Description of key information

Harmful to aquatic algae.

Key value for chemical safety assessment

EC50 for freshwater algae:
58.1 mg/L
EC10 or NOEC for freshwater algae:
19.73 mg/L

Additional information

The toxicity of the test substance to green algae was investigated in a GLP guideline study according to OECD 201 (BASF SE 60E0074/12X207, 2013). In this study, the EC10 was determined to be 19.73 mg/L and the EC50 value was determined to be 58.1 mg/L on the growth rate of Pseudokirchnerella subcapitata (analytically verified values). Hence, the test substance considered to be harmful to aquatic algae.
