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 generated by EPA's Risk-Screening Environmental Indicators (RSEI) model. These unitless scores represent relative human health risk from chronic exposures to TRI chemical releases and allow one to compare potential for risk across locations. For more on RSEI, see the Hazard and Potential Risk of TRI Chemicals section.

TRI Data Considerations

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 January 2021 and uses the 2019 TRI National Analysis dataset made public in TRI Explorer in October 2020.
