Description of key information

Acutely toxic to aquatic algae.

Key value for chemical safety assessment

EC50 for freshwater algae:
5 mg/L
EC10 or NOEC for freshwater algae:
1.55 mg/L

Additional information

The key study (GLP-guideline study according to OECD 201; BASF SE, 2013) determined a 72 -h ErC50 of 5.00 mg/L and a 72 -h ErC10 of 1.55 mg/L. The nominal concentrations were analytically verified and all validity criteria were met in the test. Based on this data, the substance is acutely toxic to freshwater algae.
