The current TRI toxic chemical list contains 581 individually listed chemicals and 30 chemical categories (including 3 delimited categories containing 58 chemicals). If the members of the three delimited categories are counted as separate chemicals then the total number of chemicals and chemical categories is 666 (i.e., 581 + 27 + 58).
TRI Chemical Lists
Note: Three chemicals on the current list (methyl mercaptan,
hydrogen sulfide, and 2,2-dibromo-3-nitrilopropionamide) are under administrative
stays and are not currently reportable.

TRI Chemical List Changes (1987- 2005)
- TRI Chemical List Changes (PDF) (11 pp, 163K, About
PDF)
EPA has made chemical list changes through the chemical petitions process and EPA-initiated review, therefore, the TRI list of reportable toxic chemicals can vary from year to year. This document lists all the additions and deletions to the TRI chemical list and indicates the first or last reporting year for the listed chemical. For information about the toxic effects of some of the TRI chemicals, see Toxicity Information, and for lists of regulations that cover some TRI chemicals, see Regulatory Program information.
Regulatory Program Information
- TITLE III List
of Lists (PDF) (105 pp, 5.3 MB, About
PDF)
This is a consolidated list of chemicals subject to reporting requirements under Title III of the Superfund Amendments and Reauthorization Act of 1986 (SARA) with references to their reporting status under Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund), The Resource Conservation and Recovery Act (RCRA), and Sections 302 and 313 of The Emergency Planning & Community Right-To-Know Act (EPCRA).
- Regulatory Matrix of TRI Chemicals in other
Federal Programs (PDF) (9 pp, 183K, About
PDF)
A matrix has been developed for each TRI chemical indicating whether it is regulated under other selected environmental laws.
Toxicity Information
- Hazard Information on Toxic Chemicals Added
to EPCRA Section 313 Under Chemical Expansion.
This page provides summary hazard information on the 286 chemicals that were added to the Toxics Release Inventory in 1994. EPA has developed information summaries on 40 selected TRI chemicals to describe how you might be exposed to these chemicals, how exposure to them might affect you and the environment, what happens to them in the environment, who regulates them, and whom to contact for additional information.
- TRI
Chemical Fact Sheets
Chemical fact sheets for many of the TRI chemicals are available from the collection of New Jersey’s Right to Know Hazardous Substance Fact Sheets.
- TRI Chemicals Classified as OSHA Carcinogens
This is a list of TRI chemicals that are classified as carcinogens under the requirements of the Occupation Safety and Health Administration (OSHA) and, the basis of the classifications. OSHA carcinogens have a 0.1% de minimis concentration limit instead of 1%. Amounts of TRI chemicals present below the de minimis concentration limit in mixtures do not have to be included in threshold determinations or release and other waste management calculations.
- ATSDR TOXFAQS
These are a series of summaries developed by the Agency for Toxic Substances and Disease Registry (ATSDR) that contain frequently asked questions about the health effect for 60 hazardous substances. About 50 of these chemicals are also TRI chemicals.
