Description of key information

The 72-hour ErC50 and the 72-hour EbC50 of SR28043 in a static test system were > 0.305 mg/L (geometric mean of measured concentrations 
during the test in a saturated solution obtained from a loading rate of 100 mg/L), for Scenedesmus subspicatus.
The NOEC at 72 hours was ≥ 0.305 mg/L based on both the specific growth data and biomass data.

Key value for chemical safety assessment

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

Additional information

The 72-hour ErC50 and the 72-hour EbC50 were > 0.305 mg/L and the No Observed Effect Concentration (NOEC) after 72 hours was ≥ 0.305 mg/L (p = 0.05) based on both the specific growth rate data and biomass data.
