Note: The following equation was used to determine evolved CO2: mg CO2 from test vessel=((TIC mg/L x 3.667) x Vol. KOH Tx[L])+ Sum [(TIC mg/L in previous aliquots removed x 0.007 L x 3.667)]
Where: 3.667 is the converstion factor (44/12) for carbon to carbon dioxide.
Vol. KOH Tx is the volume of KOH trap at the particular sampling interval.
0.007 L is the KOH sampling volume (7.0 mL)

Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Remarks:
- ref substance degradation >60% by 14d (89.52%), <5% inorganic C in medium at test start (4.72%), diff in test substance degradation <20% (0.62% 14d, 7.08% 28d), CO2 evol in controls ≤40 mg/L (17.50 mg/L)
- Interpretation of results:
- not readily biodegradable
- Conclusions:
- DiBrORMA was 3.69% biodegraded in a 28-day OECD 301B test.
- Executive summary:
Ready biodegradability of DiBrORMA was assessed according to OECD 301B guidelines. Duplicate flasks were used for blanks and the test substance, with single flasks for procedural control (sodium benzoate), and toxicity control samples. The reference substance was degraded adequately by day 7. The toxicity control was biodegraded 43.02 % by day 14. The test substance was biodegraded (3.69%) by day 28. Thus, DiBrORMA is not considered readily biodegradable but is not inhibitory to biodegradation.
The test was conducted according to internationally accept guidelines and is GLP compliant. It is reliable without restrictions and is suitable for Risk Assessment, Classification & Labelling, and PBT Analysis.
