In addition to viewing maps based on release quantities, you can also view maps based on risk-screening scores, which are estimates of potential human health risk following exposure to TRI chemicals. These unitless risk-screening scores (RSEI Score) are generated by EPA's Risk-Screening Environmental Indicators (RSEI) model, and allow you to compare the relative potential for human health impacts across various locations. For more on RSEI, see the Hazard and Potential Risk of TRI Chemicals section.
As with any dataset, there are several factors to consider when using the TRI data. Key factors associated with data used in the National Analysis are summarized in the Introduction. For more information see Factors to Consider When Using Toxics Release Inventory Data.
This page was published in March 2022 and uses the 2020 TRI National Analysis dataset made public in TRI Explorer in October 2021.
