Description of key information
- study conducted according to OECD guideline 302 C (12 May 1981), 28 days exposure of activated sludge with 30 mg of the test item, biodegradation of 37.8% within 28 days, calculated DOC-values between 0 and 53% degradation, read-across MDAB
Additional information
No data about biodegradation are available for the target substance Compimide 183. However, data are available from the source substance MDAB. A justification for read-across is attached to the robust study summary.
Biodegradation in water:screening test:
In a study conducted according to OECD guideline 302C (Modified MITI Test; adopted 12 May 1981) activated sewage sludge was incubated with 30 mg of the test item for 28 days. Inoculated flasks were incubated on a BSB 1000 and BSB601 apparatus. The CO2 was adsorbed by NaOH and the resulting drop was measured on a manometer. Manometer readings for each bottle were recorded once a day for 28 days. COD was measured and BOD/ThOD values were calculated. Measured BOD/ThOD values relvealed a biodegradation of 37.8% within 28 days, whereas the calculated DOC-values were between 0 and 53% degradation. MDAB is regarded to be not readily or inherently biodegradable.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
