Description of key information

With high probability acutely not toxic to aquatic algae.

Key value for chemical safety assessment

EC50 for freshwater algae:
313 mg/L
EC10 or NOEC for freshwater algae:
50 mg/L

Additional information

In a GLP guideline study according to OECD 201 the EC50 value on the growth rate of green algae was determined to be 313 mg/L (Rohm and Haas 06RC-262, 2007). The NOEC was observed to be 50 mg/L. Therefore the tested substance is considered as acutely not harmful to algae.
