Remarks on result:
other: 301C
Validity criteria fulfilled:
not specified
Interpretation of results:
not readily biodegradable
Conclusions:
In a biodegradation test in aerobic aqueus medium, the test substance was demonstrated as not readily biodegradable.
Executive summary:

Test method of activated sludge according to guideline OECD 301 C. A theoretical BOD of 8.4% with activated sludge inoculum and using the Japanese MITI test, suggests that test item is considered to be not readily biodegradable.

Description of key information

Key study. According to test method of activated sludge (aerobic conditions), following guideline OECD 301 C, the test item was determined to be not readily biodegradable.

Key value for chemical safety assessment

Biodegradation in water:
not biodegradable
