Results and discussion
Effect concentrations
- Duration:
- 96 h
- Dose descriptor:
- NOEC
- Effect conc.:
- >= 0.05 mg/L
- Results with reference substance (positive control):
- Result for 10 fish with refernce substance potassium chromate (K2Cr2O7) was equal to standard result at the laboratory.
- Reported statistics and error estimates:
- Not possible to perform.
Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Conclusions:
- The test substance did not show any effect on fish up to the solubility limit of 0.05 mg/l. NOEC was not possible to determine, but the registrant conclusion is that Gelpaste Urea not is acute toxic to fish.
