Description of key information

Acutely harmful to aquatic plants

Key value for chemical safety assessment

EC50 for freshwater algae:
50.8 mg/L
EC10 or NOEC for freshwater algae:
6.27 mg/L

Additional information

Acute toxicity to algae was assessed in a static GLP approach according to guideline OECD 201 using Pseudokirchneriella subcapitata as test organism (BASF 2012). After 72 hours of exposure an EC10 of 6.27 mg/L was estimated while the EC50 is about 50.8 mg/L, both related to the endpoint growth rate and the mean measured concentration.
