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.
Lactic acid is a ubiquitous and essential molecule of life; acute
effects, as well as (external) long-term effects are most likely the
results of physical processes (pH-effect; electrostatic effects).
Chronic effects are not relevant in the context of risk assessment.
PNECs are derived based on the acute effects. PNECs are below the
chronic no-effect levels, insofar available.
Lactic acid is practically nontoxic to algae. This is an additional
indication that the short-term effects observed for fish and daphnids
are of a physical nature, since algae are less sensitive to pH effects
than (especially) fish.
Lactic acid does not have to be labeled for environmental effects, and
no short or long-term effects are expected for any exposure levels that
do not lower the pH to unacceptable levels. As such no relevant hazards
