Applicant's summary and conclusion
- Conclusions:
- Based on the QSAR prediction done using the Danish (Q)SAR Database, the 72 hours EC50 was estimated to be 153.0756 mg/l on Microalgae for substance Ethyl 3,3,3-trifluoropyruvate with growth inhibition effects. Thus based on this value it can be concluded that the substance can be classified as not classified for aquatic environment as per the criteria of CLP regulation.
