Applicant's summary and conclusion
- Conclusions:
- Half life period of 2,2,2-trifluoroacetamide in Soil was observed to be 75 days which exceeds the EPA criteria of 60 days. Based on these half life values it is concluded that 2,2,2-trifluoroacetamide is not readily biodegradable in Soil.
- Executive summary:
Based on level III fugacity model the half life period of 2,2,2-trifluoroacetamide was estimated. Half life period of 2,2,2-trifluoroacetamide in Soil was observed to be 75 days which exceeds the EPA criteria of 60 days. Based on these half life values it is concluded that 2,2,2-trifluoroacetamide is not readily biodegradable in Soil.
