EF 3.1 1a9cf04e-2a7b-4e36-bf05-c4c6b630e4eb Xenon-135m The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
agribalyse 3.2 0368655b-435d-58b6-af68-253ef42182c9 Xenon-135m The CAS numbers are the same (378784-92-0); both name the same compartment.
bafu 2026-v1 2d271dd7-0bcc-5060-9400-6dae54321eb3 Xenon-135m This substance answers to the name the row carries; both name the same compartment.
bafu 2026-v1 8983b9a4-7739-59bd-9f3d-e78f01e8b908 Xenon-135m This substance answers to the name the row carries; both name the same compartment.
ecoinvent 3.12 b3fd01ce-4eb3-461f-8639-4c7aa166f40e Xenon-135m The CAS numbers are the same (378784-92-0); both name the same compartment.
ecoinvent 3.8 b3fd01ce-4eb3-461f-8639-4c7aa166f40e Xenon-135m The CAS numbers are the same (378784-92-0); both name the same compartment.
