Description of key information

With high probability the substance is not acutely harmful to aquatic algae.

Key value for chemical safety assessment

EC50 for freshwater algae:
160 mg/L
EC10 or NOEC for freshwater algae:
65 mg/L

Additional information

The effect of the test substance on the growth of Pseudokirchneriella subcapitata was investigated over a 72 -hour period in a Klimisch 1 study conducted according to OECD Guidelines for Testing of Chemicals (2006) No 201, "Freshwater Alga and Cyanobacteria, Growth Inhibition Test". The following results were reported: EC50 (growth rate) of 160 mg/L; EC50 (yield) of 73 mg/L; EC10 (growth rate) of 65 mg/L. The test concentrations were analytically verified. Therefore, it was concluded that the substance is not acutely harmful to aquatic algae.
