Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
The test substance can be considered to be "readily biodegradable".
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Regarding biodegradation in water (screening tests) one experimental result is available for the test substance. The study was conducted in compliance with the Principles of Good Laboratory Practice (GLP) and all validity criteria of the corresponding guideline were met.
The biodegradability of the test substance was investigated according to OECD guideline 301B and EU-method C.4 -C. The test item was tested using a concentration of 20 mg carbon/L in test medium. Aniline was chosen as reference item. Activated sludge was used as inoculum (conc. in the test 25 mg/L). The test was left running for 28 days. Degradation of the reference item was 67% after eight days.
The following data could be determined for the test item :
10-day-window : day 2 - 12
degradation at the end of 10-day-window :78%
degradation at the end of the test : 86%
pass level : 60% at the end of 10-d-window
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).
