List Version Source flow Name there Why this flow
EF 3.1 08a91e70-3ddc-11dd-9204-0050c2490048 benzene The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu 2026-v1 c11aacbf-b17e-5f72-838d-2da89fedc298 Benzene The CAS numbers are the same (71-43-2); both name the same compartment.
ecoinvent 3.12 1bb6a502-3ff9-4a79-835c-5588b855f1f5 Benzene A curator's mapping table (ecoinvent-3.11-biosphere-EF-3.1-biosphere) names this flow.
ecoinvent 3.8 1bb6a502-3ff9-4a79-835c-5588b855f1f5 Benzene 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.
