EPA Linked Open Data: Substance Registry Service

Metadata Updated: February 24, 2018

Substance Registry Services (SRS) is the Environmental Protection Agency's (EPA) central system for information about substances that are tracked or regulated by EPA or other sources. It is the authoritative resource for basic information about chemicals, biological organisms, and other substances of interest to EPA and its state and tribal partners.

The SRS makes it possible to identify which EPA data systems, environmental statutes, or other sources have information about a substance and which synonym is used by that system or statute. It becomes possible therefore to map substance data across EPA programs regardless of synonym.

The system provides a common basis for identification of, and information about:

Chemicals Biological organisms Physical properties Miscellaneous objects
