Applicant's summary and conclusion
Validity criteria
- Validity criteria fulfilled:
- yes
- Conclusions:
- The registration substance was tested in an OECD 303A Sewage Treatment Plant Simulation Test over 37d using a test item concentration of 24.8 mg/L. After the run-in phase the test item was monitored over 17d using 24h composite samples and DOC Analysis. Based on these measurements a Biodegradation rate of 62% +/- 3% was determined. This biodegradation rate is in line with the degradation found in a ready and in an inherent test (see IUCLID Chapter 5.2.1).
