TRI National Analysis

Risk Trend

EPA's RSEI model also estimates risk “scores” that represent relative human health risk from chronic exposure to TRI chemicals. These risk scores can be compared to RSEI-generated risk scores from other years. RSEI scores are different from RSEI hazard estimates in that RSEI scores consider the location of the release, its fate and transport through the environment, and the route and extent of potential human exposure. The following graph shows the trend in the RSEI score compared to the trend in the corresponding pounds of TRI chemical releases.

 

From 2007 to 2017:

  • The overall RSEI score estimate decreased by 62%, while corresponding pounds released decreased by 44%.
  • Of the types of releases modeled by RSEI, air releases, by far, contribute the most to the RSEI scores.
