Description of key information

- SCP liquor was regarded as readily biodegradable despite of slightly deviant results with the two test samples.
- Biodegradation 81% (28 d) (OECD 301 E and EU Method C.4-B)
- Biodegradation 68.1% (28 d) (OECD 301 E and EU Method C.4-B)

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Two SCP liquor samples were tested for ready biodegradability (key studies). The other sample passed the ready biodegradability criterium (70%) clearly (81%, 28d) and the other sample slightly failed (68.1%, 28d), showing in any case obvious inherent biodegradability.

By overall estimation of the results it is still concluded that SCP liquor can be regarded as readily biodegradable.
