Administrative data
Link to relevant study record(s)
- Endpoint:
- activated sludge respiration inhibition testing
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is found to be readily biodegradable and the applied test concentrations are in the range of concentrations that can be expected in the influent of a sewage treatment plant
- Justification for type of information:
- JUSTIFICATION FOR DATA WAIVING
The test substance is established as readily biodegradable. An OECD 301B test was performed, which resulted in 90.7% degradation in 28 days, and the 10-day biodegradation window was met (>60% biodegradation within 10 days). In accordance with Annex VIII Section 9.1.4., Column 2, of Regulation (EC) 1907/2006, the study does not need to be conducted if:
— the substance is found to be readily biodegradable and the applied test concentrations are in the range of concentrations that can be expected in the influent of a sewage treatment plant.
