Description of key information

Ecotoxicity data are available for HCFO-1224yd(Z) that includes three trophic levels (fish, invertebrates and algae).

The acute toxicity of HCFO-1224yd(Z) to Medaka was determined in a 96-hour test according to OECD guideline 203. The LC50 (mortality) was determined to be 101 mg/l.

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).

The toxicity of HCFO 1224yd(Z) to algae was measured in a 72 -hour study conducted in accordance with OECD TG 201. The EC50 (growth rate) was reported to be >=4.87 mg/l and the NOEC (growth rate was reported to be >= 4.87 mg/l.

The inhibition of activated sludge respiration could not be determined for this substance due to its extremely volatile nature.
