Description of key information

Acutely harmful to aquatic plants

Key value for chemical safety assessment

EC50 for freshwater algae:
19.2 mg/L
EC10 or NOEC for freshwater algae:
3.46 mg/L

Additional information

Acute toxicity to algae was investigated in a static GLP test according to OECD guideline 201 using Pseudokirchneriella subcapitata as test organism (BASF 2012). After 72 hours an EC50 of 19.2 mg/L and a NOEC of 3.46 mg/L were estimated based on the endpoint growth rate and the mean analytically determined concentrations.
