Description of key information
Tartaric acid and its salts are not toxic to aquatic invertebrates.
Key value for chemical safety assessment
Additional information
Tartaric acid was not significant toxic to D. magna in two short-term tests. Furthermore, this substance was predicted to be non-toxic to Daphnia by two valid QSAR models.
Based on the assumption that in dilute aqueous conditions of defined pH, a salt will be fully dissociated and will behave no differently to the parent acid at identical concentration of the particular speciated form present, the aquatic toxicity of tartaric acid salts (i.e. monosodium, monopotassium, sodium potassium, sodium, potassium and calcium tartrate) may be assessed using data specific for tartaric acid. Therefore, also the tartaric acid salts are deemed to be non-toxic to aquatic invertebrates.
