ATSDR Toxic Substances Update

ATSDR Toxic Substances Update

CDC

Intent to develop Set 30 Toxicological Profiles to include:

Agency for Toxic Substances & Disease Registry

The Priority List of Hazardous Substances That Will Be the Candidates for Toxicological Profiles

What is the Substance Priority List (SPL)?
The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) section 104 (i), as amended by the Superfund Amendments and Reauthorization Act (SARA), requires ATSDR and the EPA to prepare a list, in order of priority, of substances that are most commonly found at facilities on the National Priorities List (NPL) and which are determined to pose the most significant potential threat to human health due to their known or suspected toxicity and potential for human exposure at these NPL sites. CERCLA also requires this list to be revised periodically to reflect additional information on hazardous substances.
This substance priority list is revised and published on a 2-year basis, with a yearly informal review and revision. (No list was published in 2009 while ATSDR transitioned to a new agency science database.) Each substance on the list is a candidate to become the subject of a toxicological profile prepared by ATSDR. The listing algorithm prioritizes substances based on frequency of occurrence at NPL sites, toxicity, and potential for human exposure to the substances found at NPL sites.
It should be noted that this priority list is not a list of "most toxic" substances, but rather a prioritization of substances based on a combination of their frequency, toxicity, and potential for human exposure at NPL sites.
Thus, it is possible for substances with low toxicity but high NPL frequency of occurrence and exposure to be on this priority list. The objective of this priority list is to rank substances across all NPL hazardous waste sites to provide guidance in selecting which substances will be the subject of toxicological profiles prepared by ATSDR.
Where can I find more information on the Substance Priority List?
There is a Support Document to the Priority List of Hazardous Substances that describes in detail how the list is developed. There is also a Detailed Data Table showing the breakdown of the total scores for each substance on the priority list. These documents and other supporting information are available on the Substance Priority List Resource Page.
