Description of key information
Short-term toxicity to aquatic invertebrates: Weight of evidence: Read-across from experimental results obtained with the analogue substances Potassium acetate and Sodium acetate. The 48h-EC50 for Calcium acetate is calculated to be between: > 370.28 mg/L - > 964.09 mg/L (basis for effect: mobility).

Additional information
Weight of evidence:
Read-across from experimental results obtained with the category analogue Potassium Acetate: Test method was according to OECD 202 and GLP. The 48h-EC50 for Potassium acetate was greater than 459.5 mg/L with Daphnia magna (basis for effect: mobility). The EC0 (48h) was 282 mg/L for Potassium acetate.
Based on molecular weights, read-across approach was applied and the (48 h) EC50 for Calcium acetate is calculated to be > 370.28 mg/L, and the (48 h) EC 0 is 227.5 mg/L.
Read-across from experimental results obtained with the category analogue Sodium Acetate: Test method was according to EU Method C.2 and GLP. Twenty animals (Daphnia magna) were exposed per concentration. The nominal concentrations used in the test were: 0, 20, 40, 60, 100, 200, 300, 600 and 1000 mg/L. The 24h-EC50 was greater than 1000 mg/L (basis for effect: mobility). The 48-h EC50 was greater than 1000 mg/L.
The read-across approach is applied and the (48 h) EC50 for Calcium acetate is calculated to be > 964.09 mg/L.
