Description of key information

With high probability acutely not harmful to aquatic invertebrates.

Key value for chemical safety assessment

Additional information

For calcium propionate the 48-hr EC50 value on D. magna is >500 mg/L [BASF AG, 1989]. The analogous substance was chosen in order to avoid the pH dependent effect of pure propionic acid solution. Therefore, an acute test with lower effect values performed by Union Carbide Corporation (1976) with the pure acid was not taken into account as it is assumed that effects due to the low pH of the test solution might have occured.
