Description of key information

The 72h-ErC10 for freshwater algae is 81.8 mg/L (nominal, tet material) and the 72h-ErC50 is 254 mg/L (nominal, tet material).

Key value for chemical safety assessment

EC50 for freshwater algae:
254 mg/L
EC10 or NOEC for freshwater algae:
81.8 mg/L

Additional information

One study, valid without restrictions, with freshwater algae P. subcapitata is available. The test was performed under GLP. All measured test concentrations were close to nominal, therefore effects were based on nominal test concentrations.

The 72h-ErC10 is 81.8 mg/L (nominal, test material).

The 72h-ErC50 is 254 mg/L (nominal, test material).
