2010 Toxics Release Inventory
Idaho State Report
December 2011
Releases in the State of Idaho
In 2010, 95 facilities reported a total of 67.5 million pounds
of toxic chemical releases, an increase of 17%, or 9.7
million pounds, from 2009. Idaho ranks 18th in the nation
for total releases of TRI chemicals.
What is a Release?
A TRI "release" is defined as the amount of a toxic
chemical released on-site (to air, water, underground
injection, landfills, and other land disposal), and the
amount transferred off-site for disposal. All releases values
in this report are listed in pounds released per year.

Persistent, Bioaccumulative, and Toxic (PBT) Chemicals
PBT chemicals are toxic chemicals that persist in the environment and bioaccumulate in food chains, posing risks to
human health and ecosystems. PBT chemicals are a subset of the TRI-listed chemicals that have stricter reporting
requirements. In Idaho, 8 million pounds of total releases of PBT chemicals were reported. This is a decrease of 2 million
pounds, or 21%, from 2009. Lead and lead compounds topped the list in 2010. The PBT chemicals in the table are listed
in descending order of pounds released in 2010.
