Applicant's summary and conclusion
- Validity criteria fulfilled:
- not specified
- Conclusions:
- X330 was tested according to EN ISO 6341(1996) (NFT 90301) in order to determine which concentration of the active ingredient stops 50% of Daphnia Magna mobility after 24 hours of exposure. The estimated EC50 (24 hr) was determined at 5654 mg/l with a confidence interval at 95% between 4404 and 7618 mg/l.
- Executive summary:
X330 was tested according to EN ISO 6341(1996) (NFT 90301) in order to determine which concentration of the active ingredient stops 50% of Daphnia Magna mobility after 24 hours of exposure. The estimated EC50 (24 hr) was determined at 5654 mg/l with a confidence interval at 95% between 4404 and 7618 mg/l.
