- yes
- Inoculum or test system:
- not specified
- Reference substance:
- acetic acid, sodium salt
- Key result
- Parameter:
- not specified
- Value:
- 2.1
- Sampling time:
- 28 d
- Details on results:
- Points of degradation plot (test substance):
14.7 % degradation after 7 d
19.5 % degradation after 14 d
10.8 % degradation after 21 d
2.1 % degradation after 28 d - Results with reference substance:
- Points of degradation plot (reference substance):
74.6 % degradation after 7 d
78.8 % degradation after 14 d
85.3 % degradation after 21 d
82.7 % degradation after 28 d - Validity criteria fulfilled:
- not specified
- Interpretation of results:
- not readily biodegradable
- Conclusions:
- The test item was determined to be 2.1 % biodegradable after 28 days and cannot be considered readily biodegrable, but not displaying inhibitory effects on the bacteria inoculum at the concentration (2mg/L) used.
