Applicant's summary and conclusion
- Interpretation of results:
- readily biodegradable
- Conclusions:
- 2,2,2-trifluoroacetamide was estimated to be 50% biodegradable in water in 38 days (half-life) indicating that 2,2,2-trifluoroacetamide is readily biodegradable in water since the half life is less than the threshold of 60 days (to qualify the chemical as persistent)
- Executive summary:
Based on level III fugacity model 2,2,2-trifluoroacetamide was estimated to be 50% biodegradable in water in 38 days (half-life) indicating that 2,2,2-trifluoroacetamide is readily biodegradable in water since the half life is less than the threshold of 60 days (to qualify the chemical as persistent)
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
