Applicant's summary and conclusion

Conclusions:
The 48-hour EC50 of M3MC-Carboxylate for the immobilisation of Daphnia magna was 21.3 mg/L (95% confidence limits of 14.3, 31.6 mg/L).

The ‘no-observed effect concentration’ of M3MC-Carboxylate with Daphnia magna was 14.3 mg/L.
Executive summary:

The 48-hour EC50 of M3MC-Carboxylate for the immobilisation of Daphnia magna was 21.3 mg/L (95% confidence limits of 14.3, 31.6 mg/L). The ‘no-observed effect concentration’ of M3MC-Carboxylate with Daphnia magna was 14.3 mg/L.
