Description of key information

Although the key study provided an unbounded EC50 value, a bounded value is used as key value for the chemical safety assessment

Key value for chemical safety assessment

EC50 for freshwater algae:
100 mg/L

Additional information

Short-term toxicity of NMMO to algae was investigated by exposing Desmodesmus subspicatus during 72 hours in a static test, according to the OECD guideline 201. This resulted in an EC50(72h) value of > 100 mg/L and an NOEC(72h) >= 100 mgL, both based on growth rate.
