Toxics Release Inventory
TOXNET's TRI (https://toxnet.nlm.nih.gov/cgi-bin/sis/htmlgen?TRI) now includes all reporting years (1987-2001). Previously, 1995-2001 was available.

TRI is a series of databases that constitute the annually published toxic releases files on the National Library of Medicine's (NLM) Toxicology Data Network (TOXNET®). TRI contains information on the annual estimated releases of toxic chemicals to the environment and is based upon data collected by the Environmental Protection Agency (EPA). Mandated by the Superfund legislation, TRI's data covers air, water, land, and underground injection releases, as well as transfers to waste sites, and waste treatment methods and efficiency, as reported by industrial facilities around the United States. TRI also includes data related to source reduction and recycling.

Users can check one or more TRI boxes to select the year(s) to search. The first choice (also the default) is the most recent file year available. This is followed by preceding years, which now go back to 1987, the starting year for collection of this data. A "Select all" option allows all years to be searched simultaneously.
