Applicant's summary and conclusion

Conclusions:
The effective concentration (EC50) value of 2,2,2-trifluoroacetamide in aquatic invertebrate (Daphnia Magna) in a 48 hr study based on intoxication effect was estimated to be 133.1068 mg/L.
Executive summary:

The effective concentration (EC50) value of 2,2,2-trifluoroacetamide in aquatic invertebrate (Daphnia Magna) in a 48 hr study based on intoxication effect was estimated to be 133.1068 mg/L. Considering only the value from CLP Criteria for aquatic classification of the substance , it is concluded that 2,2,2-trifluoroacetamide does not exhibit short term toxicity to aquatic invertebrate (Daphnia Magna)
