Use Tox-App (see Figure 1), a free mobile app for iOS users from the National Library of Medicine (NLM), to search for industrial facilities that reported releasing certain chemicals into the environment (based on data from the US EPA TRI program). Tox-App includes a subset of about 100 TRI chemicals for the most current TRI year. You can download Tox-App from the Apple App Store: https://itunes.apple.com/us/app/tox-app/id1227471020?mt=8

Tox-App is based on NLM online tool TOXMAP and provides some of the basic TOXMAP functions, including:

  • Search for reporting facilities by name or state
  • Browse for facilities by chemical, state, or county
  • View locations of reporting facilities on an interactive map
