Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
Readily biodegradable. The test substance exceeded the pass level of 60% within 28 days in two ready biodegradability tests. The 10-day window criterion was met in both studies.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
The ready biodegradation potential of the test substance, Amyl salicylate, was determined using the OECD guideline 301F over a test period of 28-days (key study). Amyl salicylate attained 86% biodegradation after 28-days under the conditions of the test. Biodegradation started on day 2 and reached 80% at the end of the 10-day window. Thus, Amyl salicylate is considered to be readily biodegradable.
The substance was exposed to innoculum, prepared from predominantly domestic sewage, at nominal concentration of 100mg/L at approximately 22 degC. A further similar test sample was used as a toxicity control, which attained greater than 80% degradation after 28-days, thus confirming the non-inhibitory effect of the test substance on the innoculum.
In a supporting CO2 evolution ready biodegradation study, the substance attained 81.3% degradation within 28-days in a CO2 evolution ready biodegradation study. The 10 day window criterion was also met.
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.
