Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
No biodegradation was observed after 28days in the manometric respirometry test (OECD 301F.) . The 4-amino-m-cresol is not readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
A ready biodegradation test, following the OECD 301F guideline, was conducted on 4-amino-m-cresol. The substance was tested at 100 mg /L. The inoculum was activated sludge collected from the aeration tank of the facility's sewage treatment plant. The test treatment and inoculum blank were measured in duplicate while reference and toxicity control were measured singly. The deviation between replicate treatments was <20% (met the validity criteria of the guideline).
The % biodegradation at the end of the test was 0% indicating that 4 -amino-m-cresol was not readily biodegradable
The reference material, sodium benzoate, met the validity criteria for the test, greater than 60% biodegradation within 14 d, and within the 10 d window. The test material was not inhibitory to the test system as verified in the toxicity control.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
