Description of key information

The toxicity of the test substance to the aquatic algae Pseudokirchneriella subcapitata was investigated in a GLP guideline study according to OECD 201 (BASF SE 60E0446/01X049, 2013).

The ErC50 (72h) determined to be 61.6 mg/L, based on analytically verified nominal concentrations. The ErC10 (72h) was determined to be 22.5 mg/L, based on analytically verified nominal concentrations.

Key value for chemical safety assessment

EC50 for freshwater algae:
61.6 mg/L
EC10 or NOEC for freshwater algae:
22.5 mg/L
