Results and discussion
Effect concentrationsopen allclose all
- Duration:
- 72 h
- Dose descriptor:
- EC50
- Effect conc.:
- > 2.108 mg/L
- Nominal / measured:
- meas. (initial)
- Conc. based on:
- test mat.
- Basis for effect:
- growth rate
- Duration:
- 72 h
- Dose descriptor:
- NOEC
- Effect conc.:
- > 2.108 mg/L
- Nominal / measured:
- meas. (initial)
- Conc. based on:
- test mat.
- Basis for effect:
- growth rate
- Details on results:
- As the percent change in analysed concentration over nominal concentration at the end of test was > 20 %, the results were expressed as initial measured concentration (i.e. 2.1 085 mg/L).
- Reported statistics and error estimates:
- Statistical analysis was not carried out as there was no inhibition of growth at the limit concentration tested.
Applicant's summary and conclusion
