Chemical Hazard Information Profile

TRI-CHIP Basic Information

TRI's searchable database system that contains hazard information for chemicals included on the Toxics Release Inventory. Searches can be customized across a single chemical, a set of specific chemicals or a TRI chemical category of interest. Click here for instructions on downloading and installing TRI-CHIP version 2.05. Your comments concerning the applicability, user friendliness or potential improvements of TRI-CHIP are greatly appreciated. Please send comments to: John Scalera and Daniel R. Bushman, Ph.D of the Office of Environmental Information /Office of Information Analysis and Access.

TRI-CHIP allows the user to:

  • Easily search for toxicity information on TRI chemicals from multiple information sources
  • Use built in queries to identify chemicals that meet quantitative toxicity criteria such as a lowest observed adverse effect levels (LOAEL) above a specified value
  • Identify all TRI chemicals associated with a critical adverse human health effect of interest
  • Print customized chemical toxicity profile reports
  • Readily move in and out of Web sites where additional chemical toxicity information can be found
  • The screen shot below depicts a typical TRI-CHIP search page

TRI-CHIP contains hazard information for TRI chemicals from the following sources:

  • Toxics Release Inventory (TRI) Federal Register Notices
  • Integrated Risk Information System (IRIS)
  • EPA Office of Pesticide Programs (OPP) Registration Documents
  • Agency for Toxic Substances and Disease Registry (ATSDR)
  • California Environmental Protection Agency (Cal/EPA) - Office of Environmental Health Hazard Assessment (OEHHA)
  • National Toxicology Program (NTP) – 11th Report on Carcinogens
  • International Agency for Research on Cancer (IARC)
