CERCLA Priority List of Hazardous Substances for 2001
What is the Top 20 List?
The list below contains the Top 20 hazardous substances on the CERCLA Priority List of Hazardous Substances for 2001. The complete list of 275 substances is obtained from an annual evaluation fulfilling the conditions of CERCLA section 104 (i), as amended, which requires ATSDR and EPA to revise the Priority List of Hazardous Substances periodically to include additional hazardous substances.
Further information about the evaluation process and the complete set of 275 substances on the current list can be accessed online at:
CERCLA Priority List of Hazardous Substances for 2001.
Each of the Top 20 substances listed below is identified with their 2001 Rank Number and includes a link to an ATSDR publication, the ToxFAQs^- Sheet, which has further health and chemical information about that substance.
The ATSDR Division of Toxicology has prepared several sets of publications that provide answers to many health concerns that are voiced by community groups and give general information on various properties of each of these substances. Those publications are listed and may be accessed online at:

What is the CERCLA List?
The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) section 104 (i), as amended by the Superfund Amendments arid 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 CERCLA priority list is revised and published on a 2-year basis, with a yearly informal review and revision. Each substance on the CERCLA Priority List of Hazardous Substances is a candidate to become the subject of a toxicological profile prepared by ATSDR and subsequently a candidate for the identification of priority data needs. This priority list is based on an algorithm that utilizes the following three components: frequency of occurrence at NPL sites, toxicity, and potential for human exposure to the substances found at NPL sites. This algorithm utilizes data from ATSDR's HazDat database, which contains information from ATSDR's public health assessments and health consultations.
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.
