a revised Minimal Risk Level); therefore, ATSDR is releasing a revised draft profile for public comment.


The Draft Toxicological Profiles are available online at​ToxProfiles and at, Docket No. ATSDR-2015-0004.
