List Version Source flow Name there Why this flow
EF 3.1 1f314b75-6556-11dd-ad8b-0800200c9a66 tantalum The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu 2026-v1 984171d0-c41f-561b-a1ed-de2706870b34 Tantalum The CAS numbers are the same (7440-25-7); both name the same compartment.
ecoinvent 3.12 775fdf03-b0bb-5c25-b14d-107231d5b2f0 Tantalum A curator's mapping table (ecoinvent-3.11-biosphere-EF-3.1-biosphere) names this flow.

Characterisation factors

3

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.
