Total releases of toxic chemicals decreased 12 percent from 2011-2012, according to the EPA’s annual Toxics Release Inventory (TRI) report released this week. The decrease includes an eight percent decline in total toxic air releases, primarily due to reductions in hazardous air pollutant (HAP) emissions.
The 2012 data show that 3.63 billion pounds of toxic chemicals were either disposed or otherwise released into the environment through air, water, and land. There was also a decline in releases of HAPs such as hydrochloric acid and mercury, which continues a long-term trend. Between 2011 and 2012, toxic releases into surface water decreased three percent and toxic releases to land decreased 16 percent.
