TOXNET's TRI (http://toxnet.nlm.nih.gov/cgi-bin/sis/htmlgen?TRI
<http://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  <http://www.nlm.nih.gov/> National Library of
Medicine's (NLM)  <http://toxnet.nlm.nih.gov/> Toxicology Data Network
(TOXNET(r)). TRI contains information on the annual estimated releases of
toxic chemicals to the environment and is based upon data collected by the
<http://www.epa.gov/> 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 goes back to 1987, the
starting year for collection of this data. A "Select all" option allows all
years
to be searched simultaneously.
