EC50 to Daphnia magna
95% confidence limits (mg/L) (Slope of the concentration-response curve)
Statistical procedure used for determination of EC50.
The acute toxicity of HCFO-1224yd(Z) to daphnia was determined in a
48-hour test according to OECD guideline 202. The EC50 (immobilisation)
was determined to be 18.9 mg/l (Geometric mean measured concentration).
There were no deviations from the guideline and the validation criteria
were all met.
