Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
1272W94 was tested for its acute toxicity over a 48hr exposure period to Daphnia Magna in a static test. The EC50 (48hrs) was determined to be >100mg/Land the 48hr NOEC was >100mg/L
Executive summary:

1272W94 was tested for acute toxicity to Daphnia Magna using an immobilisation test as described on the Official journal of the European Communities Method C2. The mean measured concentration of the test material remained at 100% of the nominal exposre concentration throughout the test. The LC50 at 48hrs exposure was determined to be >100mg/L
