Description of key information

The value for the acute toxicity to aquatic algae and cyanobacteria was derived from a study performed according to the OECD guideline 201 (1984), referenced as Method C.3 of Council Regulation (EC) No. 440/2008. An ErC50 value of 28 mg/L was found after an exposure period of 72 hours. The 72-hr ErC10 value was 5.1 mg/L. The 72-hr NOEC was determined as 2.5 mg/L.

Key value for chemical safety assessment

EC50 for freshwater algae:
28 mg/L
EC10 or NOEC for freshwater algae:
5.1 mg/L
