# SUPPLEMENTARY INFORMATION:

ATSDR has prepared drafts of two updated toxicological profiles based on current understanding of the health effects and availability of new studies and other information since their initial release. All toxicological profiles issued as “Drafts for Public Comment” represent the result of ATSDR's evidence-based evaluations of the available literature to provide important toxicological information on priority hazardous substances to the public and health professionals. ATSDR considers key studies for these substances during the profile development process, using a systematic review approach. To that end, ATSDR is seeking public comments and additional information or reports on studies about the health effects of these substances for review and potential inclusion in the profiles. ATSDR will evaluate the quality and relevance of such data or studies for possible inclusion in the profile.

## Legislative Background

                    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 the hazardous substances most commonly found at facilities on the CERCLA National Priorities List. 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 has determined pose the most significant potential threat to human health. The SPL is available online at                     *http://www.atsdr.cdc.gov/​SPL.*                     ATSDR is also mandated to revise and publish updated toxicological profiles, as necessary, to reflect updated health effects and other information.                

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 an inventory of literature, research, and studies on the health effects of toxic substances (CERCLA Section 104(i)(1)(B); 42 U.S.C. 9604(i)(1)(B)); to respond to requests for health consultations (CERCLA Section 104(i)(4); 42 U.S.C. 9604(i)(4)); and to support the site-specific response actions conducted by the agency (CERCLA Section 104(i)(6); 42 U.S.C. 9604(i)(6)).

ATSDR has now prepared drafts of two updated toxicological profiles based on current understanding of the health effects and availability of new studies and other information since their initial release.

## Availability

                    The draft toxicological profiles and interaction profile are available online at                     *http://www.regulations.gov,*                     Docket No. ATSDR-2023-0005 and at                     *http://www.atsdr.cdc.gov/​ToxProfiles.*
