Description of key information

The substance exhibited low acute toxicity to freshwater algae. In a 72-hour study with Desmodesmus subspicatus the ErC50 for inhibition of the growth rate was 111.9 mg/L.

Key value for chemical safety assessment

EC50 for freshwater algae:
111.9 mg/L
EC10 or NOEC for freshwater algae:
62.4 mg/L

Additional information

The algal toxicity of the registration item methyl benzoate to the freshwater green alga Desmodesmus subspicatus was studied in a valid test in accordance with OECD TG 201. The substance inhibited the cell growth and the ErC50 value was 111.9 mg/L. Complete growth inhibition was seen at 300 mg/L or greater.
