Description of key information

In an OECD 201 72 hour acute toxicity study with algae (Raphidocelis subcapitata), conducted according to GLP, the EC50 (growth rate) of the test material is 100 mg/L. Additional testing to further define the EC values was not performed since the highest nominal concentration tested, 100% of a 100 mg/L WAF represents the maximum achievable dissolved concentration under the testing conditions.

Key value for chemical safety assessment

EC50 for freshwater algae:
100 mg/L
