Description of key information

The algal inhibition of the test substance was assessed according to OECD Test Guideline 201. The 72 hour EC50 (growth rate) was 5.4 mg/L with a NOEC of 2.8 mg/L and LOEC of 8.8 mg/L. It was not possible to calculate 95% confidence limits for the ErC50 value as the data generated did not fit the models available for the calculation of confidence limits

Key value for chemical safety assessment

EC50 for freshwater algae:
5.4 mg/L
EC10 or NOEC for freshwater algae:
2.8 mg/L
