TOXNET's TRI has added TRI 2002; it now includes reporting years 1987-2002. TRI2002 has 93,380 records.

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 goes back to 1987, the starting year for collection of this data
• A "Select all" option allows all years to be searched simultaneously
