Current TRI Chemical Information

The Toxics Release Inventory (TRI) makes available information for more than 800 toxic chemicals that are being used, manufactured, treated, transported, or released into the environment since 1987. EPA makes changes (additions, deletions, or changes in definition) to the TRI chemical list. Active and inactive data fields help to track status of chemical coverage. Since the TRI list of reportable toxic chemicals can vary from year to year, EPA created core chemical lists (of 1988, 1991, 1995, 1998, 2000, and 2001) to facilitate year-to-year comparison based on a consistent set of reporting requirements and ensure that changes in TRI release or other waste management amounts do not reflect the addition, deletion, or change in definition of reportable chemicals. EPA also created groupings of specific chemicals of interest by categories to facilitate searches such as Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), Toxics Substance Control Act (TSCA), Hazardous Air Pollutants (HAPs), Metals, Newly Added TRI Chemicals in 1995, Occupational Safety and Health Administration (OSHA, Carcinogens), Persistent Bioaccumulative and Toxic (PBT) Chemicals and Per- and Polyfluoroalkyl Substances (PFAS). EPA also facilitates the searching by possible health end points as defined through 17 effects including developmental, respiratory, and neurological.
