PFOS, Perfluorooctanesulfonic acid

Long-chain perfluoroalkyl substance. Immune, developmental, and metabolic signals are seed hypotheses. They are not summed into one hazard number.

Flags: environmental chemical · legacy

Phase-1 numbers are seed hypotheses. They are not curated consensus, not a toxicity total, and not a statement of human risk. Association is not written as causation.

No regulatory assessment is stored. A classification from EFSA, EPA, or another agency would appear here as its own layer. It would not replace the mechanistic scores.
