Transparency: Finding Public Information on Chemicals
EPA and other federal and international agencies maintain a variety of sites where you can find information on:
- Whether and how chemicals are regulated
- What chemicals are in your community
- What EPA and other agencies know about the health and environmental effects of specific chemicals
Chemical Information Sources:
Chemical Data Access Tool
to find health and safety data that has been submitted to the Agency, under authorities in sections 4, 5, and 8 of the Toxic Substances Control Act (TSCA), as well as declassified informatoin. The tool is also available on
Data.gov.
TSCA Chemical Substance Inventory to get a list of each chemical substance that is manufactured or processed in the United States.
