Duration:
96 h
Dose descriptor:
LC50
Effect conc.:
> 100 mg/L
Nominal / measured:
nominal
Conc. based on:
test mat.
Basis for effect:
mortality (fish)
Results with reference substance (positive control):
The toxic response obtained on the reference item K2Cr2O7 for the Fish batch number 280818 gives a LC50-24h of 202.4 mg/L [176.7 – 233.0], in accordance with historical data obtained by the laboratory.

Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Conclusions:
The results obtained for the test item « W3803S04SOLSIV» on the toxicological endpoint “mortality” give a LC50-96h higher than 100 mg/L (highest tested concentration), value expressed in nominal test item concentration.
