Additional information

Short-term toxicity to fish:

Weight of evidence: Read-across from experimental results on the analogues substances Sodium Acetate and Potassium Acetate. The 96h-LC50 for Calcium acetate is calculated to be between: > 96.45 - > 402.92 mg/L.

Long-term toxicity to fish:

Data waiving: In accordance with column 2 of REACH Annex IX, the study does not need to be conducted since the chemical safety assessment indicates the no need to investigate further the effects on aquatic organisms.

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).

Long-term toxicity to aquatic invertebrates:

Data waiving: In accordance with column 2 of REACH Annex IX, the study does not need to be conducted since the chemical safety assessment indicates the no need to investigate further the effects on aquatic organisms.

Toxicity to aquatic algae and cyanobacteria:

Key study: Read-across from experimental results obtained with the category analogue Potassium acetate. Study according to ISO guideline and GLP compliance. The 72h- EC50 value for Calcium Acetate is calculated to be > 402.92 mg/L with Skeletonema costatum. The NOEC value was estimated to be 402.92 mg/L.

Toxicity to microorganisms:

Key study: Read-across from experimental data on the category analogue Sodium Acetate. The estimated 16h-EC50 for Pseudomonas putida with the substance Calcium acetate is calculated to be 6.94 g/L, and EC10 is estimated to 3.37 g/L.
