Description of key information

With high probability acutely not harmful to aquatic algae.

Key value for chemical safety assessment

EC50 for freshwater algae:
180 mg/L
EC10 or NOEC for freshwater algae:
32 mg/L

Additional information

To determine the acute toxicity to aquatic algae a static GLP test was performed using Pseudokirchneriella subcapitata as test organisms in an approach according to OECD guideline 201 (BASF/IPO Institute 2012). After 72 hours of exposure an EC50 > 180 mg/L was estimated while the NOEC was calculated to be 32 mg/L, both related to the endpoint growth rate and the analytically verified nominal concentrations.
