List Version Source flow Name there Why this flow
EF 3.1 08a91e70-3ddc-11dd-9293-0050c2490048 particles (PM2.5) The consensus list is built from this one, so this row is the flow itself rather than something matched to it.
bafu 2026-v1 8b8a7efa-0c09-5ed0-a971-a31771079084 Particulates, < 2.5 Um This substance answers to the name the row carries; both name the same compartment.
