EC number: 281-897-8
CAS number: 84057-80-7
With high probability acutely not harmful to aquatic invertebrates.
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.
