Results and discussion

Effect concentrations
Key result
Duration:
72 h
Dose descriptor:
EC50
Effect conc.:
>= 100 mg/L
Nominal / measured:
nominal
Conc. based on:
test mat. (dissolved fraction)
Basis for effect:
growth rate
Remarks on result:
other: * It was not possible to calculate an ErC50 value as no concentration tested resulted in 50% inhibition of growth rate.

Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
The effect of the test item on the growth of Pseudokirchneriella subcapitata has been investigated and gave EC50 values of greater than 100 mg/L. The No Observed Effect Concentration was 10 mg/L.
