Description of key information

A 72-hour ECr50 of ca. 90 mg/L (TWA) and a NOEC of 6 mg/L (TWA) have been determined for the effects of the test substance on growth rate of the freshwater algae Selenastrum capricornutum (new name: Pseudokirchnerella subcapitata) in a reliable study. A 72-hour ECb50 of 36 mg/L (TWA) has been determined for effects on biomass. 

Key value for chemical safety assessment

EC50 for freshwater algae:
36 mg/L
