List Version Source flow Name there Why this flow
EF 3.1 fe0acd60-3ddc-11dd-a655-0050c2490048 helium The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu 2026-v1 4b26cf7a-1eea-5b5f-870f-d24833fa5929 Helium The CAS numbers are the same (7440-59-7); both name the same compartment.
ecoinvent 3.12 a91c4052-de24-456d-a1d5-4e2d9db201e3 Helium A curator's mapping table (ecoinvent-3.11-biosphere-EF-3.1-biosphere) names this flow.
ecoinvent 3.8 a91c4052-de24-456d-a1d5-4e2d9db201e3 Helium A curator's mapping table (ecoinvent-3.8-biosphere-EF-3.1-biosphere.json) names this flow.
