Additional information

Calcium lactate fully dissociates into Ca2+ ions and lactate. The ecotoxicological effects of lactate in the environment can be understood in terms of the ecotoxicological effect of lactic acid. Calcium ions - i.e. simple calcium salts, are non-toxic.

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.
