Description of key information

Aquatic toxicity data of barium dibenzoate are not available. Read-across to the assessment entities soluble barium substances and benzoic acid is applied for the assessment of barium benzoate since the ions of barium dibenzoate determine its fate and toxicity in the environment. Reliable data available for soluble barium substances and benzoate indicate that the moiety of ecotoloxicological concern are benzoic anions. Based on measured total Ba-levels in the water column, a 96-h LC50 of > 97.5 mg Ba/L (corresponding to > 3.5 mg dissolved Ba/L) is reported for fish whereas the lowest LC50 is set at 44.6 mg/L for benzoic acid. In sum, barium dibenzoate is expected to have a low potential for acute toxicity to fish.
