ALETHEIA's chemical-safety data is cited, not scraped. Every hazard classification,
regulatory listing, and exposure figure is attributed to the public authority that issued it. This page
lists those authorities. It answers “who our data comes from” — which is distinct from
“who we engage with”; for the latter, see the
engagement registry and
agency directory.
Not listed ≠ safe. If a substance is not listed by an authority below, that means the
authority has not assessed or has not restricted it — not that it is known to be safe. Absence of a
listing is absence of assessment, not a clearance.
How determinations reach us. Some determinations are surfaced through public-domain
aggregators. For example, IARC carcinogen classifications are surfaced via the U.S. EPA CompTox Chemicals
Dashboard's public-domain aggregation and cited to the underlying IARC monograph. Where a source is in the
public domain (U.S. federal and state) we cite it as a provenance and trust feature; where reuse is
conditioned on attribution (EU and other open-data bodies) we attribute the issuing authority.

Established chemical-safety and toxicology data sources we do not yet ingest — each is a candidate we verify for machine access and licence before use.
