Description of key information

Sodium lactate fully dissociates into Na+ ions and lactate. The ecotoxicology of sodium lactate can be understood in terms of the ecotoxicology of lactic acid. molar ratio to convert from lactic acid by weight to sodium lactate by weight is 1.24.
90-day LOEL for Tilapia is 2.18 mg/L; this corresponds to 2.71 mg/L sodium lactate.

Lactic acid is a ubiquitous and essential molecule of life in all vertebrates. It is highly soluble in water, and will not (significantly) accumulate in water. As such, a long-term effect in water for fish is likely to be due to physical effects (pH, electrostatic) at the gill membrane, rather than to systemic toxicity.
