TRI only requires covered facilities to report on chemical releases to the environment and various waste management practices. TRI reports do not include information about the exposures people may
experience as a consequence of chemical use, release or transfer. While exposure data are essential for efforts to assess the safety of chemical releases or to characterize potential health risks, TRI currently does not require facilities to monitor or estimate exposures.
WHO MAY BE EXPOSED AS A RESULT OF CHEMICAL USE AT TRI FACILITIES?
Toxic chemical use, release or transfer may result in hazardous exposures to the following groups:
Community residents - living where releases occur, where off-site transfers are stored or processed, or along transportation corridors used for waste shipments
Workers - in the industries producing, using and disposing of toxic chemicals
Consumers - of products that are manufactured from toxic chemicals.
WHERE CAN I GET MORE INFORMATION ABOUT CHEMICAL EXPOSURES?
Scorecard tracks sources of available exposure data covering different environmental media (air, water, etc.). Scorecard currently provides online access to ambient air exposure data (see Criteria Air Pollutants or Hazardous Air Pollutants). However, Scorecard reports do not provide information about the specific exposures communities experience as a result of reported chemical releases from TRI facilities.
The best available resource for estimating exposures attributable to TRI facilities is EPA's Risk-Screening Environmental Indicators Model, which provide facility-specific ambient air exposure estimates.
