List Version Source flow Name there Why this flow
EF 3.1 08a91e70-3ddc-11dd-97e6-0050c2490048 polychlorinated biphenyls The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu 2026-v1 5bf23c1a-9ec9-556e-bcf1-a9a7596db327 Polychlorinated Biphenyls The CAS numbers are the same (1336-36-3); both name the same compartment.

Every implementation that says anything about this flow. Published as is what this list did with the row: where more than one implementation states a number and they agree it publishes it as agreed; where only one speaks, as sole; where they disagree it publishes nothing and asks.
