List	Version	Source flow	Name there	Why this flow
EF	3.1	fe0acd60-3ddc-11dd-a7ff-0050c2490048	barium	The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu	2026-v1	3b4b14d1-ad6a-5f1a-b16e-d9872e7a4901	Barium	The CAS numbers are the same (7440-39-3); both name the same compartment.
ecoinvent	3.12	99cd88f6-16b7-4b28-895c-2f42101f634b	Barium II	A curator's mapping table (ecoinvent-3.11-biosphere-EF-3.1-biosphere) names this flow.
ecoinvent	3.8	99cd88f6-16b7-4b28-895c-2f42101f634b	Barium	A curator's mapping table (ecoinvent-3.8-biosphere-EF-3.1-biosphere.json) names this flow.
