Additional information

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

Based on the experimental results obtained with the supporting substance Acetic acid and Sodium acetate (respectively: 96 h LC 50 was 79 mg/L for Fathead minnow, and 96h LC50 was 10g/L for Fathead minnow), the LC 50 for Sodium diacetate for Fathead minnow is calculated to be 184.7 mg/L.
