- Tartaric acid and its salts (e.g. Calcium tartrate) are not expected
to be toxic to FISH.
- LC50 (fish, 96h, OECD203): >100 mg/L used as key study
- LC50 (Fish, 96 hr, ECOSAR) = 506 g/L used as supporting study
- LC50 (Fish (SW), 96 hr, ECOSAR) = 884 g/L used as supporting
LC50 values higher than 100 mg/L were predicted for tartaric acid by
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 fish.
