Description of key information

72-hr growth rate EC50: > 100 mg/L test substance.

Key value for chemical safety assessment

EC50 for freshwater algae:
0.008 mg/L
EC10 or NOEC for freshwater algae:
0.008 mg/L

Additional information

72-hr ErC50 = > 0.0078 mg/L based mean measured concentrations of the test substance with additional supporting studies indicating no acute toxicity at or above the test substance water solubility. Based on these observations, and the relevant GHS guidance for classification and labelling, the minimum value resulting in no acute classification (i.e., 100 mg/L) was considered for PNEC derivation.
