Description of key information

EC50 for Sodium diacetate is calculated to be  higher than 164 mg/L in Algae.

Key value for chemical safety assessment

EC50 for freshwater algae:
164 mg/L

Additional information

To determine LC50 of Sodium diacetate in algae read across was applied and the value was calculated according to the method of Toxic Unit Summation.

Based on published experimental results obtained with the supporting substance Acetic acid (8d EC50= 90mg/L) and Sodium acetate acetate (72h EC50> 417,92 read-across from Potassium acetate), the read-across approach is applied and the 72 h EC50 for the Sodium diacetate calculated to be 164 mg/L.
