List	Version	Source flow	Name there	Why this flow
EF	3.1	fe0acd60-3ddc-11dd-ad94-0050c2490048	xylene (all isomers)	The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu	2026-v1	631f08c1-5aae-55a5-bb34-906471791422	Xylene	The CAS numbers are the same (1330-20-7); both name the same compartment.
ecoinvent	3.12	a1d277aa-7aea-4b5e-8aa9-2789ba8ff333	Xylenes, Unspecified	A curator's mapping table (ecoinvent-3.11-biosphere-EF-3.1-biosphere) names this flow.
ecoinvent	3.8	a1d277aa-7aea-4b5e-8aa9-2789ba8ff333	Xylene	A curator's mapping table (ecoinvent-3.8-biosphere-EF-3.1-biosphere.json) names this flow.
