Applicant's summary and conclusion

Conclusions:
The atmospheric oxidation half life of 2,2,2-trifluoroacetamide was estimated using level III multimedia model it indicates that 2,2,2-trifluoroacetamide is persistent in air medium as the half life period of 2,2,2-trifluoroacetamide in air is only 180 days. From this it is concluded that 2,2,2-trifluoroacetamide is not rapidly phototransformed in air.

Executive summary:
