Description of key information

Information available indicates that this category can be considered readily biodegradable.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

Degradation was achieved at varying levels in the available tests. Two tests indicate that the substance is readily biodegradable (ignoring the 10 day window). As the 10 day window is not relevant to UVCB substances, therefore the substance is considered readily biodegradable.

Two studies indicate that this category is not readily biodegradable (Lee, 1993, and Canale, 1999). The study by Lee (1993) has been read across from the other gas oils category.
