Source lists
5| List | Version | Source flow | Name there | Why this flow |
|---|---|---|---|---|
| agribalyse | 3.2 | 560c1886-d31a-5960-b0a7-3affbef41666 | Chromium (VI) | The CAS numbers are the same (18540-29-9); both name the same compartment. |
| bafu | 2026-v1 | f22c32fd-3e1c-5724-a5f6-a189abea12fb | Chromium VI | The CAS numbers are the same (18540-29-9); both name the same compartment. |
| ecoinvent | 3.12 | 9bbae55a-35de-4eff-a219-814a9fec5ac2 | Chromium VI | The CAS numbers are the same (18540-29-9); no flow of this substance sat in that compartment, so this one was created for the row. |
| ecoinvent | 3.8 | 9bbae55a-35de-4eff-a219-814a9fec5ac2 | Chromium VI | The CAS numbers are the same (18540-29-9); both name the same compartment. |

}Something wrong here?
A flow can be wrong in three ways, and they are decided differently. Pick the one that matches what you are looking at.
- A row from my list should not reach this flow
- This flow is not that chemical
- The compartment or the unit is wrong
- One of these characterisation factors cannot be this substance's
You do not need to run a build or clone anything. Name the row and say what your evidence is; the measurement is done for you. How contributing works
