Description of key information

With high probability not harmful to aquatic algae.

Key value for chemical safety assessment

EC50 for freshwater algae:
120 mg/L
EC10 or NOEC for freshwater algae:
120 mg/L

Additional information

The toxicity of the test substance to Desmodesmus subspicatus was investigated in a GLP guideline study according to OECD 201. The EC50 (72h, growth rate) was determined to exceed the highest tested concentration of 120 mg/L, based on the analytically verified nominal concentration (BASF SE 60E0535/11X283, 2012). Therefore, the test substance is considered to be "with high probability not harmful to aquatic algae".
