Applicant's summary and conclusion

Conclusions:
Under the conditions of the present test, NA-872 AMINOACETAT induced no effects in Daphnia magna exposed to a NA-872 AMINOACETAT
concentration of 100 mg/I. Hence, the 48h-EC50 for Daphnia magna exposed to NA-872 AMINOACETAT was above 100 mg/I, the maximum
concentration to be tested.
