List Version Source flow Name there Why this flow
EF 3.1 fe0acd60-3ddc-11dd-aadf-0050c2490048 polycyclic aromatic hydrocarbons The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu 2026-v1 8a189989-787e-557d-aa5d-db1961984285 PAH, Polycyclic Aromatic Hydrocarbons The CAS numbers are the same (130498-29-2); both name the same compartment.
ecoinvent 3.12 3e5d7d91-67d7-4afb-91dd-36fab58e4685 PAH, Polycyclic Aromatic Hydrocarbons A curator's mapping table (ecoinvent-3.11-biosphere-EF-3.1-biosphere) names this flow.
ecoinvent 3.8 3e5d7d91-67d7-4afb-91dd-36fab58e4685 PAH, Polycyclic Aromatic Hydrocarbons A curator's mapping table (ecoinvent-3.8-biosphere-EF-3.1-biosphere.json) names this flow.

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.
