EPA Opens Access to Database on Chemical Hazard, Exposure and Toxicity Data


The U.S. Environmental Protection Agency (EPA) is making it easier to find chemical information online. EPA is releasing a database, called ToxRefDB, which allows scientists and the interested public to search and download thousands of toxicity testing results on hundreds of chemicals. ToxRefDB captures 30 years and $2 billion of testing results.

“Tens of thousands of chemicals are in commerce and current chemical testing is expensive and time consuming. Results from chemical testing are scattered throughout different sources,” said Dr. Robert Kavlock, director of EPA’s National Center for Computational Toxicology. “ToxRefDB allows the public to search, find and compare available studies about chemical toxicity and potential health effects.” 

ToxRefDB (Toxicity Reference Database) captures thousands of in vivo animal toxicity studies on hundreds of chemicals. The database:

  • Stores detailed study design, dosing, and observed treatment-related effects using standardized vocabulary.
  • Provides detailed chemical toxicity data, for the first time, in a publically accessible and searchable format.
  • Enables linkages to other public hazard, exposure and risk resources by integrating with ACToR (Aggregated Computational Toxicology Resource).
  • Captures over 30 years and $2 billion of animal testing results.
  • Connects to another EPA chemical screening tool called ToxCast, a multi-year, multi-million dollar effort that uses advanced science tools to help efficiently (~$20K per chemical) understand biological processes impacted by chemicals that may lead to adverse health effects.
