Additional information

The toxicity of the test substance on aquatic algae was investigated in a GLP guideline study according to OECD 201 with Pseudokirchneriella subcapitata [BASF SE, 2012]. The substance had no observable inhibitory effect on algae growth up to its saturation limit in the test media and under test conditions. The EC50 value (based on growth rate after 72 h of exposure) was determined to be > 100 mg/L (nominal).
