- Effect conc.:
- > 1 000 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- inhibition of total respiration
- Remarks:
- respiration rate
- Details on results:
- From the measured inhibition values the EC values could be determined. Up to the highest test concentration no significent inhibition occurred.
- Results with reference substance (positive control):
- EC50 of 3,5-Dichlorphenol: 11.8 mg/L
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- Up to the highest test concentration of 1000 mg/L no significent inhibition occurred. Therefore all EC values, EC20, EC50 and EC80 are above 1000 mg/L.
