Results and discussion

Effect concentrations
Duration:
48 h
Dose descriptor:
EC50
Effect conc.:
> 100 mg/L
Basis for effect:
mortality
Details on results:
No EC50 value could be determined as no immobilisation of Daphnia Magna could be observed.
Results with reference substance (positive control):
Potassium Dichromate: EC50=1.14mg/L at 48 hours

Applicant's summary and conclusion

Conclusions:
The EC50 value for D-100 is above 100 mg/L as no immobilisation of daphnia magna could be observed.
Executive summary:

The EC50 value for D-100 is above 100 mg/L as no immobilisation of daphnia magna could be observed.
