Applicant's summary and conclusion
- Validity criteria fulfilled:
- not applicable
- Conclusions:
- the 96 hr IC50 of sodium thiocyanate to L. minor was 3663 mg/L
- Executive summary:
This study was designed to evaluate the acute toxicity of sulphocyanic sodium to Lemna minor using the growth inhibition test. The experimental approach involved exposure of L. minor to sulphocyanic sodium under standard laboratory conditions. The results indicated that the 96 hr IC50 to L. minor using the relative growth rate was 3663 mg/L.
