Additional information

A study was conducted to assess the ready biodegradability of the test substance according to OECD Guideline 301B and EU Method C.4 -C, in compliance with GLP. Microbial inoculum (25 mg/L) was added to each preparation bottle of test substance, reference control (aniline), blank control and toxicity control and kept at a constant temperature (20 - 23.1°C) for up to 29 d. Degradation was assessed by the determination of carbon dioxide evolution on Days 0, 2, 4, 7, 9, 11, 14, 18, 23 and 29. The test substance was degraded 53% by 28 d. No toxicity of the test substance was observed as degradation was >25% within 14 d. The reference compound showed 86.8% degradation after 28 d incubation. Under the study conditions, the test substance was considered to be ‘not readily biodegradable’ (Muckle M, 2015).
