Description of key information

100 mg/L lactic acid (nomical formulation, nominal active is 88 mg/L) is not inhibiting to activated sludge. This corresponds to 121 mg/L calcium lactate

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
121 mg/L

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.
