Description of key information

72 h, EC50>104 mg/L, Desmodesmus subspicatus, measured 
72 h, NOEC ≥104 mg/L, Desmodesmus subspicatus, measured

Key value for chemical safety assessment

Additional information

A 72 h EC50 value of >104 mg/L has been determined for the effects of the test substance on growth rate and biomass of the freshwater algae Desmodesmus subspicatus. In the same study a 72 h NOEC value of ≥104 mg/L has been determined. The results are based on geometric mean measured concentration due to rapid loss of test substance from test medium.
